Question

E
Learning Task No. 4: Determine if the given situation shows potential or kinet-
ic energy. Calculate using the formula given below.
P.E. = mass x acceleration due to gravity x height
P.E. = mgh= Nxh acceleration due to gravity = 9.8 m/s2 or 10m/s2
1 Newton (N) = 1 kg x 1 m/s2 or 1 kg m/s2
KE = 1/2 mv2
