Answer to Question #94562 in Mechanics | Relativity for Faris Halim

Question

A block slides down a slope. Assuming there is no friction.
Option A. potential energy is gained at a greater rate than kinetic energy is lost.
Option B. kinetic energy is gained at the same rate as potential energy is lost.
Option C. kinetic energy is gained at a greater rate than potential energy is lost.

Answer 1

According to law of conservation the energy in a closed system remains constant. So true statement is B: kinetic energy is gained at the same rate as potential energy is lost.
