Which of the following best describes a noncontact force

Answer:

A force that is able to act at a distance best describes a noncontact force.

Explanation:

A non-contact force is a force that is exerted between two objects that are not in contact with each other. It is also the force that comes into play when there is no physical interaction between two objects. Gravity is an example of non-contact force.

Consider a situation where you throw an object into the air. This object reaches the maximum height and falls back to the ground. This is due to the non-contract force(Gravity). Hence a non-contract force is a force that acts at distance. The other examples of non-contact forces are magnetic force,  electrostatic force, nuclear force.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
