Which objects have a STRONG force of gravity?

Objects with GREATER mass, like elephants

Objects with LESS mass, like mice

Why a ball falls to the ground?

Earth's force of gravity is GREATER than the ball's, so the ball gets attracted to the ground.

Earth's force of gravity is LESS than the ball's, so the ball gets attracted to the ground.

Is weight AFFECTED by gravity?

YES, depending on the force of gravity is how much you weight.

Amanda weighs about 600 N on Earth, but would only weigh about 100 N on the Moon. Which BEST explains why Amanda would weigh less on the Moon than on Earth?

The mass of the Moon is less than that of Earth, therefore it has a weaker gravitational force.

The circumference of the Moon is smaller than Earth, therefore it has less gravity.

The lack of air pressure on the Moon weakens the gravitational force of the Moon.

What is the relationship between mass and gravitational pull?

Higher/greater mass creates higher/greater gravitational pull

Lower mass creates higher gravitational pull

Lower gravitational pull creates more mass

Why doesn't the moon crash into the Earth?

The moon has a lot of mass and is farther away.

The moon has more mass, so the Earth orbits around it.

The moon's gravitational force is weak.

Inertia keeps the moon stationary.

Which of these best describes why your weight (on Earth) would change on another planet?

Different planets have different gravitational pulls

Dehydration effects on different planets change weight.

In general, the smaller the planet, the greater weight

Weight does not change, no matter where you are.

What is the relationship between mass and gravitational pull?

Higer mass creates higher gravitational pull

Lower mass creates higher gravitational pull

Lower gravitational pull creates more mass

What is the relationship between masses of 2 objects and the gravitational force between them?

The force of gravity is stronger when the masses are greater. If you move farther away, the force gets weaker.

Sabrina and Gabriela are ice skating at a local rink. Sabrina braces herself against a wall and pushes Gabriella across the ice. After the push, Gabriela slides by herself across the ice. Which of the following BEST describes the force or forces acting on Gabriela as she moves across the ice after Sabrina is no longer touching her?

The force of friction between the ice and her skates acts on Gabriela the entire time she slides across the ice.

There are no forces affecting Gabriela's motion once Sabrina is no longer pushing her.

The force from the push continues to act on Gabriela for a while, but its strength gradually fades.

The force from the push continues to act on Gabriela the entire time she slides across the ice.

Rochelle dives into a swimming pool full of water from a one-meter-high diving board. Which of the following BEST describes the results of the acting forces as the diver enters the water?

The water speeds up as the diver slows down.

There is no change in the speed of the diver or the water.

The water and the diver both speed up.

The water and the diver both slow down.

When a heart beats, electrical impulses occur in the muscles of the heart. These electrical pulses cause the heart to contract and retract. What force is applied to the blood when the heart muscles contract and pull inward?

a pulling force, forcing the blood outward through the body

a pushing force, forcing the blood outward through the body

a strong frictional force that pulls the blood upward and out of the heart

a strong gravitational force that pushes the blood upward and out of the heart
