- acceleration
- the rate at which velocity(speed and direction) changes
- Relative Motion
- is movement in relation to a frame of reference
- vector
- a quantity that has magnitude and direction
- non linear graph
- a cure connects the data pts that are plotted
- velocity
- speed and direction in which an object is moving
- Frame of Reference
- a system of objects that are NOT MOVING with respect to one another
- which graph is a good way yo describe motion
- a distance time graph
- the slope of a speed time graph is
- acceleration
- distance
- the length of a path between two points
- acceleration is described changes in
- speed, direction
- instantaneous acceleration
- how fast a velocity is changing at a specific instant
- To describe motion accurately and completely you need
- a frame of reference
- constant acceleration
- a steady change in velocity
- velocity is a
- vector
- acceleration is a
- vector
- speed
- the ratio of the distance an object moves to the amount of time the object moves
- displacement
- the direction from the starting pt. and the length of a straight line from the starting pt to the ending pt.
- free fall
- the movement of an object toward Earth solely b/c of gravity
- instantaneous speed
- the speed at a particular instant
- deceleration
- an acceleration that slows an objects speed
- average speed
- the entire duration of the trip
- to add displacements you use
- vector addition
- linear graph
- displays straight line parts
