​Force and Motions Terms

Force: ​Push or Pull on an object.

​

​

Gravity: The pull towards the center of the Earth.

​

​

​

​Friction: Invisible push that slows objects down or stops objects.

​

​

Multiple Choice

What is a force?

• Accelerates Forward

• Slows down and stops

• Pull toward the Earth

• Push or Pull

Multiple Choice

• Force

• Gravity

• Friction

• Motion

Multiple Choice

What would cause the car to stop when going down the ramp?

• Gravity

• Force

• Friction

Multiple Choice

If I was to do an experiment with different sized magnets and paper clips,

what am I testing? Choose the best answer.

• How conductive the magnets are

• How gravity affects the magnet

• How strong the pull of the magnet is

• How friction affects the magnet

Multiple Choice

Which magnet has the greatest pull?

​Circuits

A circuit is the path an electric current flows.

​

For a circuit to work, there must be a complete path and the switch must be closed.

​

If the light is on, the circuit is closed.

​

If the light is off, the circuit is open. ​

​

A complete circuit must have a complete path and have a battery or power source. ​

​Conductors vs Insulators

Conductors:

Materials that allow electric currents to pass through with little or no resistance.

​Ex: Wires

​

Insulators:

Materials that do not allow electrons to pass through ​

​Ex: Plastic Wire Covering
