INTRODUCTION TO FORCES

Basic forces of GRAVITY and APPLIED FORCE

BALANCED FORCES on a person

BALANCED FORCES involving FRICTION and NORMAL FORCE

Example of all 4 forces on an object

Most of these labels on this car are NOT the terms we just discussed. How can you compare these terms with the previous terms (normal force, applied force, gravity)?

Forces are measured in NEWTONS. Study the three situations below, be sure to notice the RESULTANT (NET) FORCES:

Simple diagram showing all forces in Newtons. What is the resultant (net) force?

This diagram represents a toy car in motion. Draw it in your ISN and add a VECTOR labeled in Newtons to represent the applied force of the car to the right.

15N Magnitude of motion is 10 N to the right
