What kind of energy transformation takes place when a body is dropped from a certain height? Answer: When a body falls, its potential energy gradually gets converted into kinetic energy. On reaching the ground, the whole of the potential energy of the body gets converted into kinetic energy.
What is energy transformation of a falling body?
As an object falls from rest, its gravitational potential energy is converted to kinetic energy. … K.E. = J, which is of course equal to its initial potential energy.
What kind of energy transformation takes place when a body is thrown up?
However, as the ball moves upward, it slows down as its initial kinetic energy is transformed into potential energy. … When a ball is thrown straight up into the air, all its initial kinetic energy is converted into gravitational potential energy when it reaches its maximum height.
When a body falls from a certain height its potential energy gradually changes into?
When the body falls from a height, its potential energy changes into kinetic energy progressively. A decrease in the potential energy is equal to an increase in the kinetic energy of the body. During the process, the total mechanical energy of the body remains conserved.
What kind of energy transformation takes place at the object is falling towards Earth?
The gravitational potential energy an object has at the start of a fall is converted into kinetic energy as it falls, and this kinetic energy goes into producing sound, causing the object to bounce, and deforming or breaking the object as it strikes the ground.
Is energy conserved in free fall?
is a conserved quantity: i.e., although the kinetic and potential energies of the mass vary as it falls, its total energy remains the same. The mks unit of energy is called the joule (symbol J). …
Which energy takes place when work is done?
There is also energy in the process of transfer from one body to another i.e. heat and work. Once energy is transferred it’s always designated according to its nature. Therefore, Thermal energy may result from the transfer of heat and work done may take the shape of mechanical energy.
What kind of energy transformation takes place when?
Electric generator (Kinetic energy or Mechanical work → Electrical energy) Fuel cells (Chemical energy → Electrical energy) Battery (electricity) (Chemical energy → Electrical energy) Fire (Chemical energy → Heat and Light)
When a ball is thrown upwards energy is transformed into energy?
When a ball is thrown upwards, kinetic energy is transformed into potential energy.
What is the kinetic energy of freely falling body?
In the case of a freely falling body, it is the mechanical energy of the system that is conserved. Mechanical energy (E) is the sum of the potential energy (U) and the kinetic energy (K) of the freely falling body. Therefore, E=K+U=constant.
When energy changes from one from to another there is no loss or gain of energy?
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.
When a body falls its kinetic energy remains constant?
Explanation: Since, total energy of the system is always conserved, so when a body falls freely towards the earth, then its total energy remains constant i.e., the sum of the potential energy and kinetic energy of the body would be same at all points.
