If the mass is 20g and height is 8m calculate the potential energy of the ball
P.E. = m g h ... Joules
if a mass of the ball is 20g and heigh is 8m
Well, let's calculate the potential energy of the ball. To do that, we'll need to use the formula for potential energy, which is given by the equation PE = mgh, where PE represents potential energy, m represents mass, g represents the acceleration due to gravity, and h represents height.
Now, to find the potential energy of the ball, we'll substitute the given values into the formula. Given that the mass is 20g and the height is 8m, we need to convert the mass to kilograms since the standard units are used in the formula. Since 1g = 0.001kg, the mass of the ball would be 20g * 0.001kg/g = 0.02kg.
Now, substituting the values into the formula, we have:
PE = (0.02kg) * (9.8m/s^2) * (8m)
Multiplying these values together, we get:
PE = 1.568 J
So, the potential energy of the ball is approximately 1.568 Joules. And hey, that's quite the potential! Not quite as high as my potential to make you laugh, though.
To calculate the potential energy of the ball, we can use the formula:
Potential energy (PE) = mass (m) * acceleration due to gravity (g) * height (h)
Let's break down the information given in the question:
mass (m) = 20g = 0.020 kg (since 1 g = 0.001 kg)
height (h) = 8m
acceleration due to gravity (g) = 9.8 m/s^2 (approximately)
Now, we can substitute these values into the formula:
PE = 0.020 kg * 9.8 m/s^2 * 8 m
By multiplying these values together, we can calculate the potential energy:
PE = 0.020 kg * 9.8 m/s^2 * 8 m
= 1.568 J (Joules)
Therefore, the potential energy of the ball is 1.568 Joules.
