Question

Write the various types of potential energy. Explain the formulae.

Answer 1

(a) U = mgh

U – Gravitational potential energy

m – Mass of the object,

g – acceleration due to gravity

h – Height from the ground,

(b) u = `1/2"K" "x"^2`

u – Elastic potential energy

k – String constant;

x - displacement.

(c) U = `1/(4piepsilon_0) . (q_1q_2)/r`

U – electrostatic potential energy

ε₀ = absolute permittivity

q₁, q₂ – electric charges
