Spring Scale

What is it?
A spring scale measures force or weight using a spring that stretches when pulled. It shows force in Newtons or mass in grams.

Where do I use it?

• Sightseeing Cable Car – Measure the pulling force needed to move loads.
• Rope Climbing Robot – Record how much force is needed for climbing.

Why is it important?
Force is one of the core ideas in physics. Measuring it helps us understand balance, motion, and how machines reduce effort.
