Momentum and Collisions conceptual

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

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

Front

What happens to momentum in an elastic collision?

Back

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

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

Front

How does mass affect momentum?

Back

For a given velocity, an increase in mass results in an increase in momentum.

Front

How does velocity affect momentum?

Back

For a given mass, an increase in velocity results in an increase in momentum.

Front

What is an inelastic collision?

Back

An inelastic collision is one in which momentum is conserved, but kinetic energy is not.

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

Back

It is an inelastic collision.

Front

What effect does increasing the time of impact have on force during a collision?

Back

Increasing the time of impact decreases the force experienced during the collision, assuming the change in momentum remains constant.
