TCI Gravity

The closer together the gravitational field lines.....

• the weaker the gravitational field strength

• the stronger the gravitational field strength

• the more repulsive the gravitational field strength

If a feather and a hammer are dropped at the same time on the moon, where there is no atmosphere, which one will hit the ground first?

• Neither, there is no gravity on the moon.

• hammer because it has more mass

• feather because it has less mass

• both will hit at the same time

When do gravitational forces exist between two objects?

• They only exist between microscopic objects.

• They are always present between any two objects.

• Gravitational forces only act on objects falling on Earth.

• They only exist for objects in space.

When you drop a hammer and a feather, why does the feather fall slower?

• air resistance causes the feather to slow down

• gravity pulls harder on the hammer than the feather

• gravity pulls harder on the feather than the hammer

• air resistance causes the hammer to fall slower

Which of these choices explains why this model of the solar system cannot be correct?

• Earth does not have enough gravitational pull to be located in the center of the Solar System.

• Venus is larger than the Moon so it would be located closer to the center.

• Saturn has as much mass as Earth so it would be located in the center.

• Mars and Mercury have an equal amount of gravitational pull so should be on the same orbital pathway.

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity

• Moon has less mass, and therefore more gravity

• Moon has more mass, and therefore less gravity

• Moon has less mass and therefore less gravity

If Earth's mass was cut in half, what would happen to your mass?

• increase because gravitational force increases

• decrease because gravitational force decreases

• decrease because gravitational force increases

• nothing, mass is not affected by gravitational force
