Acceleration; what is it?
if you have a body,mass or material that at apoint of time is travelling at a speed and at another point in time is travelling at a faster speed then it has accelerated. Note; "speed is also called velocity"
We firstly have to determine what speed is. Speed is how much distance has been travel in a pre set time, for example 5m/s, this means in one second that the mass have travelled 5 meters (Note, speed can be shown in many ways, "miles/hr, ft/sec")
Now that we understand speed, we can look acceleration.
If we have a starting speed for example 10m/s we then measure one second later and the new speed is 11m/s, we can see that the actual speed has changed by 1m/s.
so how do we write this
change in speed= 1m/s
how long did it take to change this speed= 1 second
Therfore is 1meter per second per second = acceleration is 1m/s/s.
Hopefully this shows a method, with useful information to aid understanding, the gramma may be poor, but thats no my fortie!
