A Force that opposes the motion of another object; making the object slow down and eventually stop
Friction
How difficult it will be to stop an object
Momentum
push or pull
Force
The mysterious force that makes everything fall down towards the Earth. Depends on distance and mass.
Law of Gravity
occurring continuously over a period of time
Constant
A comparison of an object's location on a map to other things on the map
Position
Is a measure of gravitational force between earth and an object
Weight
Resistance to change in motion (objects will do what they are doing until a force acts upon it)
Inertia
The length of a path between two points
Distance
the beginning
Origin
The force that pulls objects down towards Earth's surface
Gravity
The distance an object travels over a certain amount of time
Speed
Also known as Law of Inertia, An object at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
Newton's first law
speed in a given direction
Velocity
factor that is liable to vary or change.
Variables
The measure of the amount of matter in an object
Mass
UNEQUAL forces, do change speed or direction
Unbalanced Forces
The more force applied, the greater the acceleration, the greater the mass of an object, the less the acceleration
Newton's Second Law
the action or process of moving or being moved
Motion
determine (the amount or number of something) mathematically
calculate
Change in speed or direction
Acceleration
EQUAL forces, do not change speed or direction
Balanced Forces
Every action has an equal and opposite reaction
Newton's third law
not moving
Stationary
how difficult it will be to stop an object
Momentum
