What is a force?

A force is how you raise X-wings out of swamps.

Somethings that Jedi's use when they really focus.

A force is a push or a pull.

Nobody really knows.

What is friction?

A the ability to do work, either to make an object move or to change matter

B force between surfaces that resists the motion of one surface past another surface; friction creates heat

C an object’s direction and speed

D Scientist who came up with 3 laws of motion; also the unit used to measure the amount of force applied
