A faster-moving object will have increased air resistance because more molecules of air will be encountered over the same time frame. The same holds true if an object that encounters denser air: there is more air resistance, therefore more lift as well as more drag.

What three factor affect the amount of air resistance on an object?

Speed, shape and frontal cross-section.


When air resistance is a factor affectin the ball will return to original with same less or more ke?

When air resistance is a factor, the ball will return to its original point with less kinetic energy due to the work done against the resistance of the air. The air resistance converts some of the ball's kinetic energy into thermal energy, causing a reduction in the ball's speed.


Does air density determine terminal speed?

Yes, air density can affect terminal speed. In denser air, there is more resistance, which can slow down an object more quickly, leading to a lower terminal speed. Conversely, in less dense air, there is less resistance, allowing an object to reach a higher terminal speed.


Do the velocity of falling objects does not change?

If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.


What are the factors that effect air resistance?

The factors that affect air resistance include the speed of the object (higher speed leads to greater air resistance), the surface area of the object (larger surface area experiences more air resistance), the shape of the object (streamlined shapes experience less air resistance), and the air density (higher air density increases resistance).


How does air resistance change speed?

Air resistance acts in the opposite direction of an object's motion to reduce its speed. The force of air resistance or drag is given by the following formula:FD = 1/2 A CD ρ v2whereA is the projected area of the objectCD is the drag coefficientρ is the air densityv2 is the relative velocity of the air


When an object fall through the air and encounters air resistance its overall speed will be than if it had not encountered air resistance?

Slower. Air resistance acts in the opposite direction to the motion of the object, reducing its speed as it falls.


How does the force of air resistance depends on an object's speed?

In general the resistance increases by the 4th power of the speed.


When air resistance is not negigble how does return speed compare with the initial speed?

When air resistance is not negligible, the return speed of an object will be slower than the initial speed because air resistance acts in the opposite direction of the object's motion, slowing it down. This results in a decrease in the object's speed over time.


Why parachutists do not fall with constant accelerating motion?

Due to air resistance as the resistance is directly proportional to the speed but at certain speed called transitional speed or critical speed the resistance become directly proportional to square the speed so the resistance increase decreasing the falling speed.


What is air resistance and what are the two factors that air resistance depends on?

Air resistance is the force that opposes the motion of an object through the air. It depends on the speed of the object and its surface area exposed to the air.


How does are resistance effect speed?

Resistance can decrease speed by slowing down the movement of an object. In the case of air resistance, for example, the force of air pushing against an object moving through it can reduce speed. Increased resistance requires more energy to overcome, which can lead to a slower speed.
