Is forces on the parachute upthrust and down force?
The main forces acting on a parachute are drag force (opposes the motion) and the force of gravity (pulls the parachute downwards). Upthrust, also known as lift force, can also be present when the parachute is deployed properly and creates a lifting force that helps slow down the descent. Overall, the forces involved include drag, gravity, and lift.
What are the four forces that act on planes?
The four forces that act on a plane in flight are lift, weight (gravity), thrust, and drag. Lift is generated by the wings to overcome gravity (weight), while thrust from the engines propels the plane forward to overcome drag, which is the resistance of the air against the forward motion of the aircraft.
What two forces act on a parachute when it falla can you draw a diagram?
The two forces acting on a parachute when it falls are gravity, pulling it downward, and air resistance (drag), pushing against its motion. As the parachute opens, air resistance becomes higher, counteracting gravity and slowing down its descent. Unfortunately, I can't draw a diagram as I'm a text-based assistant, but you can easily search for parachute force diagrams online.
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
What is the abbreviation for parachute?
The abbreviation for parachute is "PCHT."
