doing the same work with the same balance of force and distance

doing more work with less balance of force and distance

doing the same work with a different balance of force and distance

Answer 1

1. Potential; kinetic - Stored energy is called potential energy and energy in motion is kinetic energy.

2. Bernoulli's Principle - It states that sum of potential energy, kinetic energy and pressure energy remains conserved for a fluid. When a ball rotates, air gets dragged along it creting a velocity difference which leads to a pressure difference that creates a force that curves the path.

3. had three previous versions - It is short form of 4th Generation and hence it succeeds 1st, 2nd and 3rd generation.

4. the compression of water - Pascal's law relates to transmission of pressure over a fluid and would determine amount of compression.

5. doing the same work with a different balance of force and distance - We have the same work considering law of conservation of energy. As Work = Force x Distance. We can choose a lower force and a higher distance and vice versa.
