Free fall motion is when the object falls and the only force acting on the object is the force of gravity. In this chapter we are going to look at the motion of objects that are either projected, thrown, or shot directly into the air, be it vertically upwards, downwards or when objects are dropped. Up until now, we have only dealt with projectiles that were fired horizontally. When a particle is projected in the air with some speed, the only force acting on it during its time in the air is the acceleration due to gravity g. Projectile motion is a special case of twodimensional motion. Yet, most projectiles are actually shot at an angle. For the purpose of our study, we must break up the twodimensional motion into two onedimensional motions. Instruct each group to repeat the experiment on different angles of inclination.
