MOTION
- COMPARED TO
- Reference point
(Relative motion)
- Used for comparison
- Determines if something is in motion
- Two kinds
- Moving
- Might trick you
- Such as other car moving
- Stationary
- Preferably
- Such as tree or pole
- MEASURED IN
- Internationl system of Units (SI)
- Used by scientists
all over the world
- Describes all quantities
- Sush as length, mass
time, current,
temperature, intensity and
amount of substance
- "System Internationale" in French
- DESCRIBED BY
- Acceleration
- Increase in speed
- Decrease in speed
- Change in directiom
- Final speed minus
initial speed over
time
- Time always squared
- Rate at which velocity changes
- Graphs to analyse acceleration
- Speed versus Time
- Distance versus time
- HAPPENS WHEN
- Change in Velocity
- Speed
- Distance
over time
- Distance versus time graph
- Slope
- Steepness tells you
if moving slower or
faster
- Straight line = constant speed
- Represents rate of
change d/t (speed)
- Calculate by dividing rise over run
- Two Kinds
- Instantaneous
- Measured by speed graph
- Average speed
- Total distance over total time
- Direction
- Very crucial in some casses
