Types of Energy
What is the difference between potential and kinetic energy?
Potential energy is stored energy. Kinetic energy is an object that is in motion.
Does conduction require direct or indirect contact?
Direct contact.
The slinky produced a wavelength of 4 m as the vibration occurred at 5 Hz. Solve for the wave-speed.
20 m/s
What is the difference between a series and a parallel circuit?
A series circuit uses one path for energy and a parallel uses multiple paths for energy.
True or false, energy is the ability to do work or cause change.
True.
What is an example of radiation?
Microwave, hand over a fire, the pan hovering over a burner.
A wave traveling in water has a frequency of 500 Hz and a wavelength of 3 m. What is the speed of the wave?
1500 m/s
What would happen to a light bulb if the switch is open?
The light bulb will not turn on and energy is not flowing through the circuit.
What forms of energy make-up mechanical energy?
Potential and kinetic energy.
Which state of matter is used during convection?
Liquid and gas.
The wave hit the beach traveling 2 m/s with a frequency of 30 Hz. What is the wavelength?
.07 m
What does a resistor do in a circuit?
A resistor does not let the energy flow freely. Instead, it has energy flowing equally.
What type of energy is stored in food?
Chemical energy.
Touching the handle of a pot is an example of which type of thermal energy?
Conduction.
In air at atmospheric pressure, an ultrasonic wave has a wavelength of 1.9 cm and a frequency of 20 kHz. Solve for the missing component.
38 m/s
Draw a series circuit using all of the components on the board.
The answer will vary...
What is an example of nuclear energy?
The sun.
Warm air rises because it is less dense than cold air.
A piano emits a note that travels 340 m/s and has a wavelength of 4 m. Solve for the missing component.
85 Hz
Draw a parallel circuit using all of the components on the board.
The answer will vary...
