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

Speed - is the distance traveled divided by the time needed to travel the distance
Constant speed - speed is the same at any given momentin 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 eastTIME (0.5 h)

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/s2
TIME (12s) 12s
Turning or changing direction is also acceleration.
