PHYSICS 11 /20 Acceleration: 1. The pool ball shown below was photographed 8 times at equal time intervals. Is the pool ball's motion uniform? How do you know? Sketch a d vs t and v vs t graph, showing the general shape of each graph. you ilife abrera ed ebrloose 2. Make a sketch of what the pool ball's photos would look like if it were accelerating (both positively and negatively). 3. Acceleration is often a difficult term to understand. How could you best explain the A .8 acceleration of a car (and how it's different then velocity) to a non-physicist? I riquip 4. How can you recognize uniform motion on a d vs t graph? 5.
