What two principles factors affect the force of air resistance on a falling object?
What two principal factors affect the force of air resistance on a falling object? The force depends mostly on frontal area and speed. What is the acceleration of a falling object that has reached its terminal velocity? The acceleration is 0.
What two principal factors affect the force of air resistance on a falling object what two principal factors affect the force of air resistance on a falling object?
When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. Air resistance depends on two important factors – the speed of the object and its surface area.
How does air resistance affect a falling object?
With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. How much it slows the object down depends on the surface area of the object and its speed.
What three factors affect the amount of air resistance on an object?
The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air.
What are the forces acting on an object falling through air?
An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object, and the second force is the aerodynamic drag of the object.
What is the net force that acts on a 10-n falling object?
What is the net force that acts on a 10-N falling object when it encounters 4 N of air resistance? When it encounters10 N of air resistance? The net forces are 6 N and 0 N, respectively. What two principal factors affect the force of air resistance on a falling object?
Is the force acting on an object in the atmosphere constant?
But for most practical problems in the atmosphere, we can assume this factor is constant. If the object were falling in a vacuum, this would be the only force acting on the object. But in the atmosphere, the motion of a falling object is opposed by the aerodynamic drag.
What is the weight of an object falling through the atmosphere?
An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object, and the second force is the aerodynamic drag of the object. The weight equation defines the weight W to be equal to the mass m of the object times the gravitational acceleration g :
