Q1. IT IS POSSIBLE TO ACCELERATE MOTORCYLCLE WITHOUT PUTTING HIGHER PETROL INPUT RATE INTO THE ENGINE. MOREOVER MOTORCYCLE IS DRIVEN ON A HORIZONTAL ROAD.
Q2. A SMALL COIN IS PLACED ON A REORD ROTATING AT 94/3 REV/MINUTE. THE COIN DOESNOT SLIP ON THE RECORD.WHERE DOES IT GET THE REQUIRED CENTRIPETAL FORCE FROM?

Expert Answer
Increase in Acceleration leads to increase in force and increase in workdone/Energy.
Hence increase in energy requires more input energy.
So it is not possible to accelerate without putting higher petrol input rate to engine
