Projectile Motion Photo Project Candace

This picture illustrates projectile motion by showing a ball bouncing on the ground. This picture shows projectile motion because the ball was moving at a constant rate when it was falling and when it reaches its peak it has 0 velocity, then goes back to the constant rate making the parabola shape. I had set camera shutter speed 1/20 and dropped the ball from a height of 3 centimeters.

This is a video clip of the cartoon Road Runner. At 0:44, Wile E. Cayote walks off a cliff and continues to walk in mid air for at least 2 seconds. While loitering in mid air, Wile E. Cayote takes a look down, realizing he is not standing on solid ground, and finally starts to decend down the cliff. This is when the 9.8 m per second takes over. Our reasoning as to why this is impossible is because of the existence of gravity. Gravity is defined as the natural force of attraction exerted by a celestial body, such as Earth, upon objects at or near its surface, tending to draw them toward the center of the body. Basically, what that means is that without gravity, one would float off into the atmosphere without ever coming down - like how Wile E. Cayote was floating in mid air almost as if gravity was not present. Of course, considering that gravity is always present in the Earth's atmosphere, floating in the air like that is impossible.

In our projectile motion photo, we decided to throw a ball. We determined that this photo demonstrated a projectile motion due to many reasons. One reason that this photo demonstrated projectile motion is, when the ball is first thrown it is moving at a constant rate. And the slope for this constant rate is, 2.399 m/s. Our final reason that this photo demonstrates a projectile motion is, when the ball is dropping to the ground it is not moving at a constant rate. We know this because, we drew a best fit line through the y points in a graph. And the estimated slope was -1.269 m/s.

Projectile motion can be seen almost anywhere - even Millennium Park. This is a picture of the Crown Fountain in Chicago. The towers are fifty feet tall and has slits for drainage to drain up to 11520 US gallons of water per minute. The water is flitered, pumped, and recirculated through the fountain.

Mathematicians describe the shape of a projectile motion as a parabola. The shape of the water spewting out of the Crown Fountain is definitely an accurate portrayal of that shape. This is a photo which captures real life projectile motion.
