Question

select the correct answer. which statement about forces is true? a. forces are defined by strength but not direction. b. forces are defined by direction but not strength. c. forces are defined by both strength and direction. d. forces act only on objects that are in contact.

Explanation:

A force is a vector quantity. Vector quantities have both magnitude (strength) and direction. For example, when we push an object, we need to know how hard (strength) we push and in which direction. So forces are defined by both strength and direction.

Answer:

C. Forces are defined by both strength and direction.
