    acceleration in motion straight

    C. INDICATOR :

    Explain law newton as basic concepts dynamics and mengaplikasikannya

    problems in dynamics simple

    D. LEARNING OBJECTIVES :

    Through the process of observing, asking questions, discussing, analyzing data,

    mengasosiasi and mengkomunikasi students are able to have knowledge of the concept

    of Dynamic Particle, as well as conservation of Force in our daily lives. and thus the

    character of mutual cooperation, mutual aid, and is active in conducting discussions.

    E. MATERIAL :

    An object can be moved only if given an interesting force or push continuously.

    An object (the train) was driven quickly then released, eventually will stop due to

    friction with the floor. If the force of friction is omitted, then the train will keep moving

    relentlessly. By Galilei said that irregular straight motion (motion in a straight path with

    fixed rate) does not need force.

    Isaac Newton's first law States in which reads:

    When the total force acting on a body is equal to zero or none of the forces

    acting on the object, then each object will move continuously with a speed keep on a

    straight trajectory (motion of the irregular straight) or remain silent

    F = 0

    Newton's law revealing about the nature of things that tend to defend the case.

    This trait is called inertia. An object in a State of silence got the influence of a force,

    then the object will experience a change of pace every time or on the object will arise

    the acceleration

  • 8/11/2019 Teaching Physics I

    19/28

    The number of force that affect the objects or total force can be either single or

    combined Force

    Influence on accelerating force

    The acceleration experienced by the objects is proportional to the resultant force acting

    on the object, and in line with the direction of the force

    In everyday life, we often hear the Word forces as a way, for example, the force of

    speech, force of dress, force of swimming, lifeforce, and more. What is the sense of

    force in everyday life with the same sense of force in physics? Note image di aside.

    Paratroopers can down because an grafity force. Other examples include forces in

    physics is someone pushing a car with a muscular force, using a bicycle in motion then

    otor di brake until it stops due to friction. So what is the sense of force according to

    physics?

    Based on by way of example a force in physics can be defined as:

    force is an amount that can cause something this stuff can move or otherwise

    cause moving objects become silent

    or briefly, force also can be defined as impulse or pull.

    By virtue of nature, the differentiated into 2 namely: Force touch , Force not touch By

    Caused, the differentiated into 7, namely: Force Muscle

    Force Springiness

    Force Friction

    Force Magnetism

    Force Electric

    Force Grafity

    Force Machine

    2. Resultan Force

    Some of the forces acting on an object in the line of work can be replaced by a

    force called force.

    Mathematically, the magnitude of the resultant force can be expressed as follows

    To simplify the calculations, give positive sign () to force the direction to the

    right or upwards and the negative (-) sign to force him to the left or down.

    Example:

    Andi and Bob play tug of war. If Andi grant Force 40 N while Budi give Force 45 N,

    what is the resultant force acting on the ropes?

    Solution:

    = 40 N45 N

    = - 5 N

    The negative sign indicates the rope moves to the left.

    3. Weight Force

    The weight of an object is the gravitational force acting on an object. Weight including

    force, therefore it has direction and weight including the vector quantity. The weight of

    the object toward the center of the Earth.

    The weight of an object can change depending on the magnitude of gravity. The

    magnitude of gravity depends on the height of the layout of an object from the

    pemukaan the Earth. The higher the position of the objects from the surface of the

    Earth, then the less gravity. A unit of weight expressed in units of

    newton.Mathematizable can be written:

    Example:

    An astronauts went to the moon. The mass of the astronaut is 65 kg. How much does it

    weigh when di Earth and how much it weighs when di Moon (Earth's gravity = 9.8

    N/kg, the gravity of the Moon = 1.6 N/kg).

  • 8/11/2019 Teaching Physics I

    25/28

    Solution:

    Weight on Earth: w= m g

    = 65 kg x 9,8 N/kg

    = 637 N

    Weight on Moon: w = m g

    = 65 kg x 1,6 N/kg

    = 104 N

    4. Newtons Law

    Around the 17th century an original United Kingdom scientists named Sir Isaac Newton

    to investigate about the force and movement. From the results of investigations and

    experiments he posited three opinions known as the law of Newton, Newton's Law II,

    and III the law of Newton. The following will be the third such law explained:

    1. Newtons I Law

    In ancient times, people believe that this nature is moving by itself. Isn't there

    something else moving it. They call it with natural motion. On the other hand, for

    objects that clearly driven, they named the forced motion. Theory pioneered by

    Aristotle is proven wrong when Galileo and Newton put forward their opinions.

    Galileo's theory of Aristotle to break a simple experiment. He made a slick curved path

    that is used to roll a ball. One side of the path to its personalised way. After observing,

    Galileo declared If friction on the object is removed, then the object will keep moving

    without requiring a longer force.

    Galileo's theory was developed by Isaac Newton. Newton says that If the resultant

    force on an object is equal to zero, then the object will remain stationary and moving

    objects will keep moving with constant velocity. Newton's conclusion is known as

    Newton's law. Mathematically can be written as follows.

    Based on Newton's law, You have to understand that an object tends to defend the case.

    Objects are initially silent will maintain a State of silence, and the first move will

    maintain the movements. Therefore, the law of Newton is also often referred to as the

    law of kelembaman or the law of inertia. Measure the quantity of a body's mass is

    kelembaman. Each object has a different level of kelembaman. The greater the mass of

    an object, the greater the kelembamannya. While driving a motorcycle you can directly

    acquire great velocity in a short time. However, when you take the train, certainly

    require a longer time to achieve great speed. It happened because the train has a mass

    greater than the mass of the motorcycle.

    2. Newtons II Law

    Newton's first law only covers items that are not subject to force from the outside,

    meaning that objects are not accelerating. What if an object gets the force from the

    outside or on the object to work multiple forces that resultannya is not equal to zero? In

    this condition, the acceleration of the object is changed. The relationship between

    acceleration, force, and mass was first propounded by Newton. The statement made it

    known to the law of Newton's II. As for the sound of Newton's Law II are as follows

    Objects having a force will gain a large acceleration is directly proportional to the

    number of his force and the relation to the upside against the masses

    mathematically can be written:

    Example

    A truck can generate a force of 7,000 n. If the truck can move with the acceleration of

    3.5 m/s, then determine the mass of the truck

    Given : = 7.000 N

    a = 3,5 m/s

    m=F/a=(7000 N)/(3,5 m/s)

    = 2.000 kg = 2 ton

    So mass truck is two tons.

    3. Newtons III Law

    If you play the Board, that ye may be able to slide forward so you guys should

    emphasize one of kai jalasn to you guys while the other remains di skateboard. Foot

    pressure you guys give force action on the road while the road held a reaction force

    opposite the direction the direction of the force of the foot action you guys. Thus the

    Board can slide forward. Such events demonstrate the application of Newton's Law III.

    As for the sound of Law III of Newton is

    If an object does the force (action) on other objects, it will arise from the reactions of

    a body force of the terhadapa objects of the same size, while the opposite direction

    mathematically can be written

    Experiment

    A. Goal

    Investigate the influence of the force and the mass of the object's acceleration

    B. Tools

    Repeat step two with a load of plus

    Compare the results of the second and third steps, make conclusions

    Repeat step two with the added load on Board slide

    Compare the results of the second and fifth steps, make the conclusion
