Which encounters the greater force of air resistance a falling elephant or a falling feather?
A falling elephant encounters a greater force of air resistance than a falling feather does. The force of air resistance can't be greater than the weight of the falling object. When the force of air resistance is equal to the weight of the falling object, the object stops accelerating, its falling speed becomes constant, and the force of air resistance doesn't get any bigger. So the force of air resistance against a falling feather can't be greater than the weight of the feather. But the force of air resistance against a falling elephant can be, and undoubtedly is, greater than the weight of a feather.
When a 25 n falling object encounters 15 n of air resistance the net force on it is.?
25-15= 10n
When an object falls through the air and encounters air resistance it's overall speed will be what?
When an object falls through the air and encounters air resistance, its overall speed will decrease compared to if it were falling in a vacuum. Air resistance creates a force in the opposite direction of motion which slows down the object.
What is the net force acting on a 12-N falling object when it encounters 12-N of air resistance?
The net force would be zero, which means the falling object would no longer be accelerating, and would be falling at terminal velocity, which is a constant velocity. Weight is a downward (negative) force and air resistance is an upward (positive) force. Fnet = weight + air resistance = -12N + 12N = 0N
What force opposes the downward motion of falling object?
The force that opposes the downward motion of a falling object is air resistance, also known as drag force. This force acts in the opposite direction to the motion of the object and increases with the speed of the object.
What is the direction of air resistance on a falling object ?
Just like any other source of friction, air resistance effectively results in a force opposite to the object's motion. If the object is falling, then the force is upward.
When the only force acting on a falling object is air resistance?
The word "falling" implies there is a gravitational force also. As the object gains speed, the air resistance ("drag") increases, until it equals the gravitational force. After that there is no net (resultant) force, so the object goes at constant speed.
A 20 N falling object encounters 4 N of air pressure what is the magnitude of the net force on the object?
The net force on the falling object is the difference between the gravitational force pulling it down (20 N) and the air resistance force pushing against it (4 N). Therefore, the magnitude of the net force on the object is 16 N.
When the only force acting on force a falling object is air resistance the object is said to be in free fall?
True (:
The force air exerts on a falling object is known as?
air resistance
The two force acting on falling object are gravity and?
air resistance.
What 2 principal factors affect the force of air resistance on a falling object?
The shape of the object and the density of the gas that the object is falling through.
