Momentum and Impulse

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

What factors affect the momentum of an object?

Back

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

Front

What are the standard metric units of momentum?

Back

The standard metric units of momentum are kilograms meter per second (kg m/s).

Front

What happens to the momentum of two objects that collide and stick together?

Back

The total momentum before the collision is conserved, but the individual velocities of the objects will decrease after the collision.

Front

How do you calculate the momentum of an object?

Back

Momentum is calculated using the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

If a runner has a momentum of 670 kg m/s and is traveling at a velocity of 9 m/s, what is his mass?

Back

The mass of the runner is 74.4 kg, calculated using the formula m = p/v.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, represented by the formula J = FΔt, where J is impulse, F is force, and Δt is the time duration.

Front

How is impulse related to momentum?

Back

Impulse is equal to the change in momentum of an object, expressed as J = Δp.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before and after an event (like a collision) remains constant.

Front

What is the formula for calculating impulse?

Back

Impulse can be calculated using the formula J = FΔt, where J is impulse, F is the average force applied, and Δt is the time duration.
