What is a equation use to calculate speed?

Answer 1

There are several equations that involve speed; the basic equation, that defines speed, is:

speed = distance / time

Which is often written as:

distance = speed x time

This assumes constant speed. For variable speed, the limit should be taken, resulting in:

dv = ds/dt

where v is the velocity, s is the position, and t is the time.

Answer 2

Speed=Distance/Time So if you divide the distance in km by the time in hours you get speed in km/h or if you divide the distance in m by the time in seconds you get speed in m/s etc. Speed is a scalar quantity, meaning that it doesn't have a direction. 50 miles per hour could mean 50 miles per hour north, south, east or west. Velocity is speed plus a specifed direction, and it is much more useful than speed when it comes to physics. Velocity is a vector quantity, because it has magnitude and direction, so we can use it much more often than just speed.

Answer 3

Distance ÷ Time (distance divided by time)

Answer 4

final speed = Vf, but there is no equation for it.

Answer 5

The formula states that speed is equal to the distance divided by the time. If you are using SI units, then the answer for speed is given in meters per second.

Answer 6

Depends what other things you know, like initial velocity, acceleration, time,

force, mass, distance, etc.

Answer 7

x6^6^6-2+x0*x+Vo

Answer 8

distance divided by time

Answer 9

Distance over Time or D/T
