The force F acting on a particle of mass m is indicated by the force-time graph as shown below. The climate change in momentum of the particle over the time interval from zero to 8 s is,

• 24 Ns

• 20 Ns

• 12 Ns

• 6 Ns

C.

12 Ns

The area under F-t graph gives change in momentum.

For 0 to 2 s,

For 2 to 4 sec,

For 4 to 8 sec,

So, total change in momentum for 0 to 8 sec is,

What is the most essential thing to study the motion of a body?

The most essential thing to study the motion is reference frame. Rest and motion are relative terms. It means that an object in one situation can be in rest but in another situation, the same object will be in motion.

Is absolute rest or absolute motion possible?

Absolute rest and absolute motion is not possible because there is no point in the universe which is at rest and can be taken as point of reference. The planet Earth is in continuous motion.
