440 - How do mechanical systems convert energy from one form to another?

Imagine a bike. It's a mechanical system. Here's how it converts energy:

1. Your body creates energy when you pedal (chemical energy from food you eat).
2. The pedals turn the gears (kinetic energy).
3. The gears turn the wheels (still kinetic energy).
4. The wheels move the bike (kinetic energy to movement).
5. The brakes turn movement into heat energy when you stop (friction).

So, mechanical systems like a bike convert energy from one form to another, like:

• Chemical energy (from food) to Kinetic energy (from pedaling)
• Kinetic energy to Movement (from wheel turning)
• Movement to Heat energy (from braking)

It's all about changing energy from one form to another to make things work.
