# 290Constant Velocit

### 290 Constant Velocity

acceleration the change in velocity divided by time (a = Δv / Δt)
Average speed Average speed is a measure of the distance traveled in a given period of time;
Constant Does not change
Displacement The change in position of an object
Force An action exerted on a body in order to change the body’s state of rest or motion; has magnitude and direction; A Push or Pull
Frame of Reference A system for specifying the precise location of objects in space and time. An arbitrary set of axes with reference to which the position or motion of something is described or physical laws are formulated
Instantaneous speed the speed at a particular instant of time http://www.physicsclassroom.com/mmedia/kinema/trip.cfm
Magnitude Size of the measurement or quantity; how big
Motion An object’s change in position relative to a reference point
scalar physical quantity that has magnitude but no direction
speed scalar measurement of the rate of motion (s = Δd/Δt)
Speed The distance traveled divided by the time interval during which the motion occurred.
vector quantity that has both a magnitude and a direction; an arrow giving magnitude (by its size) and direction
Velocity The speed of an object in a particular direction
velocity vector quantity whose magnitude is an object's speed and whose direction is the object's direction of motion
