Hello i have only two qns after my revision so far. I asked most
of my friends but they dont know.
1) A car is driving on a horizontal flat road with
a constant speed.
As the car moves uphills, the speed starts to slow
down meaning the forces acting against the car increases(following
me?)
What force acting against the car actually increased?(material of
the surface is the same)
2) why does a coin and a feather fall at the same
time in vaccuum?
( they are different mass right?)
