Question

Momentum is a measure of which quantity ?

• A. motion
• B. friction
• C. gravitation
• D. electric force

Answer 1

The correct option is A

motion

Step 1. Momentum:

1. Momentum is the measurement of motion.
2. Any moving object will have momentum.
3. According to physics, the object’s momentum equals mass times velocity.
4. Mathematically,

Momentum $\left(p\right)$= mass$\left(m\right)$ x velocity$\left(v\right)$.

Step 2. Explanation:

1. It is the quantity of motion and is compounded by the quantity of the matter that is moving and the velocity with which it moves.
2. Hence it is associated with motion.
3. Momentum is present in everything that is in motion. e.g If a bicycle and a car travel down the street at an equal velocity, the car will have the more momentum.
4. Momentum is a vector quantity.
5. Thus, momentum is the measure of motion.

Hence, the correct option is option A.
