Collisions

Front

What does the Law of Conservation of Momentum state?

Back

The amount of momentum in a system is the same before and after a collision.

Front

What happens to energy when you raise a ball higher before releasing it?

Back

It transfers more energy upon impact.

Front

According to Newton’s first law of motion, why do passengers move forward during a car collision?

Back

Because passengers will continue to move forward due to inertia.

Front

What are the two types of collisions?

Back

Elastic and inelastic.

Front

What type of collision occurs when pool balls bounce apart?

Back

Elastic collision.

Front

Define an elastic collision.

Back

A collision where both momentum and kinetic energy are conserved.

Front

Define an inelastic collision.

Back

A collision where momentum is conserved, but kinetic energy is not.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect momentum?

Back

Momentum is the product of mass and velocity; more mass means more momentum.

Front

What is the formula for momentum?

Back

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