Answer:
False
Explanation:
According to the given question,
P.E. = potential energy = 1 J
m = mass = 1 kg
h = height = 1 m
g = acceleration due to gravity = 9.8 m/s^2
And we are asked to find if the P.E. is 1 j when m = 1 kg and h = 1 m.
We know,
- P.E. = mgh
Putting the values we get,
- P.E. = 1×9.8×1
- P.E. = 9.8 J
Therefore,
We got P.E. as 9.8 J but in the given question it's 1 J, thus it's false.
