Gravity Quiz

__________ is the amount of matter an object has.

• Mass

• weight

• kilograms

• gravity

A force of attraction that pulls objects that have mass together.

• Mass

• Newtons

• Gravity

• Kilograms

What two factors influence gravitational force?

• Weight and distance

• Apples and Newton

• Mass and Weight

• Mass and Distance

The ______ mass you have, the more gravity you have.

• weight

• more

• gravity

• less

always attractive, noncontact forces between objects that have mass

• gravitational force

• orbit

• attractive

• force field

Force Field

• a model that describes what the force on an object would be if the object were placed in any location in space

• the path that an object in space follows around another object due to gravitational forces between the objects

• when referring to forces, pulling together

• the amount of gravitational force on an object; weight is measured in newtons

What unit is used to measure weight?

• pounds

• ounces

• grams

• newtons

What is true about gravitational fields?

• 1. The moon has no gravitational field.

• 
  The strength of a gravitational field decreases with distance.

• 1. Earth's gravitational field is weak near Earth's surface.

• 1. The strength of a gravitational field increases with distance.

Which of the following describes gravitational force?

• contact, repulsive

• contact, attractive

• noncontact, attractive

• noncontact, repulsive

Why do astronauts in a space station in orbit not hit the floor of the space station?

• The astronauts are protected from the pull of gravitational forces by the space station.

• The astronauts’ masses are too small to be affected by the pull of Earth’s gravity.

• The astronauts and the space station fall to Earth at the same rate.

• There is no gravitational force working on the astronauts.
