Energy Transformations practice

Front

What is the Law of Conservation of Energy?

Back

Energy cannot be created or destroyed, only transformed.

Front

What two factors determine kinetic energy?

Back

Kinetic energy depends on mass and speed.

Front

What happens to potential and kinetic energy in a swinging pendulum?

Back

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

Front

What is an example of potential energy?

Back

A stretched rubber band.

Front

What type of energy does a ball have when held at the top of a hill?

Back

Potential energy.

Front

What is kinetic energy?

Back

The energy of an object in motion.

Front

What is potential energy?

Back

The stored energy of an object due to its position or state.

Front

How is energy transformed in a roller coaster?

Back

Potential energy is converted to kinetic energy as the coaster descends.

Front

What is an example of energy transformation in a light bulb?

Back

Electrical energy is transformed into light and thermal energy.

Front

What is the formula for kinetic energy?

Back

Kinetic energy = 1/2 * mass * speed^2.
