Push or Pull
This keeps Earth and the moon in orbit
What is Gravity?
The strength of gravity depends this
What is Mass?
Earth does not fall into the Sun because of this
What is Inertia?
In the 1600's this English scientist discovered gravity
Who is Isaac Newton?
The measure of the force of gravity on an object is known as
What is Weight?
The tendency of an object to resist a change in motion
What is Inertia?
Gravity attracts all objects toward each other through push and pull also known as
What is Force?
The force of gravity decreases rapidly as this increases
What is Distance?
An object has greater inertia when has
What is More Mass?
This states that every object in the universe attracts every other object
What is Newton's law of universal gravitation?
An objects weight can change depending on its location but this will not change
What is Mass?
This says that an object at rest will stay at rest and an object i motion will stay in motion with a constant speed and direction unless acted on by a force
What is Newton's first law of motion?
The strength of the force of gravity between two objects depends on two factors
What is Distance and Mass?
Because the Moon has less of these you would weigh 1/6th of your weight on Earth
What is Mass and Gravity?
These combine to keep Earth in orbit around the sun and the moon in orbit around Earth
What are Gravity and Inertia?
