Gravity

Gravitational interactions are attractive and depend on

• the masses of the interacting objects

• the size of an object

• the amount of gas in the atmosphere

• how many objects are in the system

As distance increases between objects

• gravitational force increases

• gravitational force decreases

• gravitational force stays the same

• the size of the object also increases

Mass is the measurement of how much _____ is in an object

• gravity

• weight

• force

• matter

Weight is the measurement of the force of ________ on an object.

• gravity

• force

• weight

• matter

The Law of Universal Gravitation is credited by whom?

• Einstein

• Smith

• Darwin

• Newton

What two factors keep a planet in orbit?

• mass and size

• gravity and intertia

The force of gravity between two objects is affected by which two factors?

• mass and distance

• weight and mass

• distance and weight

• matter and density

Jupiter has 317 times more mass than Earth. What can you infer is true about Jupiter?

• Jupiter's gravitational force is weaker than Earth's gravitational force.

• Earth and Jupiter probably have similar gravitational pull.

• Jupiter does not have gravity because it is a gas giant.

• Jupiter's gravitational force is stronger than Earth's gravitational force.

What unit is used to measure force?
