gravitational potential energy:
Explanation:
The gravitational potential energy of an object can be calculated with the formula:
color(blue)(|bar(ul(color(white)(a/a)color(black)(E_g=mgh)color(white)(a/a)|)))
ul("where") :
E_g= gravitational potential energy
m= mass
g= acceleration due to gravity
h= height
To find the gravitational potential energy of the object, substitute your known values into the formula.
E_g=mgh
E_g=(9kg)(9.81m/s^2)(4m)
E_g=353.16J
Rounding off to one significant digit,
E_g~~color(green)(|bar(ul(color(white)(a/a)400Jcolor(white)(a/a)|)))
