gravity
friction
mass (weight)
Luis and Max left their school at 2:45 p.m. to go to the library. Luis rides his bike at a speed of 10 miles per hour. Max rides his bike at a speed of 12 miles per hour. Which of the following is most likely to happen?
A. Luis and Max will arrive at the library at the same time.
Luis will arrive at the library before Max.
Max will arrive at the library before Luis.
Luis and Max will ride their bikes in two different directions.
Which of the following statements best explains why it can be dangerous to drive a car on an icy road in the winter?
Ice increases the force of gravity acting on a car.
Ice increases the mass (weight) of a car.
Ice reduces the friction between the car’s tires and the road.
Ice reduces the speed of the car.
A biologist observes a bat in motion. The bat flies a distance of 2 miles. If the biologist wants to determine the bat’s speed, what other information
does she need?
She needs to know the amount of time the bat flies.
She needs to know the direction the bat flies.
She needs to know the bat’s starting position.
She needs to know the bat’s mass while it is flying.
The picture shows water flowing down the side of a mountain. Which of the following causes water to flow down the sides of mountains and hills?
friction
speed
direction
gravity
Reece rolls a ball down a smooth, wooden ramp and observes the motion of the ball. Then he places sandpaper on the ramp. Next, he rolls the same ball down the ramp covered with sandpaper and observes the motion of the ball. What is Reece most likely investigating?
He is investigating if a change in gravity affects the motion of the ball.
He is investigating if a change in friction affects the motion of the ball.
He is investigating if a change in mass affects the motion of the ball.
He is investigating if a change in direction affects the motion of the
ball.

Box A has more mass (weight) than Box B.
Box A and Box B have no mass (weight).
Jack formed a smooth ball out of clay. He pushes the ball and observes its motion across the table. What can Jack do if he wants the ball to move faster when he repeats the activity?
Jack can push the ball with less force.
Jack can change the ball’s starting position.
Jack can add more clay to make the ball heavier.
Jack can push the ball with more force.
Jake’s dad drove from Raleigh to Greensboro in 1 hour and 30 minutes. What additional information does Jake need to find his dad’s driving speed?
Jake needs to know the force of gravity acting on his dad’s car.
Jake needs to know the mass (weight) of his dad’s car.
Jake needs to know about the friction between the tires and the road.
Jake needs to know the distance from Raleigh to Greensboro.
Which of the following best describes friction?
A force that pulls objects toward the ground.
A force that is created when two objects move across each other.
A force that pulls two objects apart.
A force that makes an object move faster.

The softball will move faster and go farther when Makayla hits it.
The softball will move slower and go farther when Kim hits it.
The softball will move faster and not go as far when Makayla hits it.
