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.
What factors affect the trajectory of a projectile?
Factors affecting the flight path of a Projectile are:
- Gravity.
- Air Resistance.
- Speed of Release.
- Angle of Release.
- Height of Release.
- Spin.
How does air resistance affect 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.
Does air resistance affect horizontal or vertical velocity?
Air resistance would cause a horizontal acceleration, slowing the horizontal motion, but since we’re going to only consider cases where air resistance is negligible we can assume that the horizontal velocity is constant for a projectile.
Why is the trajectory of a projectile always a curved path?
Horizontal component of motion is completely independent of the vertical component of motion. Their combined effects produce the variety of curved paths that projectiles follows. We find that projectiles move equal horizontal distances in equal time intervals since no acceleration takes place horizontally.
What affects the air resistance?
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.
How does air resistance affect the vertical motion?
Air resistance acts against the movement of an object. Therefore it tends to reduce the velocity, whether is is vertical or otherwise. The higher the velocity, the higher the air resistance experienced by the object. Air resistance increases proportionally to the square of the velocity.
What is the effect of air resistance on projectile motion?
Projectile Motion with Air Resistance. It can be seen that as the air resistance strength increases ( i.e., as increases), the range of the projectile decreases. Furthermore, there is always an initial time interval during which the trajectory is identical to that calculated in the absence of air resistance ( i.e., ).
Why aren’t parabolic trajectories possible without air resistance?
Air resistance is not constant in magnitude or direction, so once you include air resistance trajectories can’t be parabolic any more. As for why it’s steeper on the way down, a good way to visualize this is to imagine something where air resistance completely dominates: a feather, for instance.
What is the net force of a projectile in air?
The absolute most simple case is that a projectile in motion through the air will experience a net force as follows: where F is the net force vector acting on the projectile, m is the mass of the projectile, g is the acceleration due to gravity (a vector that points down), b the drag coefficient, and v is the velocity vector of the projectile.
Is air resistance directly proportional to speed?
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.
