Definition
Motions
Term
what is the measure of how far an object moved?
Definition
Distance
Term
what is the distance an object has moved and the direction an object has moved in position from the starting point?
Definition
Displacement
Term
This must be specified in order to determine if an object has changed position.
Definition

Velocity
Term
What occurs when an object changes speed or changes it's direction?
Definition
Acceleration occurs
Term
An object speeds up if it's acceleration is
Definition
in the same direction of it's motion
Term
An object slows down if its acceleration is
Definition
in the opposite direction of its motion
Term
The Equation for Acceleration is
Definition
Final Velocity - First Velocity / The amount of Time taken
Term
What is Force
Definition
Force is a push or a pull

Term
What is Inertia
Definition
the resistance of an object to a change in motion.
Term
What is Newton's First Law of Motion
Definition
The motion of an object won't change unless an unbalanced net force acts on it.
Term
What is Acceleration
Definition
The rate at which the Veolocity (Speed and direction) of an object changes.
Term
What is Instantaneous Speed
Definition
The speed at a given point in time.
Term
What is Velocity
Definition
