Pulse (physics)

Pulse in physics is like when you move something really fast and then stop it suddenly. Imagine you are playing catch with a ball. If you gently throw the ball to your friend and they catch it, that's like a soft and slow wave. But if you throw the ball really hard and your friend has to quickly stop it with their hands, that's like a pulse. It's a sharp, quick movement that stops suddenly.

In terms of things like sound or light waves, a pulse is a quick burst of energy that travels through the air or other medium. It's like a single beat or thump instead of a continuous hum or buzz. Scientists can use special machines to create pulses of different types to study how they behave and to learn more about the world around us.
