125 pounds lifted 8 ft what is the potential energy?
The potential energy can be calculated using the formula: Potential Energy = mass x acceleration due to gravity x height. Converting 125 pounds to mass (56.7 kg), the potential energy would be 438.3 joules.
At what point PE at a maximum?
The potential energy of an object is at a maximum when it is at its highest point in a gravitational field, such as when it is lifted to its maximum height or at the peak of a motion like a swing. At this point, all of its energy is in the form of potential energy due to its position relative to the Earth's surface.
Explain how the maximum height is related to the maximum potential energy?
This question makes sense in the context of something like a pendulum. At the top of its swing, a pendulum is at maximum height, is not moving and so has zero kinetic energy, and has maximum potential energy since all its energy is potential. As it falls, it gradually moves with increasing speed, so its potential energy is being converted to kinetic energy. At the bottom of the swing, it is moving at maximum speed, and all its energy is kinetic, none is potential, Then it starts to move upwards again, and its kinetic energy is gradually converted back to potential energy.
Why is potential energy is defined in massxgravityxheight?
Potential energy is defined as mass × gravity × height because it represents the energy stored in an object due to its position above the ground. The mass accounts for the quantity of matter, gravity represents the acceleration due to gravity, and height indicates the distance the object is lifted from the ground. Multiplying these factors provides a measure of the potential energy stored in an object when it is raised to a certain height.
When in a roller coaster ride does potential energy become kenetic energy?
Potential energy becomes kinetic energy when the car begins its downward descent from the top of one of the rollercoaster's peaks. It accumlates potential energy as it is lifted to the first and highest peak. It regains some of its lost potential energy each time it re-ascends one of the lower peaks, then loses potential and gains kinetic energy as it drops again.
When an object is lifted 6 feet off the ground it gains a certain amount of potential energy If the same object is lifted 12 feet off the ground its potential energy is?
When an object is lifted 6 feet off the ground, its potential energy is a certain value based on its height and mass. If the same object is then lifted 12 feet off the ground, its potential energy will be doubled compared to when it was lifted 6 feet. This is because potential energy is directly proportional to the height to which the object is lifted.
A car is lifted a certain distance in a service station and therefore has a potential energy relative to the floor If it were lifted twice as high how much potential energy would it have?
If the car is lifted twice as high, its potential energy would be four times as much. Potential energy is directly proportional to the height to which an object is lifted, so doubling the height would result in a quadrupling of potential energy.
When an object is lifted 10m it gains a certain amount of potential energy If the same object is lifted 20m its potential energy gain is?
The potential energy of an object is directly proportional to its height above the ground. So, if the object's potential energy increases by a certain amount when lifted 10m, it will increase by twice that amount when lifted 20m.
What happens to potential energy as the object is lifted higher?
As an object is lifted higher, its potential energy increases. This is because the object gains potential energy due to its increased height above the ground, resulting in a greater potential to do work when released.
What is the relationship between height and potential energy?
The relationship between height and potential energy is that the potential energy of an object increases as its height above the ground increases. This is because the higher an object is lifted, the more gravitational potential energy it has due to its increased distance from the Earth's surface.
How do you calculate energy input for lifting objects by weight and height lifted?
When an object is lifted to a certain height, the mechanical energy of the person or system lifting the object gets transferred into the potential energy of the object. Thus if an object of mass/weight 'm' is lifted to a height 'h', then the potential energy possed by the object at height 'h' is given as: Potential Energy (P.E)= m*g*h, where g is acceleration due to gravity and whose value is 9.8 m/s2.
How can you make a bowling ball and soccer ball have the same gravitational potential energy?
You can make the bowling ball and soccer ball have the same gravitational potential energy by lifting them to the same height above the ground. Gravitational potential energy depends on the mass of the object and the height it is lifted, so as long as both balls are lifted to the same height, they will have the same gravitational potential energy.
What kind of energy is stored by height?
Potential energy is stored by height. The higher an object is lifted, the greater potential energy it possesses due to its elevated position relative to the ground. This potential energy can be converted into kinetic energy as the object falls.
On which body would a 30 kg bowling ball have the least gravitational potential energy when lifted to a height of 1 m?
The bowling ball would have the least gravitational potential energy when lifted to a height of 1 m on the moon, as the moon has less gravitational pull compared to Earth. This means that the gravitational potential energy of the ball is lower on the moon than on Earth when lifted to the same height.
When does an object have gravitational potential energy?
Well gravitational potential energy is potential energy that depends on the height of an object so an object would have gravitational potential energy when ever it's of the ground or at a high height (it doesn't have to be very high) for example if you lift up a ball it has the potential to fall or if your climbing a mountain you have gravitational potential energy.
Which of these would you expect to most influence the potential energy of an object?
The height above the ground and the mass of the object are the main factors that influence the potential energy of an object. As an object is lifted higher above the ground, its potential energy increases due to gravity. Additionally, the more mass an object has, the greater its potential energy will be when lifted to a certain height.
What is the relationship between the potential energy on a pendulum and the value of mass height and gravity acceleration?
The potential energy of a pendulum is directly related to the mass of the object, the height at which the object is lifted, and the acceleration due to gravity. The potential energy increases with the mass of the object, the height to which it is lifted, and the strength of the gravitational field. This relationship is described by the equation for gravitational potential energy: PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height.
