Part I. Check your understanding. 1. Does a negative acceleration always indicate that the object is slowing down? Explain. Encode your answer here (you can add more space if needed)... 2. Enumerate 3 real phenomena (or situations) for each of the following motions: (a) free-fall, (b) projectile, (c) uniform circular. Encode your answer here (you can add more space if needed)... 3. A huge rock and a light feather are dropped at the same time from the same height above the ground. Which object would reach the ground first if air resistance is neglected? Encode your answer here (you can add more space if needed)... 4. Compare the following motion: (i) a tennis ball drop from the edge of a table; and (ii) a tennis ball rolling horizontally towards the edge of the table and falls to the floor. Encode your answer here (you can add more space if needed)... page 1 | Assignment No. 2 5. Can an object have a nonzero acceleration even if its speed is constant? Explain how. Encode your answer here (you can add more space if needed)
