VOCABULARY – Motion - when an object changes it position Relative Motion - an object’s position change is described in terms of a reference point Energy - a force can set an object into motion, stop it, or change the speed or direction of the object’s motion Inertia - measures an object’s tendency to remain at rest or keep moving. More mass = more inertia Distance - the entire path an object travels Displacement – the distance and direction between starting and ending position. Example: You hiked 22 km over a mountain, but you only are 12 km from where you started. 22km is you distance - displacement is 12km from your original position. DISPLACEMENT DISTANCE DOS - Ringwords

Speed - is the distance traveled divided by the time needed to travel the distance Constant speed - speed is the same at any given moment in time Changing speed - speed at a particular instant in time SPEED = DISTANCE(6 M) = 2 m/s TIME(3 S) Velocity – is the displacement divided by the time. (Speed of a object and the direction of motion) VELOCITY = DISPLACEMENT (1 km east) =.5 km/h east TIME (0.5 h) TAKE NOTES!

4
Acceleration - is the change in velocity divided by the amount of time required for the change to occur (speeding up or slowing down) ACCELERATION = FINAL SPEED-INITIAL SPEED (8m/s - 2m/s)= 6m/s =.5m/s 2 TIME (12s) 12s Turning or changing direction is also acceleration.

6
Speed – distance something moves in a certain time Velocity – speed in a certain direction Acceleration – a change in speed a. Positive b. Negative You can change motion by changing the a. Speed (distance) b. Velocity (direction)
