Document Summary
Scalar: quantity with only a magnitude (distance, mass, volume: when adding just straight addition or subtraction with magnitudes. Vector: quantity with magnitude and direction (force, displacement: directions must be considered when adding. Co-linear vectors: vectors acting along the same line with different directions: adding: a + b + c + d = ad. Vector decomposition: any vector can be decomposed into an arbitrary set of vectors that will add up to original vector. Vector resolution: two vectors projected horizontally and vertically can be resolved into a resultant vector. Basic trigonometry: soh cah toa (for right triangles) Biomechanics: study of biological systems from a mechanical perspective: branch of sports medicine. Linear kinematics: distance (d) / displacement (change in d, speed (s) / velocity (change in v, acceleration (a): rate at which velocity is changing. Projectile motion: maximize horizontal distance, vertical distance, accuracy and accuracy with speed: factors to consider, release angle, release velocity, release and landing height.
