Equations of motion index
This folder collects the constant-acceleration tools used in introductory Kinematic problems. These equations describe motion; they do not explain the forces causing it. For causes, move to Newton’s Laws of Motion.

When this method applies
Use these equations when acceleration is constant over the interval. Typical examples: vertical motion near Earth’s surface ignoring air resistance, or one-dimensional motion with a constant net force.
If acceleration changes with time or position, start from the derivative relationships in Kinematic and integrate instead of memorising SUVAT.
