What is positive or negative.
100
When an apple fell from a tree and hit this Scientist in the head, he discovered Gravity.
Who is Sir Isaac Newton.
100

An object at rest will remain still unless one of these forces is applied to it.

Applied force, magnetism, gravity, static-electricity. 

100

A force that happens when on object touches another. Example - opening a door or shooting a basketball.

Contact Force

200

A force that attracts masses

What is Gravity 

200

When two charges or poles push apart.

What is repel/repulsion

200

Our weight is based on this force.

Gravity.
200

When an object is in motion, it is travelling in one direction. We can change the direction of the object in motion by applying a force to it.  In sports, it is common to use this type of force. 

Muscular Force/applied force/contact force.

200

A force that acts on an object without touching it. Example - when an apple falls from a tree

Non-Contact Force

300

A force that attracts.  It refers to the attraction to iron, nickel, and cobalt. This force can push or pull an object depending on its poles.

What is Magnetism 

300

When two charges or poles pull together.

What is Attract

300

There is no gravity in space. True or False. 

False. 

300

When an object slides over another object it starts to slow down because of this force. 

What is friction.

300

Hitting a hockey puck into the net is _____________

Contact Force

400

When animals use their muscles to move an object 

Muscular Force/applied

400

When objects repel or attract due to their electrical charge, it is called this.

What is Electrostatic Force.

400

Name 2 of the three main magnetic metals.

What are iron, nickel, and cobalt.

400

The magnitude of a vector arrow is shown by its ______?

What is size/length?

400

Water falling in a waterfall

Non-Contact force

500

The resistance of motion when two objects rub together. 

Friction

500
With Electrostatic and Magnetism, the push and pull effects are called this.

Repeal and attract.

500

When like poles are facing eachother, this type of effect occurs.

What is Repulsion/repel.

500

Name two types of friction and give an example of each.

Air resistance/drag---falling through the air

Kinetic friction-sliding down a slide (surfaces rubbing together).

500

2 answers required---Rubbing your feet on a carpet 

Attractive force when electrons jump from your negatively charged self to another object.

Friction--Contact force

Electrostatic---Non-Contact Force
