Unit 2 Review - SCI8

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What happens to Thermal Energy when two objects reach the same temperature?

Back

Thermal energy stops moving between the objects when they have the same temperature.

Front

What increases when temperature increases?

Back

Kinetic energy increases when temperature increases.

Front

What is the energy transformation when burning a log?

Back

The energy transformation is from chemical energy to thermal energy.

Front

What two factors does Thermal Energy depend on?

Back

Thermal Energy depends on Mass and Temperature.

Front

Define Kinetic Energy.

Back

Kinetic Energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the particles in a substance also increases.

Front

What is an example of Gravitational Potential Energy?

Back

An example of Gravitational Potential Energy is a book placed on a shelf. The higher the shelf, the more potential energy the book has.

Front

What is the difference between Thermal Energy and Temperature?

Back

Thermal Energy is the total energy of all particles in a substance, while Temperature is a measure of the average kinetic energy of those particles.

Front

What is Chemical Energy?

Back

Chemical Energy is the energy stored in the bonds of chemical compounds, like food or fuel.
