Projectile Motion


 * Horizontally-launched Projectiles

Go to the **[|**Gravity Simulation**]
 * 1. Increase the horizontal speed of the blue ball to 25, 50, 75, and 100 m/s. How does this effect the time it takes the ball to fall to the ground? Why do you think this is?**

** 2. How does the downward component of the motion of a ** **projectile compare to the motion of free fall?** ** 3. At the instant a ball is thrown horizontally over a level range, a ball held at the side of the first is released and drops to the ground. If air resistance can be neglected, which ball - the one thrown or the one dropped from rest - strikes the ground first?

4. A cart is rolling at a constant speed along a fricitonless track when it tosses a ball straight up in the air. When the ball lands, it will land a. in front of the cart b. behind the cart c. back in the cart**


 * Now watch **[|**this video**]


 * 5. Was your prediction correct? Come up with an explanation for why this happened.

6. A plane is flying eastward at a constant velocity when it drops a package. Then the package hits the ground, it will land: a. in front of the plane b. behind the plane c. directly underneath the plane**

Now watch [|this animation]


 * 7. Was your prediction correct?

8. N **eglecting the effects of air resistance, explain why after being thrown, the package remains directly below the plane and the ball remains directly above the truck.
