P1.2 Conservation Of Energy Flashcards
How can i experiment energy loss
Using a pendulum with graph paper or a ruler behind, raise the mass of the ball attached to a certain height you are recording. Then, drop it at watch its swing. A person must be facing directly in front of it and monitor where it swings
If i conducted an experiment with a pendulum would it swing forever
No as their is air resistance and friction
Has energy been lost in this experiment?
Transferred to a thermal store and dissipated to its surroundings
What is the conservation of energy
Energy cannot be created or destroyed only transferred
What is a closed system
A closed system is a system where energy can enter or leave, but matter cannot.
How does this experiment differ if its in a closed system
It would swing forever as there is no energy transfer
