Physical Science Review

Energy of motion or MOVEMENT

​

Example: A ball that is rolling down the hill​

Kinetic Energy

Energy that is STORED in ​an object

​

Example: A ball sitting at the top of the hill​

Potential Energy

eNERGY IS THE ABILITY TO DO WORK

Work is a force that moves an object

​

Sources of energy that cause movement:

• wind and water​

Some text here about the topic of discussion

A force is a push or a pull

Forces are always acting on an object.

• Gravity, the force of the ground, friction, etc.

​

When an object is moving, the forces are UNBALANCED​.

Slow the flow of thermal energy and electricity between objects

​

ie., thick fabrics, rubber, glass, plastic​

Insulators

Allow thermal energy and electricity to flow easily between objects

​

ie., METAL​

Conductors

The path the electricity can travel through is not complete, so the electricity cannot flow back to the power source.​

Open circuit

The path that the electricity can travelled in has no breaks. Electricity will flow from the power source to the lightbulb then back to the power source

Closed circuit
