define potential energy derive the equation for potential energy of a body at height h
Answers
Answer:
the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
Expression for Gravitational Potential Energy at Height (h) – Derive ΔU = mgh. When, h<<R, then, R + h = R and g = GM/R2. ⇒ Note: The weight of a body at the centre of the earth is zero due to the fact that the value of g at the centre of the earth is zero.
Explanation:
pls mark brainliest ❤️❤️
When a body of mass (m) is moved from infinity to a point inside the gravitational influence of a source mass (M) without accelerating it, the amount of work done in displacing it into the source field is stored in the form of potential energy this is known as gravitational potential energy. It is represented with the symbol Ug.The equation for gravitational potential energy is:
⇒ GPE = m⋅g⋅h
Where,
m is the mass in kilograms,
g is the acceleration due to gravity (9.8 on Earth)
h is the height above the ground in meters
