What is the expression for momentum:

- Mass × acceleration
- Force × displacement
- Change of velocity / time
- Mass × velocity

Correct answer: 4. Mass × velocity

Explanation: Momentum is a fundamental concept in physics, representing the quantity of motion an object possesses. It is defined as the product of an object’s mass and its velocity. The expression for momentum is given by:

Momentum = Mass × Velocity

So, the correct option is “Change of velocity / time” doesn’t represent the expression for momentum. Instead, it’s a description of acceleration, which is the rate of change of velocity with respect to time.
