mgh = 10 x 10 x 10 = 1000 J ( Assume g value as 10 m/s2
To calculate gravitational potential energy, use the formula PE = mgh (potential energy = mass x gravity x height). Use 9.8 for gravity. Answer is in Joule.
Its height is two meters.
1,000
Potential energy = mg * h Given mg = 25 N and h = 3 m So required potential energy = 75 J
For an object to require potential energy a force must be acting on it in a certain direction. Even though the object doesnt move doesnt mean it has potential energy. The most common force of otential energy is Gravity. When an object is lifted off the ground gravity becomes stronger. For a formula of proof then use E=FxD (Energy=Force applied x Distance travelled). If a ball has been lifted by 10 Meters with a force of 500 Newtons then it has a Potential Energy of 5000 Newton Meters,
After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.

PE = m g H = (0.025) (9.8) (5) = 1.225 joule
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

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.
Force x distance = 100 x 2 = 200 newton-meters = 200 joules.

Let's see. First.....,F = mam = F/am = 4 N/9.8 m/s2= 0.408 kilograms----------------------m = 5 N/9.8 m/s2= 0.510 kilograms-----------------------------secondly......,PE = mghPE = (0.408 kg)(9.8 m/s2)(3.0 meters)= 11.99 Joules==============A 4 Newton object lifted 3 meters gains more potential energy.
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
The object's potential energy is 6,664 joules.
The ball's potential energy at 0.8 meters is 3.92 joules.
work is equal to a change in energy. in this case there is a change in potential energy. potential energy = mass x gravity x height E(p)=mgh E(p)= 3x9.8x40 E(p)=1176 J thus there is a change in potential energy of 1176 joules and since W=change E(p) Work done is 1176 J
