Question

The diagram below is a representation of a roller coaster for a set of cars that are moving from position 1 to 2.

As the cars move form position 1 to 2, their……………………………………decreases while their ……………………..remain unchanged.

Answers

Total energy and Velocity
correct

KE and PE + KE
PE + KE and total energy
Velocity and total energy

Explanation

According to the conservation of energy principle, energy can only be changed from one form to another; it cannot be generated or destroyed. Understanding this theory is essential to comprehending how a roller coaster's motion is controlled.
Because of its height above the ground, the roller coaster has gravitational potential energy at the start of the ride. This potential energy is transformed into kinetic energy as it descends.
A portion of the kinetic energy of the coaster is transformed into several forms as it travels over the track. These forms include air resistance, acoustic energy produced by the coaster's movement, and heat energy from friction between the wheels and the track. Still, the system's total mechanical energy—which is the sum of its kinetic and potential energy—remains.
