Forms of Energy and Energy Transformations (Includes Collisions)

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is energy transferred through in collisions?

Back

Contact Forces.

Front

What does the Law of Conservation of Energy state?

Back

Energy is never created nor destroyed; it is only transferred or transformed.

Front

What type of collision occurs when pool balls bounce apart?

Back

Elastic collision.

Front

True or False: Speed or mass increases lead to kinetic energy increases before a collision.

Back

True.

Front

Define kinetic energy.

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is an inelastic collision?

Back

A collision in which kinetic energy is not conserved, and objects may stick together.

Front

What is an elastic collision?

Back

A collision in which both momentum and kinetic energy are conserved.
