We started off at 0 velocity, obviously because it was stationary, and at the bottom, it was 100 meters per second. Develop mathematical models involving linear, power, andor inverse relationships among variables. Neglecting air resistance, the only force acting on the projectile is the force of gravity and we have in essence a freely falling object see figure 1. Teaching projectile motion to eliminate misconceptions anne prescott university of technology, sydney michael mitchelmore macquarie university, sydney student misconceptions of projectile motion are well documented, but their effect on the teaching and learning of the mathematics of motion under gravity has not been investigated.
