# 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

# Speed and Velocity

Speed is a scalar quantity measuring distance travelled over time, while velocity is a vector quantity measuring displacement over time. This Tab-Tutor Series program will help you learn how to calculate them both — check out the glossary review, too! Continue reading

# Displacement and Distance

Displacement is a vector quantity having both magnitude and direction, while distance is a scalar quantity having only magnitude. This Tab-Tutor Series program will help you learn how to calculate them both — check out the glossary review, too! 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
