The unit scientists express force.
What is a newton?
100
The distance traveled divided by the time interval during which the motion occured.
What is Speed?

What is a lubricant?
200
The measure of amount of matter in an object.
What is mass?

The combination of all of the forces acting on an object.

What is net force?

200
Total distance divided by total time.
What is the formula to find average speed of an object?
200
Mass times the velocity.
What is the equation to find momentum?
300
A force that is applied to an object but does not cause the object to move.
What is static friction?
300
A measure of the gravitational forceexerted on an object; its value can change with the location of the object in the universe.
What is weight?
300
Force is simply a _____ or a ______.
What is a push or a pull?
300
The rate at which velocity changes over time; an object accelerates if its speed, direction, or both change.
What is acceleration?
300
Any time objects collide, the total amount of momentum stays the same.
What is the law of conservation of momentum?
400
Friction between two moving surfaces.
What is kinetic friction?
400
This man made the law of universal gravitation.This is measured in grams.
What is mass?
400
When forces on an object produce a net force of 0 N.
What is balanced forces?
400
final velocity minus starting velocity divided by the time it takes to change velocity.
What is the formula to find the average acceleration of an object?
400
When a moving object hits another object, some or all of the momentum of the first object is transferred to the object that is hit.
What is the Law of Conversation of Momentum?

This man made the law of universal gravitation.
Who is Sir Isaac Newton?
500
When the forces on an objest don't become 0 N.
What is unbalanced forces?
500
The speed of an object in a paticular direction.
What is velocity?
