when the friction is increased.
When there is no object at all.
Explanation / Answer
1. Faraday: The Law of electromagnetic induction was given by Faraday.
2. Bernoulli's Principle: Speed of air on two sides of a spinning ball is different. This leads to a pressure difference that provides the force that curves the path.
3. Used in Tesla cars: Superconductive wires carry current with negligible power loss or heat generation. This makes them capable of carrying large amounts of current efficiently to power the car motor.
4. Changes gears: Derailleur is part of the gear system that helps movement from one sprocket to the other.
5. When stored energy becomes the energy initiating a motion- This is because Potential energy is a stored form of energy and Kinetic energy is the energy of motion.
