An object is thrown into the air. Which graph shows how the gravitational potential energy Eₚ of the object varies with height h above the ground?

Q: What topic does this question test?

This question tests Work, energy and power in A-Level Physics (syllabus code 9702). It is worth 1 mark.

Agraph showing gravitational potential energy Eₚ increasing linearly with height h from 0.

Bgraph showing gravitational potential energy Eₚ decreasing linearly with height h.

Cgraph showing gravitational potential energy Eₚ increasing and then decreasing with height h, forming an inverted parabola.

Dgraph showing gravitational potential energy Eₚ decreasing and then increasing with height h, forming a parabola.

✓ Correct Answer

The correct answer is A: graph showing gravitational potential energy Eₚ increasing linearly with height h from 0.
