Projectile Motion
Storyboard Text
- uniformly accelerated motion If an object's speed (velocity) is increasing at a constant rate then we say it has uniform acceleration.
- Some uniform accelerated motion examples include a ball rolling down a slope, a skydiver jumping out of a plane, a ball dropped from the top of a ladder and a bicycle whose brakes have been engaged.
- Remember this trip is for you guys to see how these concepts work in real life! Now does anyone remember what a horizontal component is?
- Ha! That is easy. The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
- Oh, I remember! That was when we did the experiment with the half-full containers! When I moved my fingers in a circular motion, the water was always highest on the side opposite of me.
- Teacher, I forgot what the vertical component is.
- Hmm example, The ball's speed is the magnitude of its velocity vector, and when you include a direction to that speed, you get the velocity vector v.
- There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.

- Since Lily was sleeping on the bus, give us the honors of explaining what combined component is
- Very good! Remember when we get back you'll all have to do a essay on some examples from the park on today's lesson.
- In combined component, There are the two components of the projectile's motion - horizontal and vertical motion
- Later that day...
- So honey, how was the field trip? Did you learn anything new?
- We learned about projectile motion!
- The teacher said it was an object's speed (velocity) is increasing at a constant rate then we say it has uniform acceleration.
