Potential Energy Quizzes Online & Trivia

The item with the most potential energy is the car at the top of the hill, or “A”. Potential energy is the energy that is stored in the item. The item has the potential to do something. There is not much else a car can do at the top of a hill, except going down. A car going down the hill has what is called kinetic energy. Kinetic energy is energy being used to do something. It’s active energy, while potential energy is a passive kind of energy. As the other answer mentions, the equation for figuring out the amount of potential energy in an item is (ug=mgh). This equation can be used to find potential energy, and there is no end to the amount of potential energy an item can have.

It's C. The mass and speed of an object. There are mainly two factors on which Kinetic Energy (denoted by KE) of an object depends - the mass (m) and speed (v) of the object. If the mass and speed of an object will increase, its KE will also increase. The equation which is used to represent the relationship between mass, speed, and KE of an object is as follows: KE = 0.5 • m • v2 where, m = mass in Kilogram (kg) and v = velocity in m/s. This equation also represents that KE is directly proportional to the square of its speed.

Kinetic energy is possessed by an object, by virtue of its movement. It is dependent upon mass and velocity. Potential energy is also affected by its position or state. However, it is more closely linked with forces such as the force of gravity. While kinetic energy of an object is comparable to the state of other objects in its environment, potential energy is completely independent of its environment. Kinetic energy can be conveyed from one object to another. When kinetic energy accelerates, the body maintains unless it speeds up.

Yes, you can. If you are swinging a punch you have created kinetic energy and if you decide to stop that punch in mid-air then you have "destroyed" the kinetic energy that was in the punch.

A ball rolling down a hill would have the greatest kinetic energy. It helps the ball to keep moving down the hill despite all the forces trying to stop it. The energy comes from the forces trying to stop it. The energy comes from the force of gravity, as the object rolls down the hill. If there were an absence of gravity, the object would not fall. When the ball is rolling down the hill, it has kinetic energy. The kinetic energy or driving force of an object is the power it possesses due to its momentum.

A car driving down the hill will have the greatest kinetic energy. Kinetic energy is a concept that is of extreme importance in Physics, and it specifically comes under the domain of classical mechanics or Newtonian mechanics. Kinetic energy can be defined as the energy that is possessed by moving objects. According to physics, energy cannot be created or destroyed, rather it can change its forms from one to another. A moving object with kinetic energy for instance, can lose that energy in the form of sound and heat energy which will dissipate to its surroundings. This ensures the principle of conservation of energy.

The weight on the earth and moon are different. So, the weight obviously will be halved.

What kind of retard comes on these boards and answers a question without providing any sort of explanation for why the answer is what it is. The question is answered for you when you click next..

No work...W = (Fcosθ)d ; W=work, F=force, d=distance/displacement...its prerpendicular so cosine 90° = 0 then multiply so W = 0No Work...
