What Is Air Resistance And How Does It Affect Motion?


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. Increasing the surface area of an object decreases its speed.



At which angle range of projectile is maximum?

45 degrees


How do you explain air resistance to children?

Air resistance is the frictional force air exerts against a moving object. As an object moves, air resistance slows it down. The faster the object's motion, the greater the air resistance exerted against it.


What is the importance of air resistance?

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 is the effect of air resistance on time of flight and horizontal range of projectile?

1 Answer. The effect of air resistance is to increase time of flight and decrease horizontal range.


When air resistance is taken into account while dealing with the motion of projectile?

In the presence of air resistance, the range, maximum height, speed at which the projectile strikes the ground will decrease whereas the angle at which the projectile strikes the ground will increase. Was this answer helpful?


What's an example of air resistance?

Translation: Air resistance is a force that is caused by air. The force acts in the opposite direction to an object moving through the air. A lorry with a flat front will experience high air resistance while a sports car with a streamlined shape will experience lower air resistance, allowing the car to go faster.


How does air resistance happen?

What Causes Air Resistance? Also known as 'drag,' air resistance is a force caused by air. The air particles hit the front of an object, causing it to slow down. The greater the surface area, the greater the number of air particles hit the object and the greater the overall resistance.


How do you account for air resistance?

Air resistance can be calculated by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared.


Why do we neglect air resistance in projectile motion?

As an object travels through the air, it encounters a frictional force that slows its motion called air resistance. Air resistance does significantly alter trajectory motion, but due to the difficulty in calculation, it is ignored in introductory physics.


What is air resistance and how does it affect motion?

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. Increasing the surface area of an object decreases its speed.


How do you use air resistance in a sentence?

The air resistance produced by the cables is therefore very slight, since only two lines are exposed. Only when it was up where air resistance was a very small fraction of ground-level drag would its own rockets fire. They recorded how air resistance caused it to deform and eventually break up.


When the air resistance is taken into account while dealing with the motion of the projectile to achieve maximum horizontal range the angle of projection should be?

Detailed Solution

θ = angle at which an object is thrown from the ground. Maximum Range: It is the longest distance covered by the object during projectile motion. When the angle of projection is 45°, the maximum range is obtained.


What is the role of air resistance?

By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down.


When no air resistance acts on a projectile what will be its horizontal?

In order to accelerate a resultant force is required (according to Newton's Second Law, →F=m→a ). In the absence of air resistance the only force acting on a projectile in flight is the weight of the object. Weight by definition acts vertically downwards, hence no horizontal component.


How do you identify spot errors?

Spotting errors are asked in verbal reasoning. You need to spot sentences and error which are grammatically incorrect. This error can be anything. From noun to pronoun to singular/plural to word usage they can be anything.


What is manual control?

Manual Controls are controls that are manually performed by individuals. They may be solely manual where no IT generated reports are used or they may be IT Dependent whereby an employee is using a system generated report to test the validity of a particular control.


How the sum of triangle is 180?

A triangle's angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle.


Does momentum increase after an explosion?

Scenarios that Increase the Kinetic Energy:

When there is a bomb explosion, the momentum and kinetic energy are zero before the explosion. Thus the total momentum must remain zero, but the kinetic energy clearly increases after the explosion.


What is the difference between luminous and Nonluminous flame?

A luminous flame is of yellow color whereas the non-luminous flame is of blue color. A luminous flame is formed on incomplete combustion of the fuel whereas the non-luminous flame is formed on complete combustion of the fuel. The non-luminous flame exhibit hot temperature as compared to the luminous flame.
