A high board is a diving board used in the sport of swimming.
The change in energy of a person jumping off a rigid diving board is from potential energy at the top to kinetic energy at the bottom. At the top, the person has potential energy due to their height above the ground, which is converted to kinetic energy as they fall towards the ground.
Yes, a diving board can be considered a type of lever. When a person jumps on the diving board, it bends and stores potential energy. As the person pushes off, the board straightens, releasing the stored energy and propelling the person into the water.
Jumped
The gravitational force acting on you at the top of the diving board gives you more potential energy than you had on the ground. As you climb up, the higher position increases your gravitational potential energy because you are further away from the ground. This potential energy can be converted into kinetic energy when you jump off the diving board.
There is cliff diving and BASE jumping.
When a person jumps off a diving board, the force pushing the person upward (reaction force) is caused by the person pushing down on the diving board (action force). The reaction force is equal in magnitude and opposite in direction to the action force, according to Newton's third law of motion.
The resistance of water when jumping off a diving board is called drag, and it is caused by the water's viscosity and density. Drag opposes the motion of the diver, making it harder to move through the water and causing the sensation of resistance.
The reaction force to Earth's gravity is the diver's weight pushing down on the diving board. This force is equal in magnitude and opposite in direction to the force of gravity acting on the diver.
Diving board I think
While he's in the air, the reaction force is air resistance and when he's in the water the reaction force is upthrust. Hope this helps.
