You take your dog on a walk to a nearby park. On the way, yourdog takes many short side trips to chase squirrels, examine fire hydrants, and so on. When you arrive at the park, do you and yourdog have the same displacement from home? Have you and yourdog traveled the same distance? Explain
Does acceleration depend on the speed of an object? Why or why not? Give an example of a slow object having a larger acceleration than a fast object. Can anyone think of an example of an object moving in such a way so that it is accelerating while having zero velocity?
Can an object have a negative acceleration and be speeding up? If so, describe a possible physical situation and a corresponding coordinate system. If not, explain why not.
One car travels due east at a steady 40 km/h, and a second car travels due north at a steady 40 km/h. Are their velocities equal? Yes, they are both moving in positive directions. No, they are accelerating differently. No, they have different directions. Yes, they have the same speed.
One aeroplane travels due north at 300km/h while another travels due south at 300km/h. Are their speeds the same? Are their velocities the same? Explain.
A train makes a journey in which at a point on its trajectory a speed of 80.0 km / h is measured towards the east, while half an hour later the speed is 65.0 km /h towards the east. Can you calculate the average acceleration in this half hour of travel? a) No, because we do not know the starting position or the final position of that half hour of travel. b) No, because we do not know how the direction of the train changed in the other moments of that half hour of travel. c) Yes, and it has a magnitude of 30.0 km/h?? westward. d) Yes, and it has a magnitude of 30.0 km / h²2? to the east.
Can a car traveling west simultaneously have an acceleration pointing east? If not, explain clearly why not. If yes, give a clear example of a situation in which it could occur.
Can an object with constant acceleration reverse its direction of travel? Can it reverse its direction twice? In both cases, explain your reasoning.
Which of the following statements describe an object moving with 1.0 m/s? acceleration? O The object spends one second to cover one meter. O The object moves with increasing acceleration. O The object covers distance linearly. O The object adds one meter per second in its velocity every second.
Is it possible for an object to have zero velocity and constant nonzero acceleration? O Yes, but only if it is not moving at all. O No, if its velocity is zero its acceleration must also be zero. Yes, all objects with zero velocity have nonzero acceleration. Yes, but its velocity must only be zero for an instant. O No, if its acceleration is not zero its velocity cannot be zero.
You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90 km/h. Is your average speed for the entire trip from A to C 80 km/h? Explain why or why not.
Which one of the following statements is true? (a) If a car is traveling eastward, its acceleration must be eastward. (b) If a car is slowing down, its acceleration must be negative. (c) A particle with constant acceleration can never stop and stay stopped.
