Question

whats an example of acceleration?

Answer 1

A car that keeps on increasing its velocity.

Answer 2

accelaration is changing your velocity in time. For example You re walking some length in 5 minutes. But when you run that length you be more acceraleted.

Answer 3

Remember that g = a*t, plug in numbers.
We know the a = 9.8, and t varies. Dropping a rock from the top of a building. Assuming no air resistance it will increase at
\[9.8m/s^2\]

That is \[g = 9.8m/s^2\]
