# Physics 9-23-13 Angular Projectile Motion

PHYSICS – I missed you today! How’d you do with the virtual me? Here’s the vodcast that you watched on angular projectile motion – well, a lot of homework review and then angular projectile motion.

The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!

# Physics Help Session Wednesday Morning, 7:15 A.M.

And I promise not to start with the really hard problems this time! How’re the problems going? You can do this!! If you are talking angular projectiles, the resultant velocity is actually made up of two things – horizontal velocity and vertical velocity. The horizontal velocity never changes, the vertical velocity has a different direction going up and coming down, but it has the same speed at equal levels. Now, if you’re talking horizontal projectiles, the resultant velocity is the same as the horizontal velocity of the gun, because that’s the only kind of initial velocity it has!

Draw a picture, write what you know, resolve the resultant velocity into vertical and horizontal, find formulas that fit (because it will hardly ever be solved with just one) and go for it!! Capisce? ðŸ™‚ Oh, by the way – don’t forget the conceptual stuff!

# Physics 9-28-11 Angular Projectile Problems

PHYSICS – Don’t give up! I told you they were tough, but you can do it! Here’s the short review we did Wednesday of a couple of angular projectile motion problems. Don’t give up!! ðŸ™‚

# Physics 9-27-11 Angular Projectile Motion

PHYSICS – Great job today! Here’s the lecture from Tuesday on angular projectile motion. The number one thing to remember – Never use the resultant velocity to do more than find the vertical and horizontal components! And vertical is vertical, horizontal is horizontal and don’t ever mix the two!
