Jessica is comparing two balls. One ball has a mass of 1 kg, and the other has a mass of 2 kg. She pushes each with a force of 100 N. How do the accelerations of the two balls compare?
The 1 kg ball accelerates the same as the
2 kg ball
The 1 kg ball accelerates half as much as the 2 kg ball
The 1 kg ball accelerates twice as much as the 2 kg ball
The 1 kg ball accelerates four times as much as the 2 kg ball
A fisherman steps off a boat, which is in the water, onto a dock. What happens?
The boat and dock do not move
The boat moves toward the dock
The boat moves away from the dock
The dock moves away from the boat
Look at the diagram of forces acting on an object. The picture shows a push and a pull acting on a box of books sitting on the floor. What is the net force toward the right on the box?
0 N
50 N
100 N
2,500 N

3.2
27
An airplane is traveling at a speed of 200 m/s relative to the Earth. A person walks toward the front of the plane at a speed of 1 m/s. How fast is that person traveling in reference to the other people on the airplane?
0 m/s
1 m/s
200 m/s
201 m/s
Carts A and B each have the same force applied to them. Cart A has half the mass of Cart B. How does Newton’s first law of motion predict the resulting accelerations of the carts?
Cart A will have the greater acceleration
Cart B will have the greater acceleration
Carts A and B will have the same acceleration
The law cannot predict the accelerations without additional information
How are velocity and speed related to each other?
Speed and velocity are both only a change in position over time
Velocity and speed both include the direction and a change in position over time
Speed includes the direction and a change in position over time, but velocity is only a change in position over time
Velocity includes the direction and a change in position over time, but speed is only a change in position over time

A force of 210 N is applied to an object and the object accelerates at 14m/s2. Determine the mass of the object in kg (m = F / a).
1.5kg
3kg
14kg
20kg
Two ice skaters on ice push away from each other. What will be the effect of the forces of their pushing each other if their masses are different?
The opposing forces are the same. The skater with the greater mass will have the lesser acceleration since a = F/m
The skater with the greater mass will have the greater force and the greater acceleration since a = F/m
The opposing forces are the same. The skater with the greater mass will have the greater acceleration since a = F/m
