Air resistance can affect the trajectory and range of a projectile.
A projectile's path can be described using two equations: one for x-coordinate (horizontal) and another for y-coordinate (vertical).
Projectiles are objects that move through space under the influence of gravity alone, with no other forces acting on them except air resistance.
The weight force is directed vertically downward towards the ground due to the gravitational pull of the Earth.
The angle between the horizontal line and the initial velocity vector is called the launch angle.
The angle of projection affects the range of a projectile.
Projectiles follow parabolic paths due to gravity acting on them.
The angle at which an object is launched affects its horizontal distance traveled, with higher angles resulting in shorter distances.
The horizontal component of velocity remains constant throughout the flight of a projectile.
The maximum height reached by an object is determined by its initial speed and angle of launch.
Time of fall/flight time is independent of the horizontal velocity component
Increasing the vertical height will increase flight time since horizontal velocity is constant.
45 degrees is the angle that produces the furthest range as it is in the middle of horizontal and vertical components of velocity
If the projectile is launched from a higher platform, a reduced angle (42-44 degrees) will produce a greater range
Drag force opposes the direction of travel
Drag is directly proportional to V^2 and A
Air resistance will opposevelocity
Lesserheight = shorter range because the time of flight is reduced
Projectiles have a gravitational force that is constant in magnitude and direction.
The horizontal component of displacement remains unchanged throughout the motion.
The zenithonly has a horizontal velocity as it remains constant
If an object is thrown at an angle, its maximum height is reached when the vertical speed is zero.
If the cross sectional area of an object is greater, it has a greater air resistance; therefore reducing its velocity
Air resistance increases with increasing surface area
Drag coefficient (D) depends on shape and orientation of the object
Terminal velocity is achieved when the weight of the object equals the aerodynamic drag force acting upon it
Time decreases from the affects of air resistance.
When airresistance is acting, time is reduced going to the zenith but slightly increased when going from the zenith to the ground but overall time is still reduced.
