Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.

Mass divided by volume
The equation used to calculate the distance something travels is given below . we know, speed = distance /time . distance = speed X time in meters /km /or any other unit of length.
Thanks to Isaac Newton's Second Law of Motion, one can determine the mass of an object if he or she knows both the force acting upon the object and the acceleration of the object. Newton's equation is as follows: F = ma; where "F" is the force acting upon the object, "m" is the mass of the object. and "a" is the acceleration of the object. Solving for "m", the equation can be rewritten as: m = F/m. Substitute force for "F", and acceleration for "a", and you can solve for the mass of the object.
