Concervation Of Energy Snd Energy Transfers Flashcards
1
Q
What is the conversation of Energy principles
A
Energy can be transferred usefully, stored or dissipated, but never be created or destroyed
2
Q
How is a ball thrown in the air a example of mechanical energy
A
It’s from the chemical energy store of the persons arm to the kinetic energy stores of the ball and arm
3
Q
How is a ball dropped from a height a example of mechanical energy
A
Ball accelerates from the constant force of gravity. Energy transferred from the balls gravitational potential energy store to its Kinetic energy
4
Q
How is a car slowing down a example of mechanical energy transferred
A
Friction acts between the cars breaks and wheels. Energy is transferred by the wheels of kinetic energy stored to the thermal every store of the surrounding
