Week 16 - Potential and Kinetic Energy

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like wood, batteries, gasoline, and food.

Front

Which type of energy is stored when a spring is compressed?

Back

Elastic potential energy is stored when a spring is compressed.

Front

What happens to kinetic energy as the speed of an object increases?

Back

The kinetic energy increases as the speed of an object increases.

Front

What is the relationship between potential energy and height?

Back

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

Front

What is kinetic energy?

Back

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

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; a heavier object moving at the same speed has more kinetic energy than a lighter object.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height.

Front

What is an example of a situation where potential energy is converted to kinetic energy?

Back

When a roller coaster descends from a height, its potential energy is converted into kinetic energy as it speeds up.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy is present in a stretched rubber band?

Back

A stretched rubber band contains elastic potential energy.
