What happened to the energy when the diver hits the water?
When you then dive into the water, your potential energy is converted to kinetic energy as you fall, and when you hit the surface, some of that energy is transferred to the water, causing it to splash into the air. … This is known as the law of conservation of energy: Energy cannot be created or destroyed.
How does a divers kinetic energy change as the diver falls?
The gravitational potential energy of an object is converted to the kinetic energy of motion as the object falls. … The air friction slows the bouncing ball as the kinetic energy turns into thermal energy. To begin a dive, a diver jumps into the air and then lands on the diving board, causing it to bend.
Where do the divers have the most potential energy?
When you dive off diving board , you first press it downwards, causing it to store potential energy in it. When it has maximum amount of potential energy stored in it, the diving board converts potential energy into kinetic energy and pushes it up in the air.
What is the best example of a device that converts electrical energy ⇒ thermal energy?
Examples of Electrical Energy to Thermal Energy Conversions: 1. A toaster draws electric current (electrical energy) from a wall outlet and converts these moving electric charges into heat (thermal energy) in the filaments that turn red hot to cook your toast.
How can you tell if something has kinetic energy?
If an object is moving, then it has kinetic energy. If an object has kinetic energy, then it is moving. … Kinetic energy is the energy possessed by an object due to its motion. If an object is moving, then it has kinetic energy.
What form of energy does a bent ruler have?
So a bent ruler has higher energy than a flat ruler. Now if it is moving it is having an extra form of kinetic energy and thus a flying bent ruler is having higher amount of energy than that of the unbent one.
When a person is sledding down a hill where do they have the most kinetic energy?
At the bottom of the hill, you have the most kinetic energy because you are moving the fastest and all the potential energy has turned into kinetic. Sledding only works when there is snow on the ground, if you try to go sledding on a grassy hill it won’t be as fun because snow helps to eliminate friction.
How do you find potential energy?
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
