The Energy of Motion: Understanding Kinetic Energy
- What It Is – Kinetic energy is the energy an object has because it’s moving.
- Speed Matters – The faster something moves, the more kinetic energy it carries.
- Mass Counts Too – Heavier objects pack more kinetic energy at the same speed.
- Formula for Motion – Kinetic energy is calculated as ½ × mass × velocity².
- Everyday Example – A rolling bowling ball has more kinetic energy than a rolling tennis ball.
- From Cars to Bikes – Vehicles in motion store huge amounts of kinetic energy, which brakes must safely absorb.
- Collisions Show It – When objects crash, their kinetic energy transfers, often as sound, heat, or damage.
- Sports in Action – A soccer ball kicked harder flies farther thanks to greater kinetic energy.
- Changing Forms – Kinetic energy often transforms into other energies, like heat, sound, or potential energy.
- Life in Motion – From flowing rivers to running humans, kinetic energy powers the world around us.
