All Newton’s Laws of Motion [Explained with Example]

What are Newton's Laws of Motion? [Explained with Example]

Newton’s laws of motion is all about understanding the motion of an object and the forces acting on it.

Here’s a quick overview on 3 newton’s laws of motion:

  1. Newton’s first law explains that objects will continue doing what they are doing, unless an unbalanced force acts on them.
  1. Newton’s second law explains about the acceleration of an object.
  1. Newton’s third law explains about the action and reaction forces acting on an object.

Not understood properly?

Don’t worry. I’ll make it easy for you.

Let’s consider one simple example to understand the above definitions properly.

Newton’s Laws Example

Consider a ball lying on the floor.

Newton's laws example - Ball moving on the floor

First law of motion says that…

Object’s (whether in rest or motion) do not change their behaviour, unless an unbalanced force acts on them.

Example of newton's law - Ball moving on the floor

Second law of motion says that…

Acceleration is directly proportional to net force applied and inversely proportional to mass of an object.

More the force applied on a ball, the more it will accelerate.

Similarly,

More the mass a ball has, the less it will accelerate.

Newton's law explained - Ball resting on the floor

Third law of motion says that…

To every action, there is always an equal and opposite reaction

Note that the action and reaction forces are acting on two different bodies. (i.e., Ball and Floor)

Summary

From the above example, one thing is understood.

According to newton’s first law…

Object’s (whether in rest or in motion) do not change their behaviour, unless an unbalanced force acts on them.

According to newton’s second law…

More the force applied on an object, the more it will accelerate.

Similarly,

More the mass an object has, the less it will accelerate.

According to newton’s third law…

If there is an action, then there is always an equal and opposite reaction.
