find the potential energy of a 3kg block that is on a roof top 10m above the floor.
To find the potential energy of an object, you need two important pieces of information: the mass of the object (m) and the height from which it is dropped (h). In this case, we have a 3 kg block that is on a rooftop 10 m above the floor.
The formula to calculate the potential energy is:
Potential Energy (PE) = mass (m) × acceleration due to gravity (g) × height (h)
Acceleration due to gravity (g) is approximately 9.8 m/s^2 on Earth.
Now, let's plug in the values into the formula:
PE = 3 kg × 9.8 m/s^2 × 10 m
Simplifying the equation:
PE = 294 J
Therefore, the potential energy of the 3 kg block on the rooftop 10 m above the floor is 294 joules.
