What is normal force up and gravity down.
The object used to represent forces on a free body diagram.
What is an arrow?
A push or pull on an object.
What is a force?
The force that always opposes motion.
What is friction.
The support force that counteracts gravity.
What is normal force?
Draw a free body diagram of a force that accelerates a cart on a rough surface.

Gravity down Normal Force up and force of Friction.
This attractive force pulls objects together due to their masses.
Gravity
Pulling force applied to an object that can make an object stretch.
