^{What is the definition of dissipated energy?}

• Energy that is released into the atmosphere that will never return again
• Heat from the sun that is released into energy for our world
• Energy that is dissipated as sound energy
• Energy that is released into the surrounding area, usually as thermal

When person is biking on the road, they suddenly come to a stop to let a car pass. Some of this energy _______.

• Dissapears
• Dissipates
• Transforms to light
• Does not change

When some energy dissipates, what happens to the the energy?

• It increases
• The energy is released to the atmosphere and never found again
• The energy decreases
• The energy stays the same

A baseball player hits a pitch, and it goes flying before a player catches it in the air. The players hand goes back after the the ball hits their glove due to the velocity of the hit. What happened to the energy?

• Some of the energy is transferred to the glove
• The energy does not go to the glove
• The energy is stopped by the glove and none is left

_{I throw a softball in a room and it bounces off the walls, what happens to the energy?}

• It stays constant in the ball and keeps bouncing
• It immediately stops bouncing due to all the energy going to the wall.
• The energy slows down
• The energy dissipates until the ball is not gaining energy and it slows to a stop

_{What is the true about the waves?}

•  The top wave has a longer wavelength, lower frequency, and slightly bigger amplitude
• The bottom wave has a higher frequency, a longer wavelength, and  lower amplitude
• The bottom wave has smaller frequency, shorter wavelength, and higher amplitude
• The top wave has a larger wavelength, lower frequency, and a smaller amplitude

What happens to the amount of energy with wavelength and amplitude?

• The energy increases with smaller wavelength and decrease with larger amplitude
• The energy increases with smaller wavelength and decreases with smaller amplitude
• The energy stays the same
• The energy increases with larger wavelength and decreases with larger amplitude
