How High Can You Throw a Baseball? A Tennis Ball? A Football? A Golf Ball? *

Abstract
You can measure the approximate maximum height a thrown ball reaches by measuring the time it spends in the air. To do this project, you'll need at least one ball and a helper with a stopwatch. Your helper should start timing just as you release the ball, and stop right when the ball touches the ground. The height, h (in meters), can be calculated from the time aloft, t as follows:For height in feet, change "4.9" in the above equation to "16". (Wiese, 2002, 20–22.) Advanced project idea: If you've taken high school physics, you should be able to derive the equation above for yourself. Can you develop an explanation for how high you can throw different balls based on the forces acting on the balls?

Aerospace Engineer
Humans have always longed to fly and to make other things fly, both through the air and into outer space—aerospace engineers are the people that make those dreams come true. They design, build, and test vehicles like airplanes, helicopters, balloons, rockets, missiles, satellites, and spacecraft. Read more
Physicist
Physicists have a big goal in mind—to understand the nature of the entire universe and everything in it! To reach that goal, they observe and measure natural events seen on Earth and in the universe, and then develop theories, using mathematics, to explain why those phenomena occur. Physicists take on the challenge of explaining events that happen on the grandest scale imaginable to those that happen at the level of the smallest atomic particles. Their theories are then applied to human-scale projects to bring people new technologies, like computers, lasers, and fusion energy. Read more
Physics Teacher
Our universe is full of matter and energy, and how that matter and energy moves and interacts in space and time is the subject of physics. Physics teachers spend their days showing and explaining the marvels of physics, which underlies all the other science subjects, including biology, chemistry, Earth and space science. Their work serves to develop the next generation of scientists and engineers, including all healthcare professionals. They also help all students better understand their physical world and how it works in their everyday lives, as well as how to become better citizens by understanding the process of scientific research.
