ExperimentHow Batteries Work (Part 2)
What You'll Learn
A force is a push or pull that can change an object's motion, shape, or direction. Forces are measured in Newtons and can act through contact or at a distance.
Key Words
- motion
- balanced
- gravity
Materials Needed
- ramps
- string
- weights
- tape
Safety First
- Do not look directly at the sun or bright lights.
- Clean up spills immediately to prevent slipping.
- Use materials only as directed in the experiment.
