PE = m g H = (0.025) (9.8) (5) = 1.225 joule
Potential energy = m G H = (100 kg) (9.8 m/s2) (10 m) = 9,800 kg-m2/s2 = 9,800 joules9,800 joules is the correct answer to this question
mgh = 10 x 10 x 10 = 1000 J ( Assume g value as 10 m/s2
I believe that when you say 'lifted through', you mean lifted to a height of 10m. If so, the amount of work is such: Work= Force x Distance which have the units (Joules = Newtons x meters) When the object is lifted, it increases in its potential energy. The equation for this is: Potential energy = mass x gravitational force x height = 4.5 x 9.81 x 10 =441.45 Joules As 1 joule = 1 newton x meters and we have 441.45 Joules, 441.45 joules of works is done! :D
Potential energy = mg * h Given mg = 25 N and h = 3 m So required potential energy = 75 J
The book's potential energy is 294 joules.
Use one of the formulas for constant acceleration to calculate how many meters the brick will fall after 2 seconds. Subtract this from the 30 meters, to see how high the brick is above ground. Finally, use the formula for potential energy: PE = mgh, to calculate the potential energy.

The object's potential energy is 6,664 joules.
The ball's potential energy at 0.8 meters is 3.92 joules.

That depends what kind of "potential energy" you are talking about, but without further specification, this usually refers to gravitational potential energy. The formula for gravitational potential energy is PE = mgh, that is, mass x gravity x height. If mass is in kg. and gravity in meters per second square (use the value 9.82 for Earth's gravity), and height in meters, then the energy will be in Joule.That depends what kind of "potential energy" you are talking about, but without further specification, this usually refers to gravitational potential energy.

That is potential energy in inch pounds or Newton-meters
Potential energy = mg * h Given mg = 25 N and h = 3 m So required potential energy = 75 J
The potential energy (PE) is 110.93 Joules, using 9.8 as the acceleration of gravity.
The book's potential energy is 294 joules.
Depends what potential energy you mean. Without an additional qualifier, "potential energy" frequently refers to gravitational potential energy. This is calculated as mass x gravity x height. If you want to use standard (SI) units, mass is in kg., gravity in meters per second square (the value is about 9.8, if you are close to the Earth's surface), and height in meters. The result is in Joule.Depends what potential energy you mean. Without an additional qualifier, "potential energy" frequently refers to gravitational potential energy.
