Energy Storage
This energy storage mode increases when you stretch and object (like a rubber band)
What is Potential Energy stored Elastically?
A person jumps from a height of 10 m into a pool below. At the top of the jump this person is storing ______
What is gravitational potential energy?
A transfer of energy with no transfer of mass or matter
What is a wave?
These two things do NOT affect the speed of a wave
What are frequency and amplitude?
Smartphones, laptop computers, and gaming consoles are all examples of devices that use this storage of information
What is digital storage?
These are the two ways you can increase the amount of kinetic energy stored in an object.
What are changing its mass and speed (how fast its moving)?
The m in GPE = mgh stands for this.
The g in GPE = mgh stands for this.
The h in GPE = mgh stands for this.
What is mass?
What is acceleration due to gravity?
What is height?
This is the part of the wave that determines the loudness of sound and the brightness of light.
What is Amplitude?
This equation helps you solve for the speed of a wave.
What is v = fλ
This signal is a continuous wave. It is easily susceptible to noise.
What is an analog signal?
These are all 4 of the different forms potential energy can be stored.
What are gravitationally? Chemically? Elastically? And electrically?
The number that you substitute in for g (acceleration due to gravity) in GPE = mgh is this.
What is 10 m/s2 ?
This is the part of the wave that determines the pitch of sound and the color of visible light.
What is Frequency?
A wave has a wavelength of 3 m and a frequency of 9 Hz. This is the speed of the wave.
What is 27m/s?
This EM wave has the lowest frequency on the EM Spectrum
What are Radio Waves?
"Energy cannot be created or destroyed, it can only change its forms" is the definition of this.
What is conservation of energy?
This is the energy stored in a 60.0-kg person when they jump onto the floor from a height of 3.00 m.
What is 1764 J?
The phenomenon that occurs when objects begin to vibrate (oscillate) when the frequency of music matches the natural frequency of the object.
What is Resonance?
A wave has a speed of 30 m/s and a frequency of 6 Hz. Calculate its wavelength.
What is 5 m?
This EM wave is used to sterilize medical equipment and treat cancer by targeting and killing cancer cells.
What are Gamma Rays?
A ball rolls to a stop. The initial and final energy storage modes for the ball are this and that.
What are kinetic energy stored in movement and dissipated energy stored thermally?
This is the kinetic energy of a 625-kg roller coaster car that is moving with a speed of 18.3 m/s.
What is 104,653 J?
This type of wave has two key elements, that when produced by an instruments create a pattern that has no amplitude and doubled amplitude
What are standing waves, nodes (no amplitude), and antinodes (max amplitude)?
Frequency is 200 Hz. This is the period.
What is 0.005 seconds?
This is known as the threshold, above which electromagnetic radiation is considered dangerous to humans because it can damage the DNA in our cells.
What is ionizing radiation?
