Unit 4: Physics CFB 8th Grade

Balanced Forces are:

• constant motion and stationary objects

• increased speed

• decreased speed

• change in direction

Unbalance forces are

• constant motion

• increased speed and decreased speed only

• stationary object

• increased speed, decreased speed, change in direction
