EFFECTS OF FORCE

By Samyukta Satheesh

WHAT IS FORCE ?A force is any influence that causes an object to

undergo a certain change, either concerning its movement, direction, or geometrical construction. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or a flexible object to deform, or both. Force can also be described by intuitive concepts such as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton's and represented by the symbol F.

TYPES OF FORCE

ELETRICAL FORCE FRICTIONAL FORCE MAGNETIC FORCE GRAVITATIONAL FORCE MECHANICAL FORCE

FRICTIONAL FORCE What is frictional force?

Frictional force is present everywhere in our daily life .

What causes frictional force?

The force of friction is ultimately the result of forces

between atoms of the two constituent objects that are

touching.

ELECTRICAL FORCE WHAT IS ELECTRICAL FORCE?

Electric force is the force that is created by the magnitude of the various charges on each of the

various forces involved in the process.

MAGNETIC FORCE A magnetic force is a type of field force whose

potential and momentum energy is at the expense of an electrical field in time. It can be observed when a magnetized metal comes into contact with to another magnetized material. This force is usually measured in Newton's and its direction is given by the right hand rule.

GRAVITATIONAL FORCE The force of attraction between all masses in the

universe; especially the attraction of the earth's mass for bodies near its surface; "the more remote the body the less the gravity"; "the gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them“.

MECHANICAL FORCE The force exerted by machines is called

mechanical force.

EFFECTS OF FRICTIONAL FORCE.

Think about what happens if you rub your hands together. If you press your hands together, you have to push harder to slide your hands past each other, and your hands heat up more quickly. Pressing your hands together is like adding more weight to the box before trying to slide it across the floor. The added weight makes the box push down harder on the floor, and you will have to push harder on the box to make it slide.

Think about what happens if you rub your hands against a smooth, polished surface, like wood furniture, compared to a surface with a rougher texture, like denim cloth. Which surface produces more kinetic friction?

EFFECTS OF ELECTRICAL FORCE We certainly feel the electrical effects when there

is a large accumulation of charge, like when we get a shock or get hit by lightning.

The electromagnetic force is what holds atoms together and binds them together to make solids. So in a sense every time we touch anything, we are feeling the electromagnetic force. It is that force that makes solids feel solid, specifically the repulsion between the electrons in our body and the electrons in the object.

EFFECTS MAGNETIC FORCE

EFFECTS OF GRAVITATIONAL FORCE If you pull an object vertically, work is

done to against the gravity force. However, if you pull the same object horizontally, work is done to against the friction between the object and the horizontal surface e.g. table, or ground floor. Thus, as you mentioned, the energy you spend on pulling the object "x" and 'y" are not equal.
