FLASHCARD - PE/KE

Front

What does friction do to a skateboarder going up a ramp?

Back

Friction slows them down.

Front

Gravitational potential energy depends on the ________ of the object.

Back

Gravitational potential energy depends on the height (position) of the object.

Front

The faster an object moves, the ________ kinetic energy it has.

Back

The faster an object moves, the more kinetic energy it has.

Front

__________ is stored energy.

Back

Potential energy is stored energy.

Front

Which cart has a little less kinetic energy than cart C?

Back

Cart B has a little less kinetic energy than cart C.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; more mass means more kinetic energy at the same speed.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.
