The reaction force to Earth's gravity on the diver is the gravitational attraction that the diver exerts back on Earth. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, the Earth pulls the diver down, and the diver also pulls the Earth up with an equal force.
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.
After the diver jumps forward from the diving board, the force of gravity will act vertically downwards, accelerating the diver towards the water. The forward motion of the diver will continue unless another force, like air resistance or the water, acts in the opposite direction to slow them down.
Gravity always acts as a pair of forces, not as one single force. The strength of the forces depends on both masses, not just one of them. The forces of gravity attract the diver toward the earth and the earth toward the diver. The forces are equal in both directions. If the diver weighs 150 pounds on earth, then the earth weighs 150 pounds on the diver. The diver accelerates toward the center of the earth with an acceleration equal to (weight)/(diver's mass), and the earth accelerates toward the diver with an acceleration equal to (weight)/(earth's mass). Has that helped, or just confused the issue further ?
Yes, the diver at the top of the diving board has potential energy due to their position above the ground. Once the diver jumps, this potential energy is converted to kinetic energy as they accelerate towards the water.
A diving board is a first-class lever, with the fulcrum located at one end and the input force (diver's weight) applied to the other end to produce the output force (diver launching into the water).

Diving boards illustrate Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. When a diver jumps off a diving board, they push down on the board with force (action), causing the board to bend and then push back up (reaction). This upward force propels the diver into the air. Thus, the interaction between the diver and the board exemplifies this law through their mutual forces.

The diver at the top of a diving board has potential energy
When the diver jumps up on the diving board, the board experiences tension as it bends upwards. As the diver lands back on the board, it experiences compression as it bends downwards. These alternating tension and compression forces act together to provide the necessary rebound for the diver to propel themselves into the air.
