gravity

What keeps the planets in orbit around the sun?

• gravity

• friction

• density

• distance

A person would weigh more on Jupiter than on the Earth because . . .

• Jupiter has more mass, and therefore more gravity
• Jupiter has less mass, and therefore more gravity
• Jupiter has more mass, and therefore less gravity
• Jupiter has less mass and therefore less gravity

Which of the following will not change in different gravitational fields?

• weight
• force
• mass
• pounds

A brick and a pencil are dropped at the same time from the same height. Which one would hit the ground first?

• brick

• pencil

• both would hit at the same time

What two things determine the gravity of an object?

• mass & weight

• mass & distance

• density & mass

• volume & distance

When will the forces of gravity between two objects be the GREATEST?

• when the masses of both objects are small and the objects are far apart

• when the masses of both objects are large and the objects are close together

• when the masses of both objects are small and the objects are close together

• when the masses of both objects are large and the objects are far apart

When will the gravity between two objects be the LEAST?

• when the masses of both objects is small and the objects are close together

• when the masses of both objects is small and the objects are far apart

• when the masses of both objects is large and the objects are close together

• when the masses of both objects is large and the objects are far apart
