1. Define force.
2. Define 1 newton.
3. What do you mean by interaction?
Answers
Answer - 1
A push or a pull on an object is called force. Example of force are : kicking a football, lifting a bucket, hitting a ball with a bat. In all these examples, either a push or a pull is involved. So, to move an object either a push or pull is involved.

The Newton is a SI unit of force. It is denoted by the letter N. It is equal to the force that would give a mass of one kilogram an acceleration of one metre per second per second, and is equivalent to 100,000 dynes. To feel how much force one Newton (1N) is, place a 100 gram weight measure on your plam and hold it Parallel to the ground. The force exerted by 100g weight on your palm is nearly one Newton (1N). Similarly, when you place a 200 gram weight on your palm, you experience a force nearly 2N.

Force due to Interaction : If a book is lying on a table, it doesn't change it position on it's own unless an external force is applied. To bring the book in motion we have to interact (touch) with the book either by pulling or pushing it, that is applying force to move it. So, we may conclude that without an interaction or touch we force cannot be applied to change it's state. The interaction may be either our efforts or by other object in contact.
Explanation:
physical strength or power.
push or pull is correct answer
is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second. One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the foot-pound-second (English, or customary)
communication or direct involvement with someone or something.
