Term
Acceleration
Definition
the rate at which velocity changes, (increasing speed, decreasing speed, or change in direction.)
Term
Motion
Definition
the state in which one objects distance is changing from another object.
Term
Reference Point
Definition
a place or object used for comparison to determine if something is in motion.
Term
Speed
Definition
the distance the object travels in one unit of time.
Term
Velocity
Definition
speed in a given direction.
Term
Force
Definition
a push or pull on an object.
Term
Net force
Definition
the overall force acting on an object.
Term
Unbalanced force
Definition
When a net force changes an object's motion it is said to be unbalanced.
Term
Balanced force
Definition
equal forces acting on one object in opposite directions.
Term
Motion is graphed with a ___________________graph
Definition
Line graph
Term
__________________ is labeled on the x-axis (horizontal).
Definition
Time
Term
_________________________ is graphed on the y-axis (vertical).
Definition
Distance
Term
An object at rest will remain at rest or an object in motion will remain in motion unless an outside force acts on it.
Definition
Newton's First Law of Motion
Term
The force of an object is equal to it’s mass times its acceleration. F = M x A
Definition
Newton's Second Law of Motion
Term
For every action there is an equal and opposite reaction.
Definition
