Question

A student made the table shown to list some contact and non-contact forces.

Answer 1

Answer:

No. 5

A. The student applies a non-contact force on the box

No. 6

A. Net force

Explanation:

The statement that best explains why the table is incorrect is: "The student applies a non-contact force on the box". This is because what actually moves the box is a contact force. A non-contact force is the force which acts on an object/body without coming near it or touching it. But in the case of the student and the box, a contact force exists.

The sum of all forces that act on an object is called "Net Force". The net force becomes a single force which replaces the effect of the original forces on the object's motion.
