Question

Lamar writes several equations trying to better understand potential energy. H = d with an arrow to the equation W = F d and P E Subscript g Baseline = m g h. F Subscript g Baseline = mg with arrows to the F in W = F d and to P E Subscript g Baseline = m g h. What conclusion is best supported by Lamar's work? The elastic potential energy is the same for any distance from a reference point. The gravitational potential energy equals the work needed to lift the object. The gravitational potential energy is the same for any distance from a reference point. The elastic potential energy equals the work needed to stretch the object.

Answer 1

Answer:

The gravitational potential energy equals the work needed to lift the object.

Explanation:

here we know that

$H = \vec d$

work done is given as

$W = \vec F . \vec d$

Potential energy is given as

$PE_g = mgh$

force due to gravity is given as

$\vec F_g = mg$

now here if we plug in the value of distance and force in the formula of work done then we will have

$W = (mg)(h)$

so here we got

$W = PE_g$

so we can concluded that

The gravitational potential energy equals the work needed to lift the object.
