Motion is a change in
Position
Speed = ?
Distance/time
A line on a distance –time graph with a steep slope indicates a
An increase in speed
To describe velocity you need to know
Speed and direction
Acceleration involves a change in
velocity
On a speed-time graph a horizontal line shows the speed is
constant
If your speed changes from 10 km/hr to 6 km/hr, you have a ____ acceleration
negative
What is the difference between distance and displacement
Distance is total length traveled and displacement is length from starting to ending
If you ran a complete circle around a 400 m track, what was your displacement
0

Slowing down greatly
If you travel 500 miles in 10 hours, what was your average speed
50 mph
If you are heading east at 5 m/s and a friend of yours is traveling west at 5 m/s, do you have the same velocity and why
No – different directions
