Question

Explain Newton's First & Second Law of Motion (in simple words)

Answer 1

First Law of Motion:

It means that a moving object will try to stay at motion, while a stopped object will try to stay at rest. It is also called inertia.

E.g. If you are standing in a bus and it suddenly starts moving, you tend to fall backwards. This is because our legs along with bus starts moving but the upper part of our body tends to stay at the place it was while trying to stay at rest.

The vice-versa happens if the bus stops suddenly.

Second Law of Motion:

The second law of motion states that to every force, there is an equal and opposite force. This means that if you are applying force on an object, that object applies an equal force but in the opposite direction that the direction the initial force occured.
