- 2. Multiple Choice
A car travels at a speed of 7.0 m/s. What is this speed in km/h?
20km/h
70km/h
25.2km/h
4km/h
- 3. Multiple Choice
Identify Newton's First Law of Motion
F = m x a
An object will accelerate in the direction of an unbalanced force acting upon it. The size of this acceleration depends upon the mass of the object and the size of the force acting.
For every action force there is an equal and opposite reaction force
An object will remain in a state of constant motion unless an unbalanced force acts on it
- 4. Multiple Choice
Identify the Net Force acting on the object
240N
160N
140N to the right
50N to the left
- 5. Multiple Choice
Identify the velocity of the object at 2 seconds
8m/s
0m/s
4m/s
7m/s
- 6. Multiple Choice
Identify the displacement of the object after 10seconds
64m
8m
72m
16m
- 7. Multiple Choice
What distance would a ladybird cover, crawling at a speed of 1.20 m/s, in an hour (3600s)?
1.2m
3,000m
3400m
4,320m
- 8. Multiple Choice
Which best explains why we are able to accelerate forward when starting to run?
The foot not touching the ground propels the entire body as it swings forward.
The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.
The runner’s upper body quickly leans forward, causing the entire body to begin accelerating forward.
As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.
- 9. Multiple Choice
Describe the motion of the object between 6 and 8 seconds.
The object is decelerating
The object is moving at a constant velocity
The object is speeding up
The object is stationary
