Essential Questions
- What are balanced and unbalanced forces?
- How do balanced and unbalanced forces affect the motion of an object?
- How can we design investigations to test the effects of forces on objects?
- What evidence can we gather during an investigation to support our understanding of motion?
- Why is it important for scientists to use investigations when learning about forces and motion?
