Notes and vocab Chapter 3 Projectile motion Throw a baseball and the path it follows is a curve. This curve is a combination of constant-velocity horizontal motion and accelerated vertical motion. It is a nonlinear motion-motion along a curved path. Vector and scalar quantities Pictures are powerful tools. Vector quantity: A quantity that requires both magnitude and direction for a complete description. Velocity differs from speed in that velocity includes direction in its description. Velocity is a vector quantity, as is acceleration. A quantity that can be added, subtracted, multiplied and divided like ordinary numbers are scalar quantity. Scalar quantity is completely described by magnitude only. Velocity Vectors
