Gravity and Motion

Review of gravity and motion

The force that attracts all objects toward each other. Gravity
The force of gravity on an object. Weight
This states that every object in the universe attracts every other object. Law of universal gravitation
The strength of the force of gravity depends on two factors:___________________ and ___________________. Mass and Distance
The amount of matter in an object. Mass
If mass increases, gravity __________________. Increases
The tendency of an object to resist a change in motion. Inertia
This states that an object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force. Newton's First Law of Motion
If distance increases, gravity _____________________. Decreases
These two factors combine to keep the Earth in orbit around the Sun and the Moon in orbit around the Earth. Gravity and Inertia
If mass decreases, gravity _________________. Decreases
What would happen to your weight if you traveled to a planet that has a greater mass than Earth? Your weight would increase
If distance decreases, gravity ______________________. Increases
What would happen to your mass if you traveled to a planet with a smaller mass than Earth? Your mass would stay the same
If the mass of Earth suddenly doubled, what would happen to the gravitational force of Earth? The gravitational force would also double.
What would happen if the Sun suddenly disappeared from our solar system? The planets would fly off through space in straight lines.
What would happen if the Earth lost inertia? It would fall into the Sun.
