Momentum and Collisions DN

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

What is an elastic collision?

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not conserved.

Front

How do you calculate total momentum before a collision?

Back

Total momentum before a collision is calculated by adding the momentum of all objects involved in the collision.

Front

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

Back

It is an inelastic collision.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before and after a collision remains constant.

Front

If two objects have the same mass, what can be said about their momentum if one is moving faster?

Back

The faster moving object has more 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 is the relationship between mass and momentum?

Back

Momentum is directly proportional to mass; as mass increases, momentum increases if velocity remains constant.

Front

What is the significance of the direction in momentum?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction; the direction of momentum is the same as the direction of velocity.
