Explain the transformation that takes place when you play an instrument (3 step)
What is chemical (stored in food) to mechanical (movement ) to sound (sound produced from instrument)
Energy can not be created or distroyed.
What is law or conservation or energy?
An ice cube melts when it is in your hand?
What is Conduction
Explain the transformation that takes place when you turn on a flashlight. From the battery to the light. 4 steps
What is Chemical (of the battery) to electrical (flow of electrons) to radiant (of the light) to thermal ( the heat produced by the light)
Energy transformation of a microwave? (3)
What is electrical to electromagnetic to thermal?
Sunlight
What is Radiation?
This is an example of electrical energy being changed to radiant energy.
What is a lamp?
A Heater warming a room.
What is Convection?
Explain the transformation of energy that occurs as running water turns a turbine that powers the lights. 4 steps
What is Mechanical to Electrical to Radiant/Light to Thermal
Solar panels are on your house, it is used to power all appliances. You use the oven to bake cookies. What energy transformations occur that enable him to make cookies?
What is light/radiant energy to electrical energy to heat/thermal energy?
a substance which does not readily allow the passage of heat.
What is an insulator?
A ball is dropped from 3 different heights. Each time the kinetic energy of the ball for when it hits the ground is calculated. The data shows the higher the ball started the more kinetic energy it had. If the height of the drop continued to increase what would happen to the kinetic energy?
What is the kinetic energy would also continue to increase.
When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. Explain how the law of conservation of energy is obeyed.
What is During each bounce, some of the kinetic energy of the ball in transferred into thermal energy. As a result, energy is not created or destroyed, but only changes form so that the law of conservation of energy is obeyed.
