This is the answer: 62 x 9.8 x 12= 7 291.2! Hope this is helpful!
Use the formula potential energy = mgh (mass x gravity x height), mass in kilograms, gravity about 9.8 (meters per square second), height in meters. Answer will be in Joules.
Energy is measured in Joules, not in Watts. Watts is a unit of power, and is equal to Joules / second. To calculate the potential energy (in Joules), convert the units to SI units (lbs to kilograms, feet to meters), then use the formula potential energy = mass x gravity x height. Use 9.8 meters per second square for gravity. A2: The Energy to lift 1000 # 10 feet is 10kft# or 40/3 k Joules.
A joule is a neuton metre. i.e. 10*5 = 50 joules are required.
Work is force x distance = 700 x 4 = 2800 Joules

2000 joules
Joule is a unit for measuring energy. Meter is a unit for measuring length or distance. There is no conversion. If you wanted to find the potential energy of an object, 2.04 meters off the ground, then you would need to know the mass of the object and the value of g (gravitational acceleration) at the point where you are, then you could calculate energy in Joules.

A 1-newton book at 4 meters gains approximately 4 joules of potential energy.
Use the formula PE = mgh (potential energy = mass x gravity x height). If mass is in kilograms, gravity in meters/second2 (the value is about 9.8), and the height is in meters, the answer will be in joules.
56 kilo joules = 56,000 joules
