5.What is mechanical advantage
doing less work with the same balance of force and distance
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
Explanation / Answer
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.
