Objective
I can describe the effect of balanced and unbalanced forces on an object's motion.
Part 1 of 3
Key concepts
3 concepts
- 1
Forces are pushes or pulls that can influence an object's motion, and their combined effect is known as the net force.
- 2
Balanced forces occur when the net force on an object is zero, meaning the object will either remain at rest or continue moving at a constant speed in a straight line.
- 3
When unbalanced forces act on an object, the net force is greater than zero, causing its motion to change by accelerating, decelerating, or changing direction.

7 questions
What is the net force, and why is understanding it important for predicting an object's motion?
A book is resting motionless on a table. Are the forces acting on the book balanced or unbalanced? Explain how you know.
