Speed and Velocity

You are giving another student directions to your house. What would help the student most? if you describe the fastest way if you tell about your neighbors if you identify reference points along the way What is the definition of motion? a change in position over time the speed and direction location of an object An elevator traveled 15 floors (150 meters) at a speed of 4.5 m What additional information do we need to determine the velocity? how many times it stopped. the direction in traveled the mass of the elevator An athlete ran a 5 km race at an average speed of 8 km If she stopped to tie her shoe during the race, why would her average speed be less than 8 km Her distance was longer Her total time increased after she stopped. Her total time decreased after she stopped. In a swimming race Mike swam the first 50m in 42s. He swam the second 50m in 40s. What was his average speed? 0.82m 1.19m 1.22m Which one of these units would you use to measure distance? grams seconds meters The _ of an object describes the speed and direction it is going. motion speed velocity The location to which you compare other locations is called a: reference point spot vector An airplane travels 3,850km in 5.5 hours. What is the speed? 700 km 700 km 700 hours How do we represent a vector? arrow circle map In order to get an object's velocity we would measure the speed then include the direction.
