A
Velocity
3
Q
- If you ride your bicycle down a straight road for 500 m then turn around and ride back to your starting point, your distance is
A
Greater than your displacement
4
Q
- An object in motion must be undergoing a change of
A
Position
5
Q
9.What is his average speed?
A
0.25 km/min
6
Q
- What is the distance covered by the object between the 2nd and 6th second?
A
8 m
7
Q
- Find the acceleration of the bicyclist in the graph to the right from 5 s to 6 s.
A
15 m/s^2
8
Q
- According to the graph, as time increases, the speed of the car
A
Stays the same
9
Q
- Which statement can be made about the pony’s motion?
A
The pony is accelerating
10
Q
- The velocity must include both a
A
Speed and a direction
11
Q
- Can the velocity of a car change when it’s speed is constant?
A
Yes because velocity is speed and direction, you could be making at a constant speed but changing direction, this velocity changes.
12
Q
- Describe the motion of a biker at A, B and C as shown by the distance vs. time Graph.
A
A= constant speed B= not moving C= constant speed- slower then part A
13

A
D= 5.20 m T= 10.4 s
14
Q
- If he is riding it constantly at this rate, how far did he ride?
A
S=60 km/hr
T= 1.5hrs
15
Q
- What is your acceleration?
A
a= -6 km/hr^2
