Q

formula ofaverage acceleration

A

=change in velocity/change in time

18
Q

what does the slope of a position-timegraph tells us?

And what does its absolute value tell us?

A

slope = average velocity

abs = average speed

19
Q

what does the slope of velocity-timegraph tell us

A

acceleration

20
Q

What soes a **negative acceleration ** tells us about an object

A

velocty=decreases
object=thrown up
speed=decreases

21
Q

What soes a **positive acceleration ** tells us about an object

A

velocity=increases
object=falls down
speed=increases

22
Q

what are the three acceleration formulas?

A
  • Vf=Vi+axTf
  • Df=Di+VixTf+1/2axTf^2
  • V^2f=V^2i+2ax(Df-Di)

contact:
friction
air resistance
tension
field:
gravity
magnetic
electric
