Gravitational Force Quiz

The gravitational force between two objects -

• is negligible, unless both objects are very massive

• can push or pull, depending on the mass of each object

• always pushes objects away from each other

• always pulls objects toward each other

Which of the following would support the claim that the gravitational force between objects depends on mass?

• An object's weight can change depending on where it is on Earth.

• The farther apart a planet is from the Sun, the smaller the gravitational force will be.

• Gravitational force is stronger on more massive planets.

• A rocket can escape Earth's gravity by traveling at high speed.

A box rests motionless on the ground. A student is pushing the box to the right with a force of 2 newtons. Another student is pushing the box to the left with a force of 5 newtons.

In which direction and with what type of speed will the box move?

• It will move left at a constant speed.

• It will move left at an increasing speed.

• It will move right at a constant speed.

• It will move right at an increasing speed.

If we assume that the only two forces acting on the toy rocket are lift and gravity, which of the following would result in the rocket moving upward?

• Lift = 4 newtons; gravity = 4 newtons

• Lift = 5 newtons; gravity = 4 newtons

• Lift = 3 newtons; gravity = 4 newtons

• Lift = 5 newtons; gravity = 5 newtons

The activity is repeated four times with the same results. Which pattern is seen in the activity?

• Small springs bounce higher than larger springs when the same amount of force is used.

• A spring will bounce the highest after a large force is applied.
  

• Large springs bounce higher than smaller springs when the same amount of force is used.

• A spring will bounce the highest after a small force is applied.

Groups of students pull on opposite sides of a rope. The center of the rope is marked with an X. Each student pulls with the same amount of force. In which direction will the center of the rope move, and why?

• The center of the rope will move to the left because there are more people pulling in that direction.

• The center of the rope will move to the right because there are more people pulling in that direction.

• The center of the rope will move to the left because there are fewer people pulling in that direction.

• The center of the rope will move to the right because there are fewer people pulling in that direction.
