  1. Kinetic Something Pages 1 - 15

  2. Units • Metric system (SI system) Mega- 1000000x Kilo- 1000x Deci- 10x Centi-.01x Milli-.001 Micro-.000001 English system 1 ft - 12 inch 1 yard - 3ft. 5280 ft- 1 mile

  3. Vectors and Scalars Scalars – quantities that are associated with magnitude (ex. move 500 ft) Vectors – quantities that are associated with both magnitude and direction (ex. Move 500 ft to the right)

  4. Kinematic equations (One dimensional) • Velocity = initial velocity + (acceleration x time) • Change in Position = .5(initial velocity + velocity) x time • Change in Position = initial velocity x time + .5 acceleration x (time squared) • Velocity squared = (initial velocity squared) + 2 x acceleration x change in position

  5. Gravity • Acceleration of gravity 9.8m/s/s (10m/s/s) or 32ft/s/s

  6. Two Dimensional Motion • Now you’re applying y (vertical direction) and X (horizontal direction) • Velocity y= initial velocity of y + the acceleration of y) X time. • Change in y = .5 X (initial velocity of y + the velocity of y) X time • Change in y = initial velocity of yX time + .5 acceleration of yX (time squared) • velocity of ysquared = initial velocity of y squared + 2 X acceleration X change in Y position

  7. Projectile Motion • Any object that has motion in both vertical and horizontal directions and is influenced only by gravity while in the air. (ex. of Two Dimensional motion)
