Momentum and Newton's Law of Motion

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the equation p = m*v.

Front

What is the formula for calculating momentum?

Back

p = m*v, where p is momentum, m is mass, and v is velocity.

Front

What is the Law of Conservation of Momentum?

Back

The Law of Conservation of Momentum states that the total momentum of a closed system remains constant if no external forces act on it.

Front

How do you calculate the momentum of an object?

Back

Momentum is calculated by multiplying the mass of the object by its velocity (p = m*v).

Front

If an object has a mass of 10 kg and is moving at a velocity of 3 m/s, what is its momentum?

Back

p = m*v = 10 kg * 3 m/s = 30 kg∙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.

Front

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

Back

This is called a perfectly inelastic collision.

Front

What is the relationship between mass, velocity, and momentum?

Back

Momentum is directly proportional to both mass and velocity; increasing either will increase momentum.

Front

How does increasing the mass of an object affect its momentum if velocity remains constant?

Back

If the mass increases while velocity remains constant, the momentum will increase.
