How does air resistance affect the trajectory of a projectile?

As a projectile moves through the air it is slowed down by air resistance. Air resistance will decrease the horizontal component of a projectile. The effect of air resistance is very small, but needs to be considered if you want to increase the horizontal component of a projectile.

How do you calculate projectile motion with air resistance?

Mathematically, the resistive force represented by the vector F can be written as F=-f(v) u, where u=V/|V| is the unit vector along the direction of the velocity V. The minus sign guarantees that the air resistance acting on the projectile is always opposite to the direction of its velocity.

Does projectile motion have air resistance?

Suppose, further, that, in addition to the force of gravity, the projectile is subject to an air resistance force which acts in the opposite direction to its instantaneous direction of motion, and whose magnitude is directly proportional to its instantaneous speed. …

Does projectile motion ignore air resistance?

A projectile is fired into the air, and it follows the parabolic path shown in the drawing. There is no air resistance. At any instant, the projectile has a velocity v and an acceleration a.

What will happen to the trajectory of a projectile when we take air resistance into consideration no longer in free fall )?

What will happen to the trajectory of a projectile when we take air resistance into consideration [no longer in free fall]? The horizontal component is no longer constant. That means that the path will fall shorter than if there was no air resistance.

How does air resistance affects the maximum height of a projectile?

Answer: Objects moving through air are slowed down due to air resistance, sometimes called drag. The maximum height, the range and the velocity of the projectile are all reduced.

What is trajectory in projectile motion?

Projectile motion is a form of motion where an object moves in a parabolic path. The path followed by the object is called its trajectory. The angle at which the object is launched dictates the range, height, and time of flight the object will experience while in projectile motion.

What is the path followed by the projectile?

The path followed by a projectile is called its trajectory. If we negligible air resistance, projectiles follows a curved trajectory or curved path that is a parabola.

Why do we ignore air resistance in projectile motion?

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 path taken by a projectile?

The path followed by a projectile is called a trajectory.

How is air resistance related to projectile motion?

In our study of projectile motion, we assumed that air-resistance effects are negli-gibly small. But in fact air resistance (often called air drag,or simply drag) has amajor effect on the motion of many objects, including tennis balls, bicycle riders,and airplanes. In Section 5.3 we considered how a fluid resistance force affected

What causes a projectile to move out of the plane?

Let the initial velocity of the projectile lie in the – plane. Note that, since neither gravity nor the drag force cause the projectile to move out of the – plane, we can effectively ignore the coordinate in this problem. The equation of motion of our projectile is written

Where does the initial velocity of a projectile lie?

Let us adopt a Cartesian coordinate system whose origin coincides with the launch point, and whose -axis points vertically upward. Let the initial velocity of the projectile lie in the – plane.

How is the force of air resistance written?
