A plant sits on a windowsill sits 1 story above the ground. A similar plant of the same mass sits on a windowsill 3 story above ground. Which of the following are true.

Question 3 options:

they have the same potential energy


they have the same kinetic energy


the plant 3 stories up has 3x the potential energy


the plant 3 stories up has 9x the potential energy

Answer 1

Potential energy = U = mgh

Where m is mass, g is the gravitational constant, and h is height

What happens to the value of U when h is tripled?

Answer 2

Thank you
