6.2 Unbalanced Forces, Net force and motion
Unbalanced Forces and Net Force: Discover How Forces Change Motion
You will learn how unbalanced forces create a net force that makes objects start, stop, speed up, slow down, and change direction.
What You'll Learn
You learn that unbalanced forces cause objects to change their motion.
You calculate net force by combining all forces on an object.
You discover friction and gravity are forces that affect object motion.
You explore how force strength and direction determine what moves.
What You'll Practice
1
You will calculate net force using tug of war and push examples.
2
You will identify balanced and unbalanced forces from given scenarios.
3
You will match key force terms like friction, gravity, and motion.
Why This Matters
Understanding unbalanced forces and net force helps you explain and predict how objects move in the world around you every single day.
