Front

What transformation of energy occurs when food is converted to energy for movement?

Back

The transformation is from chemical energy to mechanical energy.

Front

What is the relationship between mass and stopping distance?

Back

A car with a larger mass will require more force to stop than a car with a smaller mass, assuming both are traveling at the same speed.

Front

What are tides?

Back

Tides are the rise and fall of sea levels caused by the gravitational forces exerted by the moon and the sun.

Front

What is a warm front?

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food, which can be converted into other forms of energy.
