  1. Kinematic graphs of two cars’ motions X (m) Your Group Project: t (s) Velocity Calculations v (m/s) t (s) Motion Diagram: Word Description:

  2. When you find the slope of the line on an x vs. t graph, you have found VELOCITY.

  3. (6 min, 500 m) 0min 200 m 6 min 500 m 500 m 200 m (0min, 200 m) 6 min 0 min v = 300 m/ 6 min = 50 m/min 1 2 3 4 5 6

  4. 0 hr 0.5 km 3 hr 2 km 2 km 0.5 km 3 hr 0 hr v = 1.5 km/ 3 hr = 0.5 km/hr

  5. ( ti, x i ) ( t f , x f ) ( 0 hr, - 1 mi) ( 3.5 h, 0.5 mi) V = x f x i ( 0.5mi - - 1 mi ) ( 3.5 hr - 0 hr ) t f t i v = 1.5 mi / 3.5 hr = 0.43 mi /hr

  6. ( ti, x i ) ( t f , x f ) ( 0 s , 400 cm) ( 40 s, 600 cm) V = x f x i (600 cm – 400 cm) ( 40 s - 0 s ) t f t i v = 200 cm/ 40 s= 5 cm/s

  7. ( ti, x i ) ( t f , x f ) ( 0 min, - 0.4 km) ( 4.5 min, 0 km) V = x f x i (0 km - - 0.4 km ) ( 4.5 min - 0 min ) t f t i v = 0.4 km / 4.5 min = 0.08 mi /hr
