Potential energy : energy obtained due to height or position (the force of gravity)

PE = mhg

g = acceleration due to gravity (m/s²)

h = height (m)

m = mass (kg)

1. Known

m = 0.5 kg

h = 1 m

g = 9.8 m/s²

then :

$\tt PE=0.5* 1* 9.8=4.9~J$

Kinetic energy is the energy gained by an object's motion

KE = 1/2 mv²

2. To find KE, the required data are the mass and velocity

in this table, you do not display the velocity
