Simple Machines:
-Wedge
-Inclined Plane
-Screw
-Pulley
Types of Energy
- Sound energy
- Kinetic/Mechanical energy
- Electric energy
- Gravitational energy
- Thermal energy
- Elastic energy
step 1. My phone vibrates causing a ball to roll off the phone onto a wedge. (sound and electric transfers to kinetic energy.)
step 2. The ball jumps across the gap onto a inclined plane. (Kinetic energy.)
step 3. the ball rolls onto a pulley system and due to the new weight the pulley falls. (kinetic transfers to gravitational energy.)
step 4. The pulley falls onto a inclined plane causing the ball to roll down into a corkscrew. (Gravitational transfers to kinetic.)
step 5. The ball’s speed increases while going down the corkscrew, after exiting the corkscrew the ball hits paper causing a tea bag to fall. (Kinetic transfers to elastic energy, which then transfers to gravitational.)
step 6. The tea bag falls into a hot cup of water (elastic energy transfers to gravitational energy, which then transfers to thermal energy.)
