100
An object that appears to stay in place.
What is reference point?
100
This is a force of attraction between objects because of their masses.
What is gravity.
100
Used to tell when something or someone is in motion.
What is a reference point?
100
A force that opposes motion between two surfaces that are in contact.
What is Friction?
100
You wear gloves that have more grip so you can hold onto stuff.
How do you increase friction?
200
The place where someone or something is in relation to other objects.
What is position?
200
Does the moon have more or less gravity?
What is less gravity.
200
an objects change in position relative to a reference point.
What is motion.
200
When a force is applied to an object but it doesn't move.
What is Static Friction?

What is Speed?
400
It causes rug burns.

400
The combination of all of the forces acting on an object.
What is Net Force?
500
The speed of an object in a specific direction.
What is velocity.
500
The force between objects decrease as the distance between objects increases. Name this force!
What is gravitational force.
500
Sir Isaac Newton.
What is the name of the scientist that defined the Law of Universal Gravitation.
500
It can stop cars from moving.
How is Friction good?
500
a push or pull exerted on an object in order to change the motion of the object: force has size and direction.
