What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, an object at a height has gravitational potential energy.

Front

Where is maximum kinetic energy found on a roller coaster?

Back

At the bottom of a big hill.

Front

Do prokaryotes have a nucleus?

Back

No, prokaryotes do not have a nucleus.

Front

How do you calculate density?

Back

Density is calculated by dividing the mass of an object by its volume (Density = Mass/Volume).

Front

What is the density of an object with a mass of 27 g and a volume of 3 mL?

Back

9 g/mL.

Front

What is the density of an object with a mass of 25 g and a volume of 5 mL?

Back

5 g/mL.

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy = mass × gravity × height (PE = mgh).

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.

Front

What happens to potential energy as an object falls?

Back

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