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.)
