According to Newton's second law...

Acceleration is produced when a force acts on a mass. The greater the

mass (of the object being accelerated) the greater

the amount of force needed (to accelerate the

object).

What does this mean?

Everyone unconsiously knows the Second Law. Everyone knows that

heavier objects require more force to move the same distance as lighter

objects.

However, the Second Law gives us an exact

relationship between force, mass, and acceleration. It

can be expressed as a mathematical equation: 

orFORCE = MASS times ACCELERATION

This is an example of how Newton's Second Law works:

Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Using Newton's Second Law, you can compute how much force Mike is applying to the car.

Answer:

50 newtons

Newton's second law of motion explains how an object will change velocity if it is pushed or pulled upon.

Firstly, this law states that if you do place a force on an object, it will accelerate (change its velocity), and it will change its velocity in the direction of the force. So, a force aimed in a positive direction will create a positive change in velocity (a positive acceleration). And a force aimed in a negative direction will create a negative change in velocity (a negative acceleration). 

Secondly, this acceleration is directly proportional to the force.

For example, if you are pushing on an object, causing it to accelerate,

and then you push, say, three times harder, the acceleration will

be three times greater.

the direct proportion between force and acceleration The masses, or objects, are the yellow rectangles. All of the masses are the same. So

this demonstration does not consider any change in mass. The mass is constant. The applied net forces are the red arrows. The forces are not the same. The one at the

top is the biggest, the one at the bottom is the smallest, and the one in the middle is medium sized.

All of the objects accelerate. The velocity in each case gets greater and greater. That is, the speed increases. However, the three accelerations are not all the same. Every one speeds up, but they speed up differently.

The acceleration at the top is the largest acceleration. The velocity changes by the largest amount per second here. Note that the largest force is applied to this mass. So the largest force has the largest acceleration.

The acceleration at the bottom is the smallest acceleration. Here the velocity changes by the smallest amount per second. Also, here we have the smallest force. So the smallest applied force creates the smallest acceleration.

the inverse proportion between acceleration and massThe applied net forces are the red arrows. In each case the force is the same. There

is no consideration for changes in force in this demonstration. The applied net force is constant.The yellow boxes are the masses. Although all the yellow boxes have the same size, they do not all represent the same mass. The mass is different in each case. Note the labels. The one at the top is the smallest mass, m. The one at the bottom is the largest, 3m, or three times the top mass. The one in the middle is twice as massive as the one at the top.All of the objects accelerate. The velocity in each case gets greater and greater. That is, the speed increases. However, the three accelerations are not all the same. All the objects are speeding up; it's the way they are speeding up that is different.The acceleration at the top is the largest acceleration. The velocity changes by the greatest amount per second here. Note that here we have the smallest mass. So the smallest mass has the largest acceleration.The acceleration at the bottom is the smallest acceleration. Here the velocity changes by the least amount per second. Also, here we have the biggest mass. So the biggest mass has the smallest acceleration.
