A car is travelling along a straight road as shown in the graph below. The car experiences no acceleration. Which of the following best describes the car’s velocity?
Velocity is decreasing
Velocity is increasing
Velocity is zero
Velocity is constant
The rate at which distance changes is known as
gravity
displacement
speed
acceleration
If an object is changing direction but maintaining a constant speed, it is
accelerating
falling
stopping
speeding
When you are driving and look at the speedometer to check how fast you are going, you are checking your
instantaneous speed
average speed
velocity
acceleration
If air resistance is negligible, (‘negligible’ means it’s so small it has NO effect), which of the following objects will fall faster on Earth?
all objects fall at the same rate
a baseball
a feather
a bowling ball

0 m/s
49 m/s
-9.8 m/s
-49 m/s
Calculate the final velocity of an object, dropped from rest after 5 seconds pass if air resistance is negligible.
5 m/s
-49 m/s
-9.8 m/s

velocity
acceleration
distance
speed
What is the acceleration due to gravity on earth if air resistance is negligible?
-9.8 m/s/s
32 m/s/s

A car is moving in the forward direction and applies the brakes. If forward is considered to be a positive direction, then which of the following is true?
velocity and acceleration are both positive
velocity and acceleration are both negative
velocity is negative and acceleration is positive
velocity is positive and acceleration is negative
Velocity and speed are
identical in every single way
different because velocity never has direction
the same as acceleration
different because velocity has direction
Acceleration is defined as the change in
distance divided by the time interval
velocity divided by the time interval
time it takes to move from one place to another
time it takes to move from one speed to another

2.9 s
4.1 s
A physics class wants to investigate a marble rolling across a horizontal table. Four groups collected the following data.
Which group could calculate the average velocity of the marble from the data they collected?
Group A, because displacement is needed to calculate velocity. The height provides the amount of gravitational force.
Group B, because displacement is needed to calculate velocity. The mass provides the amount of gravitational force
Group C, because displacement is needed to calculate velocity. The time is also required to determine the average velocity.
Group D, because time is needed to calculate velocity. The mass provides the amount of gravitational force.
The motion graph for a moving object is shown below.
Calculate the acceleration of the object during line segment B.
2 m/s/s
-2 m/s/s
1 m/s/s
-1 m/s/s
What would be the best formula to use to solve the following problem?
An astronaut drops a feather 1.2 m above the surface of the moon. If the acceleration of the feather (acceleration of gravity on the moon) is 1.62 m/s2 down, how long does it take the feather to hit the surface?
vf2 = vi2 + 2aΔx
v = Δx / t
Δx = vit + ½ at2
vf = vi + at
What represents the final velocity in the following question?
How long must the runway be in order for a light plane to reach 65m/s after accelerating at 3.0m/s2 for 15s?
0 m/s
15 s
65 m/s
3.0 m/s/s
Which would be the best formula to use to solve the following problem?
As Sally backs down her driveway, her car’s velocity changes from –1.0 m/s to –5.0 m/s in the 2.5 seconds it takes her to reach the end of the driveway. What is the car’s average acceleration down the driveway?
v = Δx / t
vf2 = vi2 + 2aΔx
vf = vi + at
Δx = vit + ½ at2
