What happens to the strength of gravity if the distance between two objects increases?
The strength of gravity decreases
What is inertia?
The tendency of an object to resist a change in motion
How do objects stay in orbit?
Objects have a tendency to keep moving forward in a constant direction and speed due to inertia, but gravity causes the object's path to curve towards a mass.
What is Newton's law of universal gravitation?
Every object in the universe attracts every other object
What is Newton's first law of motion?
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
What is a force?
A push or pull
What does the strength of the force of gravity depend on?
The mass of two objects and the distance between them
What happens to the strength of gravity if the mass of an object increases?
The strength of gravity increases
What is gravity?
The force that attracts all objects toward each other
