Speed and Motion Graphs

Graphing Motion Watch the video and answer the following questions. Graphing Motion What type of graph did the teacher show first? distance chemical bar In his drawing, how many times did the bus stop? 4 2 3 A straight negative sloped line means constant acceleration focus deceleration A curved line means changing speed constant speed motion stops What is this Distance graph showing? Constant Speed slowing down Deceleration No Motion What is happening at point A? Deceleration Constant Speed Acceleration No Motion Which runner won the race (ran the farthest the fastest)? A B C Which runner stopped for a rest? Albert Bob Charlie On this Speed graph, during which interval is the object not moving? B to C D to E Point H only Point A only During which interval is the object decelerating? C to D F to G E to F A to B What is a straight line in a Distance graph indicate? Constant Speed Acceleration No Motion A speed graph shows us how the speed of a moving object - looks at one moment in time changes over time slows down at the end of a race On a speed graph, what does a downward sloping line indicate - the object is speeding up the object is turning around the object is slowing down the object is remaining in one spot An object "in motion" means the object must be - slowing down speeding up changing position stopping A distance graph can be useful when calculating - an object's speed an object's mass an object's location at any given time an object's volume
