Q. 3 B4.3( 20 Votes )

A. An object of mass 2 kg moving with uniform velocity of 2 ms-1.

Explanation: Momentum is defined as the product of the mass and the velocity of the object, i.e. Where p is momentum of the object and m, v represents mass and the velocity respectively.

Case 1: Information from the question:

Mass of the object = 2 kg

Velocity of the object = 2 ms-1

Hence for momentum,

Momentum of an object = mass × velocity

= 2 × 2

= 4 kg ms-1

Case 2: Information from the question:

Mass of the object = 1 kg

Velocity of the object =3 ms-1

Hence for momentum,

Momentum of an object= mass × velocity

= 1 × 3

= 3 kg ms-1

Now, momentum in Case 1 is more than in Case 2. Hence we can observe that momentum is quantity which depends on both mass as well as velocity of the object.
