Momentum, Impulse, and Collisions

Front

What type of collision is characterized by the conservation of momentum but not kinetic energy?

Back

Inelastic collision.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

What is the momentum of an object with a mass of 10 kg moving at a velocity of 3 m/s?

Back

30 kg m/s.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.

Front

What is the relationship between impulse and momentum?

Back

Impulse equals the change in momentum (Impulse = Δp).

Front

What happens to momentum in a perfectly elastic collision?

Back

Both momentum and kinetic energy are conserved.

Front

What is the momentum of a 5 kg object moving at 4 m/s?

Back

20 kg m/s.

Front

In which type of collision is kinetic energy conserved?

Back

Elastic collision.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before a collision equals the total momentum after the collision.

Front

If two objects collide and stick together, what type of collision is this?

Back

Perfectly inelastic collision.
