Term
 velocity
Definition
 a vector quantity of speed with a direction (can be positive and negative) Equations: v = d/t vf2 = vi2 + 2ad vf = vi + at
Term
 Time
Definition
 a duration (change) measured in seconds (s) Δt = (tfinal-tinitial) is the change of time
Term
 Newton Laws Of Motion: First Law
Definition
 an object in motion will stay in motion unless an unbalanced force acts on it, and  an object at rest will stay at rest unless an unbalanced force acts upon it
Term
 Acceleration
Definition
 The rate at which velocity is changing. this is also a vector quantity so it has both magnitude and direction.  a=(vf-vi)/t
Term
 Newton Laws of Motion: Second Law
Definition
 F=ma
Term
 Newton Laws of Motion: Third Law
Definition
 every action has an equal and opposite reaction
Term
 Vector Quanties
Definition
 quantities that have a magnitude and direction, the direction is typically denoted with a sign.
Term
 Law of Inertia
Definition
 the tendency for an object to remain in motion or rest
Term
 Inertia
Definition
 porportional to mass
Term
 Gravitational Acceleration
Definition
 an acceleration due to earths gravitaional pull which is always 9.8 m/s2 (or 10 m/s2)
Term
 Displacement
Definition
 displacement is the measure of the distance between the final postion and the original position. Displacement is a vector sum.
Term
 Distance
Definition
 the total distance traveled
Term
 Simple Harmonic Motion
Definition
 a oscillating pattern the two most common examples of which are a pendulum and spring occilations
