What is the unit of work in the SI system?
joule
pascal
watt
newton
Which of the following is a form of energy?
Thermal energy
Nuclear energy
Kinetic energy
Chemical energy
What is the formula for kinetic energy?
KE = 2mv
KE = mv^2
KE = 1/2 mv^2
KE = 1/2 m^2v
What is the principle of conservation of energy?
Energy can be created from nothing.
Energy is always lost in transformations.
Energy can be destroyed but not created.
Energy cannot be created or destroyed, only transformed.
What type of wave is a sound wave?
Surface wave
Longitudinal wave
Electromagnetic wave
Transverse wave
What is the speed of sound in air at room temperature?
250 meters per second
400 meters per second
343 meters per second
300 meters per second
What is the relationship between frequency and wavelength?
Frequency and wavelength are directly related.
Wavelength increases with increasing frequency.
Frequency has no effect on wavelength.
Frequency and wavelength are inversely related.
What is the formula for power in terms of work and time?
Power = Work / Time
Power = Work + Time
Power = Work - Time
Power = Time / Work
What is the difference between potential energy and kinetic energy?
Potential energy is stored energy based on position; kinetic energy is energy of motion.
Potential energy is related to temperature; kinetic energy is related to pressure.
Potential energy is always greater than kinetic energy; kinetic energy can never be negative.
Potential energy is the energy of motion; kinetic energy is stored energy based on position.
What is the Doppler effect?
The Doppler effect is the increase in amplitude of a wave due to the motion of the observer.
The Doppler effect refers to the change in color of light due to the speed of the source.
The Doppler effect is the phenomenon where sound waves become louder as they approach the observer.
The Doppler effect is the change in frequency or wavelength of a wave due to the relative motion of the source and the observer.
