Mechanical Energy
Energy in an object which can create some motion in the object is known as mechanical energy. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. There are two forms of mechanical energy that is kinetic energy (energy due to motion) or potential energy (energy due to the position). Mechanical energy of an object can be calculated as the sum of the kinetic energy and the potential energy of an object.
Kinetic energy :
Energy possessed by a body by virtue of its state of motion is called kinetic energy. A moving bus, a rolling ball are some examples of kinetic energy.
Potential energy :
Energy possessed by an object due to its position is called as potential energy. A stretched rubber band, a catapult are some examples of potential energy
For example :
The kinetic energy of an aeroplane at rest is zero. As the aeroplane is standing at the ground level its potential energy is zero on the ground. Then, its mechanical energy which is the sum of kinetic energy and potential energy is zero while it rests on the ground. When the same aeroplane flies, it has kinetic as well as potential energy. Their sum gives the aeroplane's mechanical energy in flight.
Conservation of Mechanical Energy :
The total mechanical energy of a system is conserved i.e. energy can neither be created nor destroyed , it can only be converted from one form to other.
K.E. + P.E. = constant

Students / Parents Reviews [10]
My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.

8thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
Shivam Rana
7thA marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.

7thIt has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice

10thIt was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
Cheshta
10thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
Hiya Gupta
8thAbhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.
Manish Kumar
10thIt was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
