Q
22.The graph represents the motion of a car.as time increases what happens to the speed of the car?
A
Stays the same
Note p1
11
Q
24, Which car has 0 acceleration?
A
The second car
Notes p2
12
Q
- Can the velocity of a car change when speed is constant?
A
Yes. Velocity is speed + direction. You could be moving at a constant speed but changing direction, velocity changes
