ENERGY

Question 1

ability to do work

Answer 1

energy

Question 2

energy of body due to its position or shape

Answer 2

potential energy (pe)

Question 3

formula of gravitational pe (GPE)

Answer 3

GPE = mgh

m - mass
g -gravitational field
h - height

Question 4

formula of elastic pe (EPE)

Answer 4

EPE = 1/2 kx^2

k - spring constant
x - displacement of spring

Question 5

energy of a moving body

Answer 5

kinetic energy

Question 6

formula of kinetic energy

Answer 6

KE = 1/2 mv^2

m - mass
v - velocity

Question 7
