Whether it has (gravitational) potential energy or not depends on what level you (arbitrarily) define as zero. If you define the bottom of the ledge as the "zero" level, then the top of the ledge will have positive energy. If you define the top of the ledge as the "zero" level, then the object on the top of the ledge will have zero potential energy (and at the bottom of the ledge it will have negative potential energy). In any case, at the top of a ledge, an object will have more potential energy than at the bottom of the ledge, because it requires work to push the object up; also, in principle the potential energy can be recovered (converted to some other type of energy) if the object falls down.
What else can I help you with?
Calculate the potential energy of a 5 kg object sitting on a 3 meter ledge?
The equation to use here is Epotential=mgh.Using your given values, and assuming the acceleration due to gravity to be 9.81ms-2, the potential energy can be found to be 147 Joules.
A rock balanced on a ledge has what kind of energy?
The rock balanced on a ledge has potential energy due to its position above the ground. If it falls, this potential energy will be converted to kinetic energy as the rock moves downward.
Book on a shelf potential or kinetic energy?
Carry it up a cliff. ************************** Increase the height of the object or increase the mass.
What is the potential energy 5 kg object sitting on a 3 meter ledge?
6.0kgm2/s
A flowerpot falls from a ledge 50 m above the ground. compare the potential and kinetic energy when it is at 25 m above the ground to its original potential and kinetic energy?
After falling 25 meters, it has less potential energy, by an amount calculated with the formula mgh (mass x gravity x height). If you ignore air resistance, the kinetic energy will increase by the same amount.
What is an example of only potential energy?
A ball sitting at the top of a ledge, it has a lot of potential energy until it is pushed off the ledge then it is converted into kinetic energy

What is the gravitational potential energy of a person with a weight of 600 N that is standing on a ledge that is 25 m up on the air?
PE = w*h = 600*25 = 15000 joules or 1.5 kJ

A boulder with a mass of 2500 kg on a ledge 200 m above the ground falls what is the speed of the boulder just befor it hits the ground?
According to Eculator's calculator for velocity of a falling object, the speed of the boulder won't be dependent on its mass and will be given by:v = (2gh)1/2So, the calculated answer putting h = 200 m would be: 62.609903369994115 m/sec
Why shouldn't you place heavy objects on the ledge behind the passenger seat while driving a car?
Any unsecured item in a car has the potential to become a projectile. In an accident where the front of the vehicle impacted an object, there is every chance that a heavy item placed on the ledge behind the passenger's seat would fly forwards like a missile and hit the passenger in the back of the head.
Five example of potential energy?
-hanging apple -the energy that is stored in our cells of our body -when we stretch a rubber band -the water at the middle at the tap -a football at the table 1. Apple on a table 2. Spring of a watch 3. You sitting on a Chair 4. a ball floating on a water column 5 Apple hanging on a tree A rock next to a ledge. A wound up spring. A turned off faucet. An unpopped balloon. unexploded dynomite
Which has more potential energy a 10 kg box rolled on a 5 meter long ramp up to ledge or a 10 kg box rolled up a 20 meter long ramp?
The potential energy that the box gained only depends on how high it was raised, not on how it got there. If both boxes started at the same height and ended at the same height, then they both gained the same amount of potential energy.
Where do you find Wendy in Kingdom Hearts?
In the ship she is hidden in a room. You need to be able to fly to reach her. After you're at the clock tower, she is sitting on the ledge.
