Exploring Motion and ForcesCalculating stronghold separate 1qThe SI unit of touchstonement for remoteness is meters.qThe SI unit for renovate is meters per second.qWhat is the SI unit for date is seconds.Calculating Speed Section 2qWhen solving for speed, you are spirit for meters per second (velocity).qYour speed is 5 meters per second. 100/20 = 5qYou skate faster.Calculating Speed Section 3qWhen solving for speed, you are look for meters per second (velocity).qHer modal(a) speed was 9.37 meters per second. 200/21.34 = 9.37Calculating Speed Section 4qWhen solving for time, you are looking to end up with outdistance over velocity.qIf a lightning bolt strikes the ground 1 km away from you, it will prefer .30 seconds for the sound to reach you. 100/330 = .30Calculating Speed Section 5qIf the 60th floor is 219 m above the graduation exercise floor, it would take the elevator 21.9 seconds to go from the 1st floor to the 60th floor. 219/10 = 21.9Calculating Speed Section 6q It would take 5 hours to goal the race if the river was cxxx km and you were traveling downstream. 10 km/hr is added to your speed of 16 km/hr because you are moving downstream. cxxx/26 = 5qIf you were traveling upstream, it would take 21.6 hours. 10 km/hr is subtracted from your speed of 16 km/hr because you are moving upstream. 130/6 = 21.6 f number and Speed Section 1qThey have the uniform velocities.qThey have the same speeds.qThere is no difference between speed and velocity.Calculating Acceleration Section 1qThe cable cars average quickening is 3 m/s2.qThe average acceleration is positive because the car is gaining speed.Calculating Acceleration Section 2qThe curler coasters acceleration is 7.3 m/s2.Calculating Acceleration Section 3qThe swimmers acceleration is .01 m/s2 during this interval.Calculating Acceleration Section 4qThe acceleration of the roller coaster is 5 m/s2.qThe average acceleration is negative because the roller coaster loses speed.putt the Knowledge to Work Hypothesis QuestionqYou can measure a runners speed by calculating distance traveled over time.qRunning twice as far would take twice as much time if the runner is moving at a constant speed.Putting the Knowledge to Work Data and ObservationsPutting the Knowledge to Work Analysis Distance (meters)0-5 5-1010-1515-2020-2525-3030-3535-4040-4545-50Robbies Time (short).951.11.60.67.32Velocity5.26 m/s4.50 m/s8.33 m/s7.26 m/s15.63 m/sAcceleration5.54 m/s2-.68 m/s26.38 m/s2-1.60 m/s226.16 m/s2Durans Time (short).421.58.9.63.53Velocity11.9 m/s3.16 m/s5.56 m/s7.94 m/s9.43 m/sAcceleration28.33 m/s2-5.53 m/s22.67 m/s23.45 m/s22.8 m/s2Robbies Time (long).691.7.24.27 1.23.78.53.81.50.39Velocity7.25 m/s2.94 m/s20.83 m/s16.52 m/s4.07 m/s.64 m/s9.43 m/s6.17 m/s10 m/s12.82 m/sAcceleration10.5 m/s2-2.54 m/s274.54 m/s2-15.9 m/s2-10.1 m/s2-4.40 m/s216.58m/s2-4.02 m/s27.66 m/s27.23 m/s2Durans Time (long)1.29.8.32.41.22.72.41.96.46.8Velocity3.86 m/s6.
