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)
Gravitational potention energy? The
Ep=mgh, the newton's 2nd law, the gravity,is pulling the car down,
thus resultant force= car puling torque - the pulling force
down
2) why does a coin and a feather fall at the same time in
vaccuum?
( they are different mass right?)
the freefall theory if i not
wrong
