A fourth grade student dropped an egg and feather at the same time. Which statement best describes the relationship between gravitational force and the objects?

• The gravitational forces pulled the egg down faster because the feather is affected by air resistance.

• The gravitational forces pulled the feather down faster because it has less mass than the egg.

• The gravitational forces pulled the feather and the egg down at the same speed because they are equal masses.

• The gravitational force had zero effect on either object because they both fell.

Which argument best supports the image below?

• The basketball and tennis ball will hit the ground at the same time because of gravitational forces

• The basketball will hit the ground after the tennis ball because it is larger so it takes more time to fall

• The tennis ball will hit the ground after the basketball because the basketball has a higher mass

• The tennis ball will hit the ground before the basketball because it is smaller so it takes less time to fall

Which of the following statements best supports the claim that gravitational force affects the motion of an object?

• Gravitational force is a natural phenomenon that only affects objects in space.

• Gravitational force pulls objects toward the center of the Earth, causing them to fall when dropped.

• Gravitational force pushes objects away from each other, making them float in the air.

Which of the following best describes how a pulley system changes forces when used to lift up an item?

• When the man pulls down on the rope to raise the object, the force is being transferred through the machine instead of having to lift the object by himself.

• The pulley acts like a second pair of hands and lifts the box on its own.

• The pulley uses force from the crate to pull the man down.

• The pulley allows for energy to be transferred from the person to the crate.
