This can be referred to as the "opening force" of the canopy.
When the parachute opens gravity stays the same. The force that changes is the air resistance. Air resistance is usually calculated using the drag calculation.
air resistance , maybe!
A skydiver - he uses a parachute that slows him down as a result of air resistance acting on the surface of the parachute
When you are running on a road ,you are acted upon by frictional force of the road.Is there another force of friction acting on you ? name and explain
force due to gravity acts vertically down wards and force of push acting upward
a small parachute, is a small parachute, ther is no technical name for it. :) a small parachute is called a drogue
It is your weight, which manifests as a downward force exerted by your body, although it is also an acceleration to a greater force if you fall.
I'd call it the resultant, but "net force" is a good name too.
