What factors does air resistance depend on?
The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air. Air densities vary with altitude, temperature and humidity.
Is air resistance a non contact force?
Contact forces are those that result from the interaction of objects in contact with each other. These include things like friction, air resistance, applied force, tension force, and spring force. Non-contact forces are those that result from the interaction of objects not in contact with each other.
What are the factors that affect the amount of air resistance?
The actual amount of air resistance encountered by the object is dependent upon a variety of factors. To keep the topic simple, it can be said that the two most common factors that have a direct effect upon the amount of air resistance are the speed of the object and the cross-sectional area of the object.
Why is the air resistance of a heavy object insignificant?
Air resistance is insignificant for heavy objects precisely because it doesn’t depend on the mass. This is because a force is just an interaction that tries to change the momentum of an object, and the momentum depends on the mass; the larger the mass, the larger the momentum, and the more force you need to change it.
What is the effect of air resistance on projectile motion?
Most of the time, its effect is so little that its different is only less than 0.1\%. We don’t, but elementary textbooks do, Without air resistance the differential equation for projectile motion can be solved analytically. With realistic air resistance, it can only be solved numerically. How does air resistance affect the motion of a projectile?
What is the amount of air resistance an object experiences?
Investigate! The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air. Air densities vary with altitude, temperature and humidity. Nonetheless, 1.29 kg/m3 is a very reasonable value.
