This is the type of force that opposes gravity when the object is hanging on a string.
Tension.
The planet with most numbers of moons

This states that an object at rest remains at rest unless an outside force acts upon it.
First law of Newton
This type of diagram represents all of the forces acting on a single object.
Free Body diagram
True or false: The mass of an object changes if placed on different planets.
False, weingh may change but the mass remains the same.
True or false: The Moons pulls the Earth with a smaller force than the Earth pull on the Moon because it is smaller.
False
The reason a chair slows down after you push it accross the floor is due to this type of force.
Friction force
This is the type of force that opposes gravity when the object is at rest on a surface.
Normal force
These are the only two planets that are not named for Roman gods
What are Haumea and Makemake?
This law states that for every force that object A applies on B, object B pushes the same amount of force back, but in the opposite direct, of object A.
Newton's third law
Planets move in an Elliptical orbit around the Sun.
Who discovered this?
Johannes Kepler
Hottest planet in our solar system.
Venus
Momentum is _____
Product of mass and velocity
P = mv
