Average velocity is average speed in a direction or a vector. G is the free fall acceleration expressed in ms² or fts². Speed velocity and acceleration Average speed is distance divided by time.
D v x t where v is the velocity average speed t is the time and d is distance so you can read it as Distance Speed x Time.
The magnitude of an objects acceleration as described by Newtons Second Law is the combined effect. Some other things to keep in mind when using the acceleration equation. The other formula if you have the initial and final speed add the two together and divide by 2. V2-u22as v2 u2 2as.
