11) A sports car and a fully loaded semi truck pull side by side at a red light. Using your knowledge of acceleration, predict which will accelerate faster when the traffic light turns green. Cite reasons for your answer.

Answer 1

1) False, an unbalanced force is needed or the object will stay in place.
2) True, weight is the amount of force gravity is putting on an object.
4) True, net force is equal to the mass of the object multiplied by the acceleration of an object.
5) False, however I'm not completely sure on this one.
6) Force is any interaction that will change the motion of an object.
7) vertical
8) horizontal
9) horizontal.
10) vertical or both.
