There are several definitions. not just one.
Average velocity in a direction = Average displacement (distance) in that direction/time
Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time
Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time
Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0
Then there are others in which time is eliminated.
The formula for velocity is (v = d/t) or (velocity = distance/time).
Velocity is distance / time
velocity = frequency / wavelength, I believe.
Final velocity v = u + at
Since speed or velocity = distance/time ,its dimensional formula =L/T = [MoLT-1]
The formula for uniform velocity is: Velocity = Distance / Time.
The formula for velocity is (v = d/t) or (velocity = distance/time).
Velocity is distance / time
velocity is distance/time
Final velocity = (Initial velocity) + (time)(acceleration)
The formula for finding final velocity is: v = u + at, where: v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time taken.
v(t) = dsdt This should be the formula for instantaneous velocity.
velocity = frequency / wavelength, I believe.
Velocity=displacement(distance)/time.
The formula to calculate acceleration is: acceleration = (final velocity - initial velocity) / time.
Deceleration is the rate of decrease of velocity with respect to time. It is the negative of acceleration. The formula for deceleration is the same as that of acceleration, only that the acceleration is represented as negative. The formula is: - (deceleration) = (final velocity) - (initial velocity) time Therefore, (deceleration) = (initial velocity) - (final velocity) time
The formula for acceleration is: acceleration = (final velocity - initial velocity) / time. It is the rate of change of velocity with respect to time.
