Acceleration is strictly defined as the second derivative with respect to time of position.
That is all.

acceleration results from the ratio (distance/seconds^2)
that means there is a relation of proportion but not a direct inverse.

The equation E = MC squared means that the energy is equal to the mass of an object multiplied by the square of the speed of light - thats a lot of energy! As you move thru space the energy required to increase your speed also increases and as it approaches the speed of light it increases to infinity. So you can go a long time just increasing your speed and it requires just a little more energy, but as you begin to approach near light speed all of a sudden the energy required to increase just a little becomes astronomical.

velocity is the rate at which distance changes per unit of time.
That is, velocity = (change in distance) / (time for change)
Acceleration is the rate at which velocity changes per unit of time.
That is, acceleration = (change in velocity) / (time for change)
For example, if a car goes from 10 km/hr to 20 km/hr in 1 minute, then ...
acceleration = (10 km/hr) / (1 minute)
acceleration = (10 km / 60 minute / 1 minute)
acceleration = (10/60) km / (minute x minute)
acceleration = (0.1667) km / (minute ^2)
acceleration = 166.7 m / (60 second x 60 second)
acceleration = 0.046157 m / (second^2)
