New cards

when it is from rest…

v1=0 m/s

2
New cards

when it comes to a stop…

v1= 0 m/s

3
New cards

Acceleration on earth

  • 9.8 m/s²

4
New cards

if two objects have the same air resistane

they will have same negative acceleration (fall at the same time)

5
New cards

if two objects have different air resistance

different negatime acceleration (one will fall first)

6
New cards

factors contribuuting air resistance

shape of object

  • circle have less air resistance

surface area of object

  • smaller = less air resistance

orienatation of object

  • direction

7
New cards

what do we assume when we have “falling objects” problemw

no air resistance

8
New cards

apex

maximum/point of accelleration is 0 and velocity is NOT 0
