Week 21 pg. 34 For each of the following write either ‘change in velocity’, or ‘no change in velocity’: and a reason why A car speeding up to get on the freeway A car braking to avoid a crash A horse running 18 m/s in a straight line A kid spinning around in circles For each of the following write either ‘change in speed’, ‘change in direction’, ‘change in both’, or ‘none’ You are walking home. You are running the mile in P.E. A train travels 14 m/s in a straight line. You are riding on a ferris wheel at the fair. You are at home asleep in bed.
Week 21 pg. 34 What is the velocity of an object traveling 14mi/hr South? How can you change velocity? If a car stops at a stop sign, is that a change of velocity? Why or why not? If you are roller skating down the sidewalk and swerve to avoid a small rock, have you changed velocity? Why or why not? A car is travelling 50 m/s West, after 5 s, the car is travelling 30 m/s West. What is the acceleration of the car?
