Projectiles

I was playing tennis with my dad and remembered I had to do a blog on projectile motion. So I took the tennis ball and took a picture of it because I couldn’t take a picture of it in the air moving while I was playing. Projectile motion is again when an object is thrown or shot or bounced or put in the air and it moves along a curved path like a parabola. That path of motion is called the trajectory. Depending on how far and how fast something is moving in the air will determine how curved the line is. The line that a tennis ball follows when it is served is most of the time more of a flatter curve because it is hit hard and as straight of a line as possible. When you look at the velocity vs. time graph of the tennis ball moving it should be moving relatively constantly.
