Momentum Flashcard

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.

What is the Impulse-Momentum Theorem?

Back

The Impulse-Momentum Theorem states that the impulse applied to an object is equal to the change in momentum of that object. Mathematically, Impulse = Δp = FΔt.

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 an event (like a collision) is equal to the total momentum after the event.

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 × Time.

Front

What is a perfectly elastic collision?

Back

A perfectly elastic collision is one in which both momentum and kinetic energy are conserved. Objects bounce off each other without any loss of energy.

Front

What is a perfectly inelastic collision?

Back

A perfectly inelastic collision is one in which momentum is conserved, but kinetic energy is not. The colliding objects stick together after the collision.

Front

How do you calculate impulse?

Back

Impulse can be calculated using the formula Impulse = Change in momentum = Final momentum - Initial momentum.

Front

What is the formula for calculating momentum?

Back

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

Front

What happens to momentum in a closed system during a collision?

Back

In a closed system, the total momentum before the collision is equal to the total momentum after the collision.

Front

What is the relationship between force and impulse?

Back

Impulse is equal to the average force applied multiplied by the time duration over which the force is applied: Impulse = F × Δt.
