Temperature is another condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly.
Explanation:
Hence, the measure of how high or low a sound is called the pitch.
Loudness of sound is measured in decibels (dB). This is actually a measure of intensity, which relates to how much energy the pressure wave has. Decibels are a relative measurement. ... (To convert from a decibel reading in air to a decibel reading in water, you should add 61.5dB.)
How is Sound Produced? Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2.
Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. ... When the pendulum swings back down, the potential energy is converted back into kinetic energy. At all times, the sum of potential and kinetic energy is constant.
Joules is considered as the SI unit because - measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N acting over a distance of one meter (m).
KE = ½mv²
KE = ½(40 kg)(3 m/s)²
KE = 180 J
