Vocab
A place or object used for comparison to determine if an object is in motion
Reference Point
A variable that tells you both speed and direction.
Velocity
Work: 50j
Force:

On a distance over time graph, what are your x and y axis labels?
x: time
y: distance
Formula for work
Work = Force x Distance
An objects location
Position
Formula for speed
Speed= Distance / Time
Distance:
Speed: 150m/s
Time: 30s
On a speed over time graph, what are your x and y axis labels?
x: time
y: speed
A result of a force moving an object a certain distance.
Work
A change in position over time
Motion
a measure of the change in velocity during a period of time

On a speed over time graph, if a line has a negative slope, what does it represent?
(example on board)
Deceleration
SI unit for speed
m/s
The rate at which an object is moving at a given moment in time
Instantaneous Speed
The overall rate of speed at which an object moves; calculated by dividing the total distance an object travels by the total time.
