mass, m=0.5kg
height, h=20cm = 20/100 = 1/5
Acceleration due to gravity, g=
10m/s^2
work done = force * distance
w= mg*h= 0.5 * 10 *1/5
= 1 Joule

The amount of the work done in raising the glass of the water through a height is calculated by the amount of potential energy
According to the question,
Mass (m) = 0.5 kg
Height ( h ) = 20 cm
1 m = 100 cm
1 cm = 1/ 100 m
20 cm = 20 / 100 m
= 1/5 m
Acceleration due to gravity = 10 m / s ^2 or 9.8 m / s ^2.
Work done = force . distance
From newtons second law :
Force = Mass × Acceleration
W = m g h ( a = g due to gravity )
Putting the values :
W = ( 0.5) ( 10) ( 1/5)
W = ( 0.5 ) ( 2)
W = 1 joule
