Projectile Motion question

[dream chaser]

Hi Guys,

Just a quick question. Is it possible to change the launch angle of the projectile without changing its initial velocity and is it possible to change the initial velocity of the projectile without changing the launch angle?

All replies will be very much appreciated

Thanks

Hey there!

Yes, it is possible to do both. The initial velocity V of some object X and its launch angle θ can be modified independently of each other. If one is changed, and the other kept constant, all that really does is change the initial horizontal velocity and initial vertical velocity, and as a result, the range and the time of flight are both changed.

In short, changing either the initial velocity or the launch angle can be done independently, affecting range and time of flight, and not the other parameter you've chosen to keep constant.

Hope this helps
