Unit 3 Test Review

Front

What is the energy stored in an object due to its position called?

Back

Gravitational potential energy

Front

What term describes an up and down motion?

Back

Vertical

Front

What forces are at work when a yo-yo goes up and down the string?

Back

Friction opposes gravity and causes the yo-yo to move upward when there is a slight tug as it reaches the bottom of the string.

Front

Is a car at a stop sign considered to have potential or kinetic energy?

Back

Potential

Front

What is the term for a force that attracts or repels objects?

Back

Magnetism

Front

What is the formula for gravitational potential energy?

Back

PE = mgh (where PE is potential energy, m is mass, g is acceleration due to gravity, and h is height).

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

How does friction affect the motion of objects?

Back

Friction opposes the motion of objects, slowing them down or stopping them.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.
