Question

Please answer the following 6 questions, Greatly appreciated.

1) When the net force on an object is zero, the object will ? Select one (a) travel in a straight line (b) travel at a constant speed (c) both a and b (d) neither a or b

2) When the net force is zero, the object’s acceleration is____ a____ , and its velocity ___b____ . a) zero / non-zero (circle one) explain your answer. b) is constant / will change (circle one) explain your answer.

When the net force is not zero, the object’s acceleration is____ c_____ , and its velocity ______d______ . c) zero / non-zero (circle one) explain your answer. d) is constant / will change (circle one) explain your answer.

3) Can something accelerate without a force acting upon it? Why or why not?

4) Can you accelerate without changing your speed? Why or why not? (Think very carefully about this)

5) Give an example where something travels in a straight line while a force is acting on it. (besides net force is zero)

6) Give an example where something travels at a constant speed while a force is acting on it. (besides net force is zero)
