### Balanced and Unbalanced Forces

Dayna Lee Martínez

STARS - USF

Maniscalco Elementary

What is a force?
• A force is a push or pull that causes an object to move, stop, or change direction
• In physics a force is anything that makes an object accelerate
Force
• Forces come in pairs
• Forces have a magnitude and a direction

Magnitude: 5N

Direction: north (up)

5N, north (up)

Balanced and Unbalanced Forces
• Forces occur in pairs and they can be either balanced or unbalanced
Balanced Forces
• Balanced forces do not cause change in motion
• They are equal in size and opposite in direction
Unbalanced Forces
• An unbalanced force always causes a change in motion
• When unbalanced forces act in opposite directions you can find the net force
• Net force
• Magnitude
• The difference between the two forces
• Direction
• Direction of the largest force
Unbalanced Forces

3 N, right – 6 N, left = 3N, left

Unbalanced Forces

4 N, left – 10 N, right =

6N, right

Unbalanced Forces

5 N, right + 10 N, right =

15N, right
