This is Newton's First Law: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. An example would be the rock stops the skateboard and makes the test tube fall. This applies to our rocket because the rocket would stay on the launcher until it is launched. Then when the rocket is launched, the rocket will stay in motion until air resistance acts on the rocket, slowing it down.
This is Newton's Second Law: Acceleration is produced when a force acts on some mass. The acceleration depends on the strength of the force and the size of the mass. The law can be stated: F= MA. We can use the mass of the rocket and the acceleration of the rocket to find out it's force. The mass of the rocket is 92.5 grams and the acceleration is 6.5 m/s^2. So when we multiply them together, we get the force, which is 601.25 N.
This is Newton's Third Law: For every action there is an equal and opposite force. This means that when our rocket is launched, the rocket goes up. The opposite force is the air that is being pushed out of the rocket. The force of the air is the same as the rocket, and it is in the opposite direction.
