1-D Projectile Motion [IB Physics SL/HL]

This podcast episode introduces and defines one-dimensional projectile motion, detailing its characteristics and applying the theory to two examples. The speaker explains that projectiles are objects acted upon only by gravity, accelerating downward at 9.8 m/s² in the absence of air resistance. The trajectory of a projectile launched upward and landing at the same height is symmetrical, with zero instantaneous velocity at maximum height, while acceleration remains constant. The episode demonstrates solving for initial velocity and time in the air using uniform acceleration formulas and concludes by qualitatively discussing the impact of air resistance on projectile flight, noting it leads to a lower maximum height, shorter flight time, and slower final velocity.
