Two children are pulling on a rope. One child is pulling with a force of 5 N to the left while the second child is pulling with a force of 8 N to the right. What is the result?
The rope remains in place.
The rope moves to the right.
The rope moves to the left.
The rope has a balanced force on it.
Which statement about acceleration is always true?
The unit m/s is the SI unit for acceleration.
Either a change in speed or a change in direction causes acceleration.
For objects to accelerate they must always speed up.
Both speed and direction must change to cause a change in acceleration.
