12 Motion Energy Examples in Everyday Life

Motion Energy Examples in Everyday Life

All objects have potential energy stored within them. The amount of potential energy in an object depends on its position in relation to other objects. A trolley at rest has some potential energy caused by its weight. When you push the trolley, you exert force on it, making it move. The moving trolley now has …

How is the Doppler Effect Used in Astronomy?

How is the Doppler Effect Used in Astronomy

When a truck sounding a horn approaches you, the horn’s pitch increases gradually and is highest as the truck passes near you. As the truck recedes, the pitch gradually decreases. The variation in sound as the source approaches the receiver and as it moves away is caused by the Doppler Effect.  The Doppler Effect, also …

8 Real-Life Examples of Compressional Waves

Real-Life Examples of Compressional Waves

Compression and rarefaction are just like siblings. That’s because they stay right next to each other as neighbors in longitudinal waves.  When we speak of compressional waves, we are usually referring to mechanical longitudinal waves. Since they are mechanical waves, they need a medium through which they can be transmitted. This is unlike electromagnetic waves …
