A student is performing an investigation on unbalanced forces. The student applies a force to an object
and observes the result. Which result would provide the best evidence of the existence of an unbalanced force?
The object has a change in mass.
The object has a change in size.
The object has a change in shape.
The object has a change in motion.
Which situation is an example of balanced forces?
A boy pushes a box uphill.
A girl speeds up on a bicycle.
A cookie jar sits on the counter.
A toy car slows down on the carpet.
Which object experiences the highest gravitational force?
object W because it has the largest size
object X because it has the largest mass
object Y because it has the smallest mass
object Z because it has the smallest size
Which is an example of unbalanced forces?
A book sits on a shelf.
A girl kicks a soccer ball.
A cat sleeps on the couch.

Read the passage about David and Delia and look at the picture of a seesaw.
David and his friend Delia arrive at the playground. David and his friend are so much alike. They are the same age, the same height, and they even weigh the same. They can't wait to play on the new seesaw at the playground. David hops onto one side and Delia hops onto the other.
What most likely happen to David and Delia on the seesaw?
David and Delia will move up and down because their forces are unbalanced.
David and Delia will move up and down because their forces are balanced.
David and Delia will not move because their forces are unbalanced.
David and Delia will not move because their forces are balanced.

Point A
Point B
Point C
Point D
Read the passage about Marquis.
Marquis has been tasked with the job of helping his sister move into her college dorm room. He has to help unload the moving van, take boxes up the elevator to the third floor, put them on a moving cart to roll them to the room, prop the door open, and then unload the boxes onto the floor.
What are all the simple machines that Marquis must use in order to complete his job?
wedge, lever, inclined plane, and gear
pulley, screw, inclined plane, and wedge
wheel and axle, inclined plane, wedge, and lever
inclined plane, pulley, wheel and axle, and wedge

Which of the following experiments would help Rita find out which block would work best at stopping the
ball's motion?
Roll the ball down the ramp with the same force and put one of the four blocks at the end of the ramp
during each ball roll. Repeat this multiple times for each block.
Roll the ball down the ramp with different forces each time a new block is put at the end of the ramp.
Repeat this once for each block.
Roll the ball down the ramp with the same force, and put all four blocks at the end of the ramp at the same
time. Repeat this multiple times, using all four blocks at once.
Roll the ball down the ramp with a light force for two blocks, and a strong force for the other two. Repeat
this once for each block.
Andrew does the same experiment with four different cars. He takes the mass of each car and the records
the time it takes each to travel 60 centimeters to the edge of the table. He creates a data table organizing his findings. Which table most likely represents his findings?
Both dogs are pulling the rope but they do not move. Which statement best describes the forces while the
dogs are pulling but not moving?
Max and Otto are pulling with balanced forces in opposite directions.
Max and Otto are pulling with unbalanced forces in opposite directions.
Max and Otto are pulling with balanced forces in the same direction.
Max and Otto are pulling with unbalanced forces in the same direction.
Andrew glues a 5 kg weight to the top of one car. Which statement describes the most likely effect it will
have on the car?
The car has more mass and more force pulling on it, so it will take less time to reach the edge of the table.
The car has less mass and more force pulling on it, so it will take more time to reach the edge of the table.
The car has less mass but the same amount of force pulling on it, so it will take less time to reach the
edge of the table.
The car has more mass but the same amount of force pulling on it, so it will take more time to reach the
edge of the table.
