Energy REVIEW

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its position in a gravitational field, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What happens to potential energy as a pendulum swings down?

Back

As a pendulum swings down, its potential energy decreases while its kinetic energy increases.

Front

What is the highest point of a rollercoaster known for?

Back

The highest point of a rollercoaster has the most gravitational potential energy.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

What is the initial state of energy in a stretched rubber band?

Back

The initial state of energy in a stretched rubber band is elastic potential energy.

Front

What type of energy does wood have before it is lit on fire?

Back

Before it is lit, wood has chemical potential energy.

Front

What happens to kinetic energy at the lowest point of a swing?

Back

At the lowest point of a swing, kinetic energy is at its maximum.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh.
