Conservation of 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.

Front

How does mass affect momentum?

Back

An object's momentum increases with its mass if its velocity remains constant. A heavier object has more momentum than a lighter object moving at the same speed.

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 have the same velocity, which has more momentum?

Back

The object with greater mass has more momentum.

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 a collision remains constant.

Front

Calculate the momentum of a 5 kg object moving at 2 m/s.

Back

10 kg*m/s (p = mv = 5 kg * 2 m/s).

Front

What happens to momentum in a perfectly elastic collision?

Back

In a perfectly elastic collision, both momentum and kinetic energy are conserved.

Front

What happens to momentum in an inelastic collision?

Back

In an inelastic collision, momentum is conserved, but kinetic energy is not conserved.

Front

If a 10 kg object is moving at 3 m/s, what is its momentum?

Back

30 kg*m/s (p = mv = 10 kg * 3 m/s).

Front

What is the total momentum of two objects with masses 3 kg and 5 kg moving at 4 m/s and 2 m/s respectively?

Back

26 kg*m/s (p_total = p1 + p2 = (3 kg * 4 m/s) + (5 kg * 2 m/s)).
