3 complete cycles
4 complete cycles
5 complete cycles
6 complete cycles

Point A
Point B
Point C
None of the above
An adult drops a barbell on a smooth gym floor. It begins rolling toward a glass mirror. Which of the following would be necessary to change the direction of the rolling barbell?
A magnetic force
A balanced force
A gravitational force
An unbalanced force
Which of the following events is most likely caused by the force of gravity?
A breeze moves a piece of trash across a parking lot.
A puddle of water evaporates on a warm day.
A coin is flipped into the air, then falls toward the ground.
A campfire warms the skin of a person sitting nearby.
The picture shows some forces acting on a hawk as it takes off from the ground. Which arrow represents the force of gravity?

A snowboarder stands along the upper edge of a half-pipe, and quickly glides down to the center. As she approaches the opposite edge, her motion slows, and she begins to move toward the center again. Why does the snowboarder never reach the top of the opposite edge?
The force of gravity pulls her back toward Earth’s center.
The mass of the snowboarder pulls her away from Earth’s center.
The force of gravity pulls her away from Earth’s center.
The force of the snowboarder pulls her toward Earth’s center.
Two identical objects are dropped at the same time, one in the Northern Hemisphere, and the other in the Southern Hemisphere. Which of the following accurately describes the effect of gravity on the two objects?
Both objects are drawn toward Earth’s center by Earth’s gravity.
Both objects are drawn away from the Earth’s center by Earth’s gravity.
The object in the Northern hemisphere is drawn toward Earth’s center by Earth’s gravity, while the object in the Southern Hemisphere is drawn away.
The object in the Southern hemisphere is drawn toward Earth’s center by Earth’s gravity, while the object in the Northern Hemisphere is drawn away.
Which of the following statements most accurately describes why the moon orbits Earth?
The moon is repelled by the mass of Earth’s neighboring planets, Venus and Mars.
The moon orbits Earth because the force of gravity causes the mass of the moon to be attracted to the mass of Earth.
The air currents in space cause winds to circulate around the moon and Earth, pushing the moon toward Earth.
Because there is no water on the moon, its dry surface is pulled in by the moisture in Earth’s atmosphere.
Which of the following statements most accurately describes why an object weighs more on Earth than on the moon?
The moon has more mass than the Earth, so its magnetic field is stronger.
The moon has more mass than the Earth, so it has a stronger gravitational pull.
The Earth has more mass than the moon, so its magnetic force is weaker.
The Earth has more mass than the moon, so it has a stronger gravitational pull.
A child is shown jumping on a trampoline. No matter how high the child jumps, they will always land because:
inertia pulls the child down.
the force of gravity pulls the child down.
a magnetic force pulls the child down.
air resistance pushes the child down.
The diagram shows two objects in the solar system. Which of the two objects has the greater gravitational force?
Object 1
Object 2
The objects have equal gravitational force.
Neither object has a gravitational force.
The diagram shows two objects in the solar system. Which of the following changes would lead to an increase in the force of gravity between the two objects?
The mass of the larger object decreases.
The mass of the larger object increases.
The distance between the two objects increases.
None of the above.
Which of the following statements best explains why objects do not quickly fall to the floor when released by an astronaut on a spacecraft?
A. Objects with less mass have a stronger force of gravity in space than on Earth.
B. Objects in space fall slowly, because the force of gravity from Earth decreases as the distance from Earth increases.
C. Earth is the source of all gravity in the solar system.
D. Objects have a higher mass on a spacecraft than on Earth.
A pair of students drop a bowling ball and a feather from the same height at the same time. Which of the following statements best explains why the bowling ball hits the ground first?
A. The bowling ball has less mass than the feather, so the force of gravity on the bowling ball is lesser.
B. The bowling ball has less mass than the feather, so the force of gravity on the bowling ball is greater.
C. The bowling ball has more mass than the feather, so the force of gravity on the bowling ball is greater.
D. The bowling ball has more mass than the feather, so the force of gravity on the bowling ball is lesser.
A soccer player kicks a ball toward the opposing goal. A family is watching the game on TV, and they discuss the force the player applied to the ball. Son: “The forces acting on the ball were balanced, because the ball did not leave the ground.” Father: “No, the forces were unbalanced. That is why the ball changed direction.”
Neither is correct.
The son is correct.
The father is correct.
Both are correct.
A student pushed four wooden blocks across a smooth floor and recorded the data shown in the table. Which question can best be answered using this data?
Do objects travel slower over time?
Does applying more force make an object move faster?
How quickly can a 100 gram object be moved?
Which object takes the least time to slide across the floor?
Mara is conducting an investigation comparing the amount of dry food consumed by her 6-year-old cat and 3-month-old kitten. She creates a chart and records the amount of food consumed by each cat over a 2-day period. How can Mara improve the precision of the data collected in her investigation?
Collect data over a longer period of time.
Wait until the following morning to record data from the previous day.
Change the type of dry food offered to the two cats each day.
Record data on a different type of chart each day.
A student pushed four wooden blocks across a smooth floor and recorded the data shown in the table. The student wonders what impact the smooth floor had on the data collected in the investigation. How can the student best determine the impact of the smooth floor?
Repeat the investigation with different amounts of force applied.
Repeat the investigation for longer amounts of time.
Repeat the investigation on a floor with a rough texture.
Repeat the investigation on another floor with a smooth texture.
Two classes compete in a tug-of-war game on Field Day. Which of the following statements best explains why Class A won, while Class B did not?
The forces between the two classes were balanced.
No forces existed between the two classes.
The forces between the two classes were unbalanced.
The forces between the two classes were neither balanced nor unbalanced.
Which of the following statements best explains how an electronic satellite stays in orbit around Earth?
The mass of the satellite pulls the satellite toward Earth’s center.
The shape of the satellite pulls the satellite toward Earth’s center.
The magnetic force of Earth pulls the satellite toward Earth’s center.
The gravitational force of Earth pulls the satellite toward Earth’s center.
