The resistence of an object to a change in the speed or the direction of its motion.

Inertia


The amount of matter in an object.

Mass


Any change in motion of an object.

Acceleration


An object at rest will remain at rest and object in motion will remain in motion unless acted upon by an outside force.

Netwon's 1st Law of Motion


A push or a pull.

Force


A force that resists motion between two objects in contact

Friction


The force that resists motion between two objects in contact.

Gravity


What is the rate of acceleration of gravity?

9.8 meters per second/2


Forces that are equal in size but opposite in direction.

Balance Forces


Forces that cause a change in the motion of an object.

Unbalanaced forces


Anything that has mass and takes up space.

Matter


1 Netwon = 1 Kg mass X 1 Meter/sec2.

Netwon


F = M x A
Force = Mass x Acceleration 
Netwon's 2nd Law of Motion


For every action there is an equal and opposite reaction.

Netwon's 3rd Law of Motion


How many grams in a Kilogram?

1000


What would happen to an object's acceleration if the forces applied to it increase?

It accelerates


Why is it difficult to run on ice?

Less Friction


How are acceleration, mass and inertia related?

The more mass, therefore the more inertia, the harder it is to accelerate that mass.


The force that pushes on something.

Action force


The force that pushes back.

Reaction force


The total of all the forces action on an object.

Net force


Any force that keeps an object moving in a circle.

Centipetal force


What is the formula for Acceleration?

Acceleration = Force/Mass


What is the formula for Mass?

Mass = Force/Acceleration


What is the change in position over time?

Motion


The resistance of an object to a change in speed or direction is called?

Newton's First law of motion


The change in velocity over time?

Acceleration


What is Momentum?

Momentum = Mass times Velocity or
P=MV 

A collision is a situation in which two objects in close contact transfer?

Energy and Momentum


When you push on a door, the door pushes back with an equal and opposite force. These two forces are known as?

Action / Reaction force pairs


The momentum of an object is the product of its...?

Mass and Velocity


What is the unit of force?

Newton


What is the unit for mass?

Kg


What is the unit for acceleration?

m/s/s
Mass divided by seconds squared
