Happy Saturday friends Worldwide from Dr. TJ Gunn in Houston USA Velocity is a measure of how quickly an object moves. So, the velocity is the change in the position of an object, divided by the time. Velocity has a magnitude (a value) and a direction. The unit for velocity is meters per second (m/s). […]

## Frequency Formula

Happy Saturday friends Worldwide from Dr. TJ Gunn in Houston USA Frequency is the number of cycles in a unit of time. The “cycles” can be movements of anything with periodic motion, like a spring, a pendulum, something spinning, or a wave. Frequency is equal to 1 divided by the period, which is the time […]

## Force Formula

TGIF, Friends Worldwide from Dr. TJ Gunn in Houston Texas USA…… Force is the mass of an object, multiplied by its acceleration. The unit of force is . This is called a Newton, with the symbol N. Force has a magnitude and a direction. force = mass x acceleration F = ma F = force m […]

## Acceleration Formula

TGIF, friends Worldwide from Dr. TJ Gunn in Houston Texas, USA…… Acceleration is a measure of how quickly the velocity of an object changes. So, the acceleration is the change in the velocity, divided by the time. Acceleration has a magnitude (a value) and a direction. The direction of the acceleration does not have to […]
