Pushes DOWN on everything.​

​

​Some text here about the topic of discussion.

​Gravity (F_g)

​

Normal force is OPPOSITE gravity. It pushes upward from the surface to the object and prevents things from falling through whatever they are resting on.​

​

​Normal Force (F_n)

​

​Forces that are applied by people or other things. The arrow will face the direction of the force being applied.

​

Examples: pushing a box, driving a car, pulling a door.

​

​​Applied force (F_a)

​

​Two surfaces rubbing together create friction. This force is OPPOSITE applied forces.

The arrow will face opposite of the applied force.​

​​Friction (F_f)

​

​

​A diagram that shows the forces on an object is called a free body diagram.

Draw the picture below on a paper to use as a reference for the next couple of questions! Or scroll back to this slide if you can.​
