Speed
Measure how fast an object moves
Velocity
Speed with direction
Acceleration
Is velocity change during a certain period of time
True or false if there isn’t an exponent on something it is acceleration
False
Force
Physical action/movement
Applied force
Force which is applied to an object by another object
Motion
Time of the position
Magnitude
Extent of something
Gravitational force
The force of attraction
Frame of reference
Measurements made
Radial acceleration
In a circular motion
Direction
A course where someone moves
Net force
Forces acting on an object
Balanced force
Equal in size
Average speed
Overall speed
Newtons
Unit of force
Friction
Something rough
Unbalanced force
The force applied in one direction is greater than the force applied in the opposite direction
Constant speed
Speed remains the same
Normal force
Contact force
frictionless
A smooth object
acceleration
Gain speed in a short amount of time
Constant velocity
Constant speed in a constant direction
Deceleration/negative acceleration
Reduction in speed or rate
