Forces and Motion Unit Review

An object moves in a straight line a distance of 5 meters in 10 seconds. What action could result in an increase in the speed of the object?

• Increasing the amount of time it takes the object to move 5 meters

• Making the object move 5 meters in 10 seconds but in the opposite direction

• Making the object move 5 meters in 10 seconds but in a perpendicular direction

• Decreasing the amount of time it takes the object to move 5 meters

The diagram below shows four different objects that all start at the same place and move along the same path. Which best describes the motion of these objects?

• Object 1 has traveled farther than the other objects.

• Both Objects 2 and 3 are a higher elevation than Object 1

• Both Objects 1 and 2 are at a lower elevation than Object 4

• Object 4 has traveled farther than the other objects

Mikayla stands on a beach and sees a sailboat in the ocean. How could Mikayla determine whether the sailboat is moving?

• By using a reference point to measure the change in the boat’s position over time

• By examining the height of the ocean waves

• By determining the weight of the boat

• By comparing the wind speed at the beach to the number of ocean waves

This graph shows the motion of a car during two trips. Which statement describes the speeds of the car during both trips?

• The car traveled at various speeds during Trip 1 and at a constant speed during Trip 2

• The car traveled at a constant speed during each trip

• The car traveled at a constant speed during Trip 1 and at various speeds during Trip 2

• The car traveled at various speeds during each trip

A stationary object experiences two forces, as shown in the diagram below. How will these forces affect the object?

• The object will accelerate because the forces are balanced

• The object will accelerate because the forces are unbalanced

• The object will remain stationary because the forces are balanced

• The object will remain stationary because the forces are unbalanced
