What is the potential energy of a 3kg ball that is on the ground.
-do i do mgh?
(9.8)(3kg) ?
Yes, to calculate the potential energy of an object, you can use the formula mgh, where m is the mass of the object, g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth), and h is the height or vertical distance of the object from a reference point.
In this case, since the ball is on the ground, the height (h) is zero. Therefore, the potential energy of the ball would be:
Potential energy = (mass) × (gravity) × (height)
Potential energy = 3 kg × 9.8 m/s^2 × 0 m
Since the height is zero, the potential energy of the ball would also be zero.
