Pls pls help will b forever grateful A student does an experiment to compare the potential energy of a block sliding down a ramp. He calculates the gravitational potential to be 150 J. However, the kinetic energy at the bottom was calculated to be ONLY 100 J. Why wasn't energy conserved in this situation?

Question 6 options:

The car's weight increased as it slided down the ramp.

The student pushed the car at the top rather than releasing it from rest.

The student gave an incorrect measurement for the ramp that was too BIG.

The student did NOT account for the friction converting some of the object's kinetic energy into heat.
