Describing Motion

1-10) Sort the type of quantities into the correct category. See Slide 3 for scalar quantities. Scalar Quantities distance speed time mass density Vector Quantities displacement velocity acceleration force weight 11) When moving from place to place, you can define a vector as one of the directions you travel. Your vector changes when you change direction. Knowing this, your final final displacement is dependent on _ the order of the vectors the sum of the vectors the product of the vectors is not dependent on the vectors 12) A person starts at A and walks to B, then C, D, then back to A. What is the total distance they traveled? 0 m 8 m 12 m 24 m 13) A person starts at A and walks to B, then C, D, then back to A. What is their total displacement? 0 m 8 m 12 m 24 m 14) What is the total distance the object traveled according to the graph? 0 meters 20 meters 40 meters 15) What is the total displacement of the object according to the graph? 0 meters 20 meters 40 meters 16) What is the average speed of the object according to the graph? 0 m 0.6 m 1.3 m 1.5 m 18-21) Match the speeds to the correct line segment. You will need to use the equation for speed on slide 5. Segment A 0.3 m Segment B 0.5 m Segment C 0 m Segment D 2 m 22) Which segment would have a negative (-) velocity to indicate a change in direction? A B C D The police car that is traveling 45 mph W is pulling over a speeding car (blue) that is traveling 75 mph W. (West is to the left).27) What is the relative velocity of the blue car if the police car is the frame of reference? In other words, how fast is the blue car going in comparison to the police car? 0 mph 30 mph W 30 mph E 75 mph W 28) What is the relative velocity of the police car if the blue car is the frame of reference? 0 mph 30 mph W 30 mph E 45 mph E 29) What is the relative velocity of the police car if the stationary building is the frame of reference? 0 mph 30 mph W 30 mph E 45 mph W
