Motion Test Flashcards
1
Q
- What is 3 m/s an example of?
A
velocity
2
Q
- If a car moves around a wide turn going 45 mi/hr the whole time what is the constant
A
speed
3
Q
- If you ride your bike down a straight road for 500m then turn around and ride back to your straight point. Your distance is — your displacement
A
greater than
4
Q
- An object in motion must be undergoing a change of what
A
position
5
Q
- A softball pitcher throws a ball at 42 meters per second. if the batter is 18 meters from the pitcher, how much time does it take for the ball to reach the batter?
A
0.43 s
6

A
0.25 km/min
7

A
8 m
8
Q
- the unformed motion of a cart is shown in the distance versus time graph to the right. what is the speed of the cart.
A
2 m/s
9
Q
- the horses on a carousel or merry go round are accelerating because of what.
A
he direction of the horsed motion is constantly changing
10
Q
- At what point is the rate of change in velocity the greatest.
A
A.
11
Q
- Graph to the right which that’s according to the graph next time increases the speed of the car does what.
A
stays the same
12
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 motions
A
the pony is accelerating
13
Q
- The velocity of a object must include what
A
speed and direction
14
Q
- Can the velocity of a car change when it’s speed is constant? why or why not
A
yes because velocity is speed and direction. you could be moving at a constant speed but changing direction, then velocity changes
15
Q
- describe the motion of a biker at a b and c shown by the distance vs. times graph
A
a= constant speed b= not moving c= constant speed
