Physics fundamentals not clear? Read this!

Engineering Entrance , JEE Main , JEE Advanced , fundamentals of physics , academic

THE LAW OF INERTIA

The tendency of a body to continue in its state of rest or of uniform motion in a straight line even when some external unbalanced force is applied is called Inertia. Mass is the measure of Inertia of a body.

Inertia is of two types namely:-

1. Inertia of rest

2. Inertia of motion

MOMENTUM

The force which a body possess due to combined effect of mass and velocity is callled the Momentum. It is defined as the product of mass and velocity. It is denoted by p . p=m*v

SI unit of Momentum is Kgm/sec

NEWTONs LAWS OF MOTION:-

NEWTON,s FIRST LAW OF MOTION

It states that a body will continue in its state of rest or of Uniform Motion in a straight line unless compelled by some applied unbalanced force to change of rest or of Uniform motion.

NEWTON,s SECOND LAW OF MOTION

The rate of change of Momentum of a body is directly proportional to the applied unbalanced force and takes place in the same direction in which the force acts.

NEWTON,s THIRD LAW OF MOTION

To every action, There is an equal and opposite reaction.

So, can u now answer,

1. How do we walk?

2. Why the gun recoils?

3. why is it difficult to alk on a sandy beach?

4. Can u tell the SI unit of Force?

Hope its all clear?

Thank u!
