8 - Lesson 28 and 30 Forms of Energy/PE in Systems

Front

What is the potential energy stored in a system of objects interacting by electric forces called?

Back

Electric potential energy (electric PE)

Front

What is the potential energy stored in a system of objects interacting due to gravitational forces called?

Back

Gravitational potential energy (gravitational PE)

Front

What is defined as the ability to cause motion or change?

Back

Energy

Front

What type of energy does an object have due to its motion?

Back

Kinetic energy

Front

What is the potential energy resulting from elastic forces called?

Back

Elastic potential energy (elastic PE)

Front

What is the formula for gravitational potential energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the difference between kinetic energy and potential energy?

Back

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

Front

What are the two main types of mechanical energy?

Back

Kinetic energy and potential energy.

Front

How does the law of conservation of energy relate to potential and kinetic energy?

Back

The total energy in a closed system remains constant; energy can transform between potential and kinetic forms but cannot be created or destroyed.

Front

What is an example of elastic potential energy in everyday life?

Back

A compressed spring or a stretched rubber band.
