Energy and Waves Final Review

Front

Energy conversion as a boy pedals a tricycle:

Back

The boy's stored energy converts to the tricycle's kinetic energy.

Front

Kinetic energy ranking of bicycles (greatest to least): Mountain bike 1, Mountain bike 2, Road bike 1, Road bike 2.

Back

Correct answer: Mountain bike 1, Mountain bike 2, Road bike 1, Road bike 2.

Front

Relationship between kinetic energy and race car speed:

Back

As speed increases, kinetic energy increases and the rate of change increases.

Front

A student throws a ball with his left hand, catches it with his right. When the ball is above his hand but not yet over his head, which energy changes occur?

Back

Potential energy increases while kinetic energy decreases.

Front

When a ball is directly above a student's head after being thrown, what is true?

Back

Kinetic energy is zero; potential energy is at its maximum.

Front

A student throws a ball with her left hand, catches it with her right. When the ball descends, which energy changes occur?

Back

Kinetic energy increases while potential energy decreases.

Front

Energy change of a cart moving down a hill:

Back

Potential energy converts to kinetic energy.

Front

Carpenter needs data to calculate work lifting tools:

Back

Height and amount of force.

Front

Energy transformation in Miguel's spring test:

Back

Elastic potential energy from the spring transformed into kinetic energy of the ball.
