How will the upward force of air resistance compare to the downwward pull of gravity?
Assuming that you're referring to an object that is accelerating towards a massive body by means of gravitational attraction...
When the force of frictional air resistance equals the opposing force of gravity, the net force on the object equals zero, and acceleration will cease. It is called terminal velocity, and the object will remain at this velocity until some new event happens.
What else can I help you with?
If a ball is dropped from the top of a building the upward force of air resistance becomes equal to the downward pull of gravity what will happen when the two forces become equal in magnitude?
When the upward force of air resistance becomes equal to the downward force of gravity, the ball will reach its terminal velocity and stop accelerating. The net force acting on the ball will be zero, and it will continue to fall at a constant speed.
When an object is falling at terminal velocity what is the net force acting on the object?
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
Why does a firework rocket fall back to earth?
After a firework rocket is launched, it reaches a certain height where the fuel is expended and the upward thrust stops. At this point, gravity takes over and begins to pull the rocket back down to Earth. Additionally, air resistance and drag force also play a role in slowing down the rocket's upward motion and causing it to fall back.
What forces have to be balanced for terminal velocity to be reached by an object?
For an object in freefall, terminal velocity is reached when the drag force becomes equal and opposite to the force of gravity. This creates a net force of 0, resulting in no further acceleration.
If you were to weigh yourself in an elevator that is in free fall would you weigh more?
Free fall means the upward acceleration of air resistance cancels out the downward acceleration of gravity, leaving only your mass. If you're confused about the difference between mass and weight: Weight = (mass) * (gravity (9.8 m/s^2)) Mass = weight/gravity
An object is projected straight upward. Neglecting air resistance it .?
It will rise until the force of gravity on it equals the initial force used to project it upward. At that point, it will momentarily stop before falling back down due to gravity.
How many forces act on a body when a body is thrown upward?
Once it is in the air, the main forces are gravity, and air resistance.
What forces act on a falling object?
The main forces acting on a falling object are gravity and air resistance. Gravity pulls the object downward toward the ground, while air resistance, or drag, slows down its descent by pushing upward against it. The net force of gravity minus air resistance determines the object's overall acceleration as it falls.
When a body is thrown upwardhow many forces act on it?
when abody is thrown upward,how many forces act on it?what is the role of the force with which the body has been thrown upward? After a body is thrown upwards, you have gravity pulling it down and friction slowing it.
What are the 2 forces acting on a parachutist?
Gravity (downwards), and air resistance (upwards).
If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?
If air resistance can be neglected, the acceleration of a ball tossed straight upward is the same as when it is dropped - both experience a gravitational acceleration of 9.81 m/s^2 downward. The initial velocity of the tossed ball would cause it to momentarily counteract the acceleration and then eventually slow down and reverse direction due to gravity.
What is the upward force that acts on an object that is falling through the air?
The upward force acting on an object falling through the air is called air resistance or drag. This force opposes the motion of the object and increases as the object's speed increases. It ultimately results in a terminal velocity when the upward force equals the downward force of gravity.
What is an upward force?
It is a force which acts in the upward direction.
What is the upward force that works against gravity?
Any upward force works against gravity,since they act in opposite directions.
What is reached when the downward pull of gravity is equal to the upward push of air resistance?
The object would stop falling. This is what allows things to float, and what keeps planes in the air.
What do you get when you subtract the forces of air resistance from the forces of gravity?
Terminal Velocity
What happens to a falling object when the of air resistance the force of gravity?
Falling objects increase their speed as they fall, because their weight (the force of gravity) pulls them to Earth. ... Objects fall faster until they reach their terminal speed, which is reached when the upward (air resistance) and downward (weight)forcesare equal.
