Answer:
The two different ways to measure gravitational potential energy is listed below:
Explanation:
- To measure the gravitational potential energy of the ball dropped from certain height we can use the formula as:
PE= mgΔh
where,
m= mass of the ball
g= gravity
Δh= change in height
- The second way is to follow the principal as:
Loss in PE = Gain in KE
∴ -ΔPE = ΔKE
- Height and mass is the major element that determines the gravitational potential energy of any object.
Answer:
If the sun's mass were to double without pushing or pulling on the Earth, then the Earth's orbit will change to an ellipse which brings it out to our current radius but spends most of its time closer to the sun. The tides would probably get even stronger then, particularly when our orbit takes us closer to the sun.

Answer:
A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
