Question

Medal for help!
Can someone explain to me how exactly the launch angle affects the trajectory and final range of a projectile?

Answer 1

The launch angle acts as the distribution of the total velocity between horizontal and vertical components.

A launch angle of 0 degrees is a horizontal trajectory.

A low launch angle (0 degrees < launch angle < 45 degrees) will mean that the horizontal component of the projectile's velocity will be larger than the vertical component of the projectile's velocity.

A launch angle of 45 degrees means both the vertical and horizontal components of the projectile's velocity are the same.

A high launch angle (45 degrees < launch angle < 90 degrees) will mean that the vertical component of the projectile's velocity will be larger than the horizontal component of the projectile's velocity.

A launch angle of 90 degrees is a vertical trajectory.


The range of a projectile is dependent on both the horizontal and vertical components of the projectile's velocity. The vertical component will affect how long the projectile remains in the air and is able to travel. The horizontal component will affect how far the projectile will travel in the time obtained from the vertical flight calculation.

Answer 2

I just want to make sure I'm fully understanding this.

So when you said "A launch angle of 0 degrees is a horizontal trajectory."
---- That means that it will launch in a straight line horizontally.

"A low launch angle (0 degrees < launch angle < 45 degrees)..."
---- it will launch far but not very high.

"A launch angle of 45 degrees means both the vertical and horizontal components of the projectile's velocity are the same."
---- The height and distance will change at the same rate.

"A high launch angle (45 degrees < launch angle < 90 degrees)..."
---- it will launch high but not very far

"A launch angle of 90 degrees is a vertical trajectory."
---- it will only shoot straight up.

Answer 3

Yes, that is correct.

Okay. Thank you so much!
