Let's start with a model and then see if it works. Here is a common way to calculate the magnitude of the drag force on a moving object.

However, our experience with moving objects is primarily based in a gravity-constrained real-world context. Objects do not spontaneously accelerate, decelerate, or curve midway through their path.

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or ...

Stuff is constantly falling—off tables, out of bags, from the sky. Let's explore the science of all things tumbling downward.
