when it is from rest…
v1=0 m/s
when it comes to a stop…
v1= 0 m/s
Acceleration on earth
9.8 m/s²
if two objects have the same air resistane
they will have same negative acceleration (fall at the same time)
if two objects have different air resistance
different negatime acceleration (one will fall first)
factors contribuuting air resistance
shape of object
circle have less air resistance
surface area of object
smaller = less air resistance
orienatation of object
direction
what do we assume when we have “falling objects” problemw
no air resistance
apex
maximum/point of accelleration is 0 and velocity is NOT 0
