write few daily life examples in which you observe conservation of energy
Answers
Two football players collided on the field, and both went flying backwards. Energy was transferred from each player to the other, sending them in the opposite direction from which they had been running.
Claire threw the ball and it hit her mother's vase, knocking it over. Energy was transferred from the moving ball to the stationary vase, causing the vase to move.
Fingers hitting piano keys transfer energy from the player's hand to the keys.
Billy hit the punching bag, transferring energy from his arm to the stationary bag.
The dog ran in into the Christmas tree and knocked it over. Energy was transferred from the moving dog to the stationary tree, causing the tree to move.
When the car hit the road sign, the sign fell over. Energy was transferred from the moving car to the stationary sign, causing the sign to move. No energy was lost in the transfer.
Potential energy of oil or gas is changed into energy to heat a building.
Answer:law of conservation of energy means Energy is neither created nor destroyed only it can changed from one form to another form.
Examples of the law of conservation of energy are:
1)When we turn on the light we give electrical energy to the bulb it convert that energy into light and heat energies
2)In 8 ball pool game when hit the ball the ball has kinetic energy,when this ball hits the other ball at rest it also starts to move means with the kinetic energy in the ball it made to move the other ball by transfering some of its energy
3)when we throw a ball upwards the ball has initially kinetic energy and afterwards this kinetic energy converts into potential energy.
4) In hydro electric power plant water falls from height and convert that potential energy to kinetic energy and this kinetic energy in to electrical energy.
5)when we rub our hands mechanical energy converts in to heat energy.
