Forces Test Review

Which of the following statements are true of the concept of force?

• A force is a vector quantity; there is always a direction associated with it.

• One Newton of force will cause a 1 kg object to accelerate 1 m/s2

• A force is a push or pull exerted upon an object which results from the interaction of that object with its environment.

• all of the above.
