Momentum and the Law of Conservation of Momentum

Front

What is momentum?

Back

Momentum is a measure of the motion of an object, calculated as the product of its mass and velocity.

How is momentum calculated?

Back

Momentum (p) is calculated using the formula: p = mass (m) × velocity (v).

Front

What does the Law of Conservation of Momentum state?

Back

The Law of Conservation of Momentum states that in a closed system, the total momentum before and after a collision remains constant.

Front

What factors affect the momentum of an object?

Back

The momentum of an object depends on its mass and velocity.

Front

If an object has a large mass but is moving slowly, how does its momentum compare to a small mass moving quickly?

Back

The object with the larger mass may have greater momentum, depending on the specific values of mass and velocity.

Front

What happens to the momentum of two colliding objects?

Back

The total momentum of the two objects before the collision is equal to the total momentum after the collision.

Front

Can momentum be lost in a collision?

Back

No, according to the Law of Conservation of Momentum, momentum is neither lost nor gained in a closed system.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg·m/s).

Front

In a collision, if one object is stationary, how does it affect the momentum of the moving object?

Back

The momentum of the moving object will be transferred to the stationary object, resulting in a change in their velocities.

What is an example of a real-life application of momentum?

Back

A car crash is an example where momentum is transferred between vehicles, affecting their motion.
