Momentum and Impulse Review

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

How does mass affect momentum?

Back

An object with greater mass will have more momentum if moving at the same velocity as a lighter object.

Front

What happens to momentum if the velocity of an object changes while its mass remains constant?

Back

If the velocity changes, the momentum of the object changes as well.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force x Time.

Front

How is impulse related to momentum?

Back

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

Front

What is the law of conservation of momentum?

Back

The law states that in a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.

Front

What is the formula for calculating momentum?

Back

The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

If two objects collide and stick together, how do you calculate their final velocity?

Back

Use the conservation of momentum: m1v1 + m2v2 = (m1 + m2)v_final.

Front

What is the effect of a larger mass on stopping distance?

Back

A larger mass results in more momentum, requiring a greater force and longer stopping distance.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration (F = ma).
