What are the directons in which the forces are acting when a parachutist when he is falling?
When a parachutist is falling, the forces acting on them are gravity pulling them downward and air resistance pushing against their fall. Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.
If a 500 N parachutist opens their chute giving an air resistance force of 900 N what is the net force?
If the falling parachutist has a downward force of 500 N, and the air resistance force is 900 N (negative), then the net force is:500 N - 900 N = -400 N So, the parachutist gets a net upward force, causing him to decelerate while continuing to move downward, due to gravity.
When A parachutist reaches it terminal speed?
When a parachutist reaches terminal speed, the force of air resistance pushing up on the parachutist equals the force of gravity pulling the parachutist downward. At this point, the net force on the parachutist is zero, resulting in a constant velocity.
A 500-N parachutist opens his chute and experiences an air resistance force of 800 N The net force on the parachutist is?
The net force on the parachutist is 300 N (800 N - 500 N = 300 N) in the opposite direction of the parachutist's downward motion. This net force contributes to the deceleration of the parachutist as they descend.
Would a parachutist be considered a free falling object and why?
The falling of a parachutist without his parachute deployed will be quite fast. We can slow his decsent by putting a drag on the free fall with a parachute. The fall is no longer free of drag (friction).
When a parachutist is moving with a constant speed what happens?
There are two possibilities. One is that he is falling at a constant (positive) speed. In this case, the downward force of gravity is exactly offset by the upward force of drag or air resistance. The parachutist is said to have reached terminal velocity. The second possibility is that he is moving downwards at a constant speed of zero. He has hit the ground! The parachutist may be said to have reached a terminal situation!
What is the force that pulls falling objects to earth?
Gravitational force
What force keeps spacecrafts from falling to the earth?
Gravity.
Why the earth exerts a force on falling bodies?
gravity
Does a falling object that is falling towards the earth exert a smaller force on the earth than the force exerted by the earth onto the object?
No, according to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, the force exerted by the object on the Earth is equal in magnitude to the force exerted by the Earth on the object.
Which force is most responsible for raindrops falling to earth?
gravityThe gravitational force of attraction.
What is the force that pulls the freely falling body towards the earth is called?
Gravitational Force
