Question

7. Write an expression for the potential energy of abody of mass m placed at a height h above theearth's surface. State the assumptions made, if any.​

Answer 1

Answer:

p.e.=1/2mv^2

Explanation:

potential energy is equal to half of mass ×velocity square

Answer 2

Answer:

potential energy=mgh

Explanation:

where m=mass

g=gravity

h=height
