If a body weight 10N is lifted from the floor to a table 2m above the floor ,calculate the potential energy gained.What happens to the energy if the body falls of the table and hits the floor?

Answer 1

PE=mgh=10•2=20 J.
PE->KE

Answer 2

P.E=MGH=10*2*10=200J

Answer 3

Pe=mgh
Weight=mass×acceleration due to gravity
10N x height
10N x 2
20J
