The position-time graph for an object that remains still over time would be represented by **a horizontal line**. This indicates that the position does not change as time progresses.
Answered by GPT-4o mini
The correct statement about forces is: **Forces have both magnitude and direction.** This makes them vector quantities.

A force is best described as **a push or a pull on an object.**
Answered by GPT-4o mini
The situation that describes a non-contact force acting on an object is **none of the provided responses**, as all the options involve contact forces.

However, a typical example of a non-contact force would be gravity or magnetic force. If you are looking for an option that could be contextualized, you might consider the force of gravity acting on the textbook when a person is picking it up, but in that context, the act itself involves contact.
