# how to make newtons first law of motion working model for science exhibition

This simple rocket demonstrates the basic principle of Newton’s first law of motion, as the rocket remains at rest until an external force (the expulsion of water) acts upon it, causing it to move forward.

## Newton’s First Law of Motion

Newton’s first law of motion describes how an object behaves when no force is acting on it.

For example, rockets remain stationary until a force is applied to move them. Once they are in motion, they will not stop until an external force is applied.

Formula

F = 0

F represents the net force acting on a object

Newton’s first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

A rocket can demonstrate this law when using the principle of action and reaction, as in the case of a syringe rocket. Here’s how you can create a simple syringe rocket using cardboard, paper, and syringes:

## Materials needed:

1. Cardboard
2. Paper
3. Syringes (preferably large ones)
4. Drinking straws
5. Tape
6. Scissors
7. Water

## Step by Step Instructions:

1. Prepare the rocket body:
• Roll a piece of paper into a tube to form the body of the rocket. Secure it with tape.
• Cut out fins from cardboard and attach them to the bottom of the rocket to stabilize it during flight.
