SSC MTS EXAM

Detailed explanation-1: -Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.

Detailed explanation-2: -Because the mass of a roller coaster car remains constant, if the speed is increased, the kinetic energy must also increase. This means that the kinetic energy for the roller coaster system is greatest at the bottom of the largest downhill slope on the track, typically at the bottom of the lift hill.

Detailed explanation-3: -At the top of the incline, the mass is still at rest, so the Mechanical energy . At the bottom of the incline, the gravitational potential energy, would be all converted to kinetic energy, , where the object has attained its maximum speed.

Detailed explanation-4: -At the bottom of the first hill, kinetic energy is greatest, and this drives the cars up the next hill. The roller coaster cars, the track, the motor that drives the chain that pulls the cars uphill, and Earth’s gravity all work together as a system in which energy changes from one form to another.
