Momentum and Impulse

Front

What is impulse?

Back

Impulse is the product of the force applied to an object and the time duration over which the force is applied. It is equal to the change in momentum of the object.

Front

How is impulse related to momentum?

Back

Impulse is equal to the change in momentum of an object.

Front

What type of collision occurs when two objects collide and stick together?

Back

This is called an inelastic collision.

Front

What is the formula for calculating momentum?

Back

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

Front

If an object has a momentum of 30 kg m/s and ends with a momentum of 40 kg m/s, what is the impulse?

Back

The impulse is 10 N*s.

Front

What factors affect the momentum of an object?

Back

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

Front

Calculate the momentum of a 1000-kg car moving southward at 20 m/s.

Back

The momentum is 20000 kg*m/s south.

Front

What is an elastic collision?

Back

An elastic collision is a collision in which both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is a collision in which momentum is conserved, but kinetic energy is not.

Front

Define momentum.

Back

Momentum is a vector quantity defined as the product of an object's mass and its velocity.
