How to determine acceleration
How do you determine acceleration? And how might I explain this at a
6th grade level?
Acceleration is the rate at which velocity of an object
changes. It is determined by measuring velocity of the object
in question at two instants of time, , separated by a small
interval of time. Acceleration is just the difference of these
velocities divided by the interval of time between the two observations.
This is true only if the interval separating two observations
is very small.
