please help me find the potential energy and explain

Answer:
PE ( Potential Energy ) = Mass x Gravity x Height
Explanation:
For the first one you would do.
.28 ( mass) x 9.8 ( constant of gravity ) x .40m ( height )
So just multiply your Mass, Gravity and Height together and you will get Potential Energy
Gravity is always 9.8 m/s
Answer: To find Potential Energy just multiply the mass to accleration due to gravity which is constant (9.8 m/s²) and height or PE =mgh
.Table 1: height is 0.40m
PE1 = 1.1J
PE2= 1.5J
PE3= 1.9J
Table 2: height is 0.32m
PE1= 0.9J
PE2= 1.2 J
PE3= 1.5J
Table 3: height is 0.42m
PE1= 1.2J
PE2= 1.6 J
PE3= 1.98 J
