Projectile Motion of an Object
Exploration
When an object is in free fall, the only force acting on the object is gravity. In general terms, an object moving upward is not considered “falling,” however, if gravity is the only force acting on the object (air resistance being negligible) then the object is in fact in a state of free fall. The projectile motion of an object is the trajectory of an object in free fall near Earth’s surface after being thrown or launched in the air. The curved path of the projectile is under the effect of gravity only after being launched.
Objective
In this experiment, students will:
1. Explore the relationship between acceleration, altitude, and speed of a projectile object as it is thrown upward into the air.
2. Explore concepts of free fall and how the net force of gravity affects the object as it travels both up and down.
3. Use three graphs to illustrate the derivative and integral relationships of position, speed, and acceleration.
