Introduction to Vectors and Scalars

Key concepts in the study of mechanics and motion are vectors and scalars. This overview gives an introduction to both, with examples and links for learning more. Continue reading

Free-Falling Objects

An object at rest, dropped from a distance above the Earth, will accelerate downward at a constant rate due to gravity. Learn with this Formula Solver how to calculate this downward acceleration using your own distance, time, and final velocity values. Continue reading

Acceleration and Deceleration

Acceleration is the increase of velocity over time, while deceleration is the decrease of velocity over time. This Tab-Tutor Series program will help you learn how to calculate them both — check out the glossary review and homework checker, too! Continue reading
