The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.

The slope of a velocity graph is the acceleration.

Multiplying the wave’s frequency by its wavelength, which is its physical length, yields the velocity of the wave. The relationship can be expressed as velocity equals frequency times wavelength.

What is wave velocity? It is the speed that the wave advances through a medium.

Waves and Energy: The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l * f).

Velocity. The distance travelled by a wave in one second is called velocity of the wave or speed of the wave. Its S.I. unit is metres per second (m/s). Velocity = Distance travelled/Time taken.

Primary Waves (or P-Waves) – These are compressional waves, also known as longitudinal waves and are the first seismic waves to arrive at a location on the Earth. This type of wave has the highest velocity for traveling through Earth materials.

The velocity of the wave, v, is a constant determined by the properties of the medium in which the wave is moving as we saw above. The velocity is a vector which gives the forward speed of the wave and the direction the wave is traveling.

Waves can be in the group and such groups are called wave packets, so the velocity with a wave packet travels is called group velocity. The velocity with which the phase of a wave travels is called phase velocity. The relation between group velocity and phase velocity are proportionate.

This equation shows how the three factors are related: Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

SI base units. kg⋅m2⋅s−3⋅A−2. The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Ohm.

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1).

But if a body does not move in a single straight line, then the speed and velocity of the body are not equal. So, in this case the magnitude of speed and velocity of the boy is not equal. This happened because boy does not move in a single straight line. He has changed the direction of motion after reaching the shop.

1. Calculate v = (v + u) / 2.
2. Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two.
3. The average velocity calculator solves for the average velocity using the same method as finding the average of any two numbers.
4. Given v and u, calculate v.
5. Given v and v calculate u.

Multiply the height by the object’s acceleration due to gravity. The acceleration due to gravity is 32.2 ft/s^2 for English units, or 9.8 m/s^2 for SI units. If you drop an object from 15 feet, for example, you would multiply 15 ft * 32.2 ft/s^2 to get 483 ft^2/s^2. Multiply the result by 2.
