Q
- Ben is exercising his pony on a large, oval track. The pony is trotting at a constant speed of 10 m/s around the track. Which statement can be made about the pony’s motion?
A
The pony is accelerating
Unit 6 Concept 1,2 pg 4
12
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 moving at a constant speed but Changing direction, thus velocity changes.

Q
- Explain the difference, in relation to speed, between positive and negative acceleration?
A
+ acceleration is speeding up and - acceleration is slowing down.
