If the potential energy of an object is 245 J and its height is 5 meters, what is its mass?

Using the formula $$m = \frac{PE}{gh}$$ : $$m = \frac{245 \, \text{J}}{9.8 \, \text{m/s}^2 \times 5 \, \text{m}} = 5 \, \text{kg}$$ .

What does the variable 'g' represent in the potential energy formula?

The variable 'g' represents the acceleration due to gravity, which is approximately $$9.8 \, \text{m/s}^2$$ on the surface of the Earth.

What is the significance of height in potential energy calculations?

Height is significant in potential energy calculations because it determines how much energy is stored due to an object's position above the ground. The higher the object, the greater the potential energy.

How does mass affect potential energy?

Mass directly affects potential energy; the greater the mass of an object, the more potential energy it has at a given height, as indicated by the formula $$PE = mgh$$ .

What happens to potential energy if the height is doubled?

If the height is doubled, the potential energy also doubles, assuming mass remains constant, because potential energy is directly proportional to height in the formula $$PE = mgh$$ .

Can potential energy be negative?

Potential energy is typically considered to be zero at ground level. It can be negative if measured relative to a reference point below ground level, but in most practical scenarios, it is non-negative.

What is the unit of measurement for potential energy?

The unit of measurement for potential energy is the Joule (J).

How can potential energy be converted to kinetic energy?

Potential energy can be converted to kinetic energy when an object falls or moves downward, transforming the stored energy into motion as it descends.
