Worked practice questions
As per your syllabus, the zero of GRAVITATIONAL potential energy is conventionally chosen at which level?
- The ground (reference)
- The launching height
- Infinity always
- The centre of Earth
Show answer and solution
Correct answer: A. The ground (reference)
syllabus Points 7: for mgh form, zero is taken at ground level.
PE is defined up to an additive constant.
As per your syllabus, an object dropped from height h, just before hitting the ground, has kinetic energy equal to which value?
- (1/2) m g h
- 2 m g h
- m g h / 2
- m g h
Show answer and solution
Correct answer: D. m g h
Your syllabus: all gravitational PE = mgh has converted to KE on impact ⇒ K = mgh.
