What is the kinetic energy of an object weighing 65 kg dropped from a height of 40m?
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
How do you find the kinetic energy of a falling nickel?
1) measure its mass and velocity. 2) Measure where its falling from. (the kinetic energy will equal the potential energy up to the instant the nickel stops).
Two examples of potential energy converted to kinetic energy?
A stone when it's dropped; and a compressed spring when it's released.
How Kinetic Energy is related to Potential Energy?
Potential and kinetic energy are sort of like inverses. They are not technically inverses strictly speaking in the mathematical sense. Potential energy can become kinetic energy, and vice versa. Keep in mind the mathematical concept of the change in each. (change in) Potential energy= (change in) Kinetic energy. For example, let's say that we had a mass of 1 kg suspended 1 metre above the ground. If we drop it, its kinetic energy by the time it hits the ground is (1/2)mv2 . (1/2)(1kg)(9.82 ) (m2 ) or 48.02J It's potential energy at this point is 0, because it is on the ground and is not suspended in the air. Potential and kinetic energies act as inverses because before the mass was dropped its kinetic energy was 0 and its potential energy was 48.02J. By the time the mass had dropped to the ground however, the potential energy had all transferred into kinetic energy.
What happens to the object's potential energy when it is dropped?
When an object is dropped, its potential energy decreases. This is because potential energy is a result of an object's position or height above the ground. As the object falls, it loses height, which leads to a decrease in potential energy. At the same time, the object gains kinetic energy, which is the energy of motion.
Is kinetic energy a force motion or energy?
Kinetic energy is energy. It can be transformed to other types of energy. And as energy it can be applied to do work. If an elastic ball is dropped from a given height, it will develop kinetic energy at the expense of its potential energy. An instant before collision with the floor, its kinetic energy amounts to the original potential energy of the ball with respect to the floor. (if we can neglect air resistance).

What energy does a marble have when it is dropped?
Kinetic energy is moving energy
What is the energy conversion of a hammer and strikes a nail into a plank?
joule
Which energy transformation that takes place when a ball is dropped to the floor?
Kinetic Energy
What is the kinetic energy of a ball when it is dropped from a height and it falls on a table?
it is the difference of the potential energy when the body is on the table and from the position where it is dropped.
Use the law of conservation of energy to describe what happens to the potential energy of a rock when it is dropped from your hand and strikes the ground?
While falling, potential energy gets converted to kinetic energy (movement energy). Some gets lost to air resistance - that gets converted to heat. Once the rock hits the ground, most of the kinetic energy will be converted to heat.
How do you find the kinetic energy of a falling nickel?
1) measure its mass and velocity. 2) Measure where its falling from. (the kinetic energy will equal the potential energy up to the instant the nickel stops).
Does a baseball have kinetic energy after it has been pitched?
Of course. Any moving object has kinetic energy. In fact, the kinetic energy is at a maximum at the instant the ball is released; it slows down due to air resistance as it goes toward the plate and kinetic energy falls as the square of the reduction in speed.
john lifts a hammer and strikes a nail into a plank. Which of the following energy conversion take place?
bat
What does an object do when it absorbs all light that strikes it?
the atom of the object will gain kinetic energy from the light
How kinetic energy can be transformed into potential energy?
Potential energy is sometimes called the energy of position. This means that it has the ability (potential) to become kinetic energy. A Bowling ball that is held over your head has potential energy. As soon as it is dropped and begins moving, the potential energy begins transforming into kinetic energy.
