## sami2012 3 years ago What is the formula to calculate acceleration

1. j814wong

a = Δv/Δt = (vfinal - vinitial) / (tfinal - tinitial)

2. sami2012

is there anything simple enough for 7th grade math

3. sami2012

hellow @j814wong

4. j814wong

I'm afraid that's the most basic one. It's just the difference in start and ending velocities divided by the time between the times at which the start and ending velocities are. For example, let's say that the initial velocity is 0 m/s at 0 seconds and the final velocity is 5 m/s 1 second latter. The acceleration would be calculated as (5 m/s - 0m/s)/(1 s - 0 s)

hi

6. sami2012

let me search it up on google

7. j814wong

For 7th grade math, that's probably the only other formula you'll ever have to use for acceleration unless another one is given for more advance questions.

8. j814wong

Sure. Oh and one other thing, the triangle simple is the delta symbol which means "change in" or "difference" between values.

@j814wong so what would be the answer to : what is the acceleration of an object that starts stopped and after 5 seconds is going 25m/s

11. j814wong

a = Δv/Δt = (vfinal - vinitial) / (tfinal - tinitial) = (25 m/s - 0 m/s)/(5 s - 0s) Starting stop means a 0 m/s at the initial time or 0s. You are also given the final times for the calculation of 25 m/s after 5 seconds. Just plug in.
