This animation gives you a quick visual for parabolic motion. It also shows you graphs of how the velocity and speed vary in each dimension.

This video shows parabolic motion by tracing the path of a ball that has been thrown.

This video shows you how to determine the maximum height of projectile moving in two dimensions. He uses “d” rather than “x.” in the equations. He also doesn’t follow significant figures rules.

This video shows one range equation problem. He uses “delta_x” rather than “range” in the equations. He also doesn’t follow significant figures rules.

This video shows another range equation problem. He uses “delta_x” rather than “range” in the equations. He also doesn’t follow significant figures rules.

This video mimics the archery event where the target is dropped when the archer fires. The target is a toy monkey, and a ball is fired from a launcher instead of an arrow being shot from a bow.

This video that motion in the vertical dimension doesn’t affect motion in the horizontal dimension.

This is a clip from the Mythbusters show demonstrating that motion in the vertical dimension doesn’t affect motion in the horizontal dimension.

This video shows you how to split a two-dimensional projectile motion problem into two one-dimensional problems.

This video solves a 2-dimensional motion equation where the range equation doesn’t apply.

This video solves another 2-dimensional motion equation where the range equation doesn’t apply.

Projectile Motion with Air Resistance

This is the first of a four-part series on analyzing projectile motion with air resistance.
