Question

difference between negative acceleration and positive acceleration​

Answer 1

Answer:

-ve acceleration or retardation: { when a body is thrown upwards }

v = 0

u has some value and is never equal to 0 in this case. So u>v .

a = v-u / t

  = 0-u/t

  = - ( answer) m/s^2

+ve acceleration : { when a body is thrown downwards }

u= 0

v has some value and is never equal to 0 in this case. So v > u.

a = v-u / t

  = + (answer) m/s^2

I would appreciate it, if you mark me Brainliest. I hope your doubt is now cleared.

Cheers!
