I was wondering if you could explain to me about pressure. I am doing an experiment about wave energy. My experiment involves dropping a rock into water and measuring its wave energy, so I was wondering how the pressure affects and how much wave energy is produced. I am writing my abstract, and am not sure how to incorporate pressure into it. I am also asking, could you please explain to me in simple terms, what wave energy really is and how you find it? I am also doing an experiment on wave energy but the problem is that I don't quite understand it. Could you please explain to me in simple terms, what wave energy really is and how do you find it?

Answer 1:

The pressure is a force. When we want to know the force acting per unit area on any surface, we think of pressure. If you push your head with one of your hands, this hand is applying a force on your head; the area of your head that feels that force is perpendicular to it. Now, if you want to know the force that your head feels per unit area, then you speak about pressure.A wave is a kind of energy that propagates through a medium. When you drop a rock into the water there is a pressure on the water and a wave appears as a result. This wave starts propagating through the water, carrying on the energy that you applied by dropping the rock.As you probably see, pressure and waves are completely related. For instance sound is a mechanical wave. This mechanical wave results from the motion of tiny particles of the medium through which the sound wave is moving. In the case of your experiment, when you drop the rock, you produce a mechanical wave that travels through the water (the medium), using the energy that you applied by dropping the rock into that medium (the water).I hope this helps!
