State law of conservation of energy. Explain on the basis of law of conservation of energy, the energy transformation that takes place when a stone of mass m is thrown vertically upwards and it attains a height h metre and then attains a speed of v on striking the ground.
Answers
Answer:
ok well it is easy and will try to explain u theoratically
well THE LAW OF CONSERVATION OF ENERGY STATES THAT ENERGY CAN NEITHER BE CREATED OR DESTROYED BUT IT CAN BE TRANSFORMED FROM ONE MEAN TO ANOTHER
NOW SUPPOSE IF 2 THINGS ARE THEIR AND THEY ARE RUBBED WHAT WILL HAPPEN .... THERE WOULD BE FRICTION MORE OVER THE PARTICLE WILL INTERECT MORE THERE WILL BE DISTURBANCE IN THE QUARKS WHICH PRODUCE ENERGY
UR 2ND ANSWER
LET THE MASS OF THE STONE BE X AND WE THROW IT AT A CERTAIN HEIGHT THEN THERE WOULD BE POTENTIAL ENERGY AND WE CAN FIND IT BY APPLYING FORMULA MASS * GRAVITATIONAL FORCE * HEIGHT

Law of Conservation of energy :
According to the law,
Energy can neither be created nor destroyed; it can only be transformed from one form to another
Kinetic energy is the energy gained by a body due to its velocity and the potential energy is the energy gained by an object due to its height.
When you throw a stone, you give it a velocity thereby making it gain Kinetic Energy. When it is at the top or the maximum height it can reach, its Potential energy is the highest and its Kinetic energy is 0. When it is attracted back towards the ground, it gains velocity and thus Kinetic energy and loses Potential energy (losing the height). At the lowest point before hitting the ground, Kinetic energy is the highest and the potential energy is lowest. During all this process the total mechanical energy of the body remains constant. Mechanical energy is the sum of Kinetic energy and the Potential energy.
