Question

day 2 of rocket lab- questions: answer the following questions in complet 1. define the first law of motion: discuss how this lab demonstrated the first law of motion: 2. define the second law of motion: discuss how this lab demonstrated the second law of motion: the third law of motion: discuss how this lab demonstrated the third law of motion:

Explanation:

1. The first law of motion, also known as the law of inertia, states that 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 un - balanced force. In the rocket lab, if the rocket is at rest on the launch pad, it will remain at rest until the thrust force from the engines overcomes the force of gravity and other resistive forces.
2. The second law of motion is expressed as \(F = ma\), where \(F\) is the net force acting on an object, \(m\) is the mass of the object, and \(a\) is the acceleration. In the rocket lab, as the mass of fuel is burned and ejected from the rocket, the mass of the rocket changes. The thrust force from the engines causes an acceleration of the rocket according to this law.
3. The third law of motion states that for every action, there is an equal and opposite reaction. In the rocket lab, the hot gases are ejected downwards from the rocket engines (action force), and in response, the rocket experiences an upward thrust force (reaction force) which propels it into the air.

Answer:

1. The first law of motion (law of inertia): 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 un - balanced force. In the rocket lab, a stationary rocket on the launch pad remains stationary until the thrust force overcomes gravity and other resistive forces.
2. The second law of motion: \(F = ma\), where \(F\) is the net force, \(m\) is mass, and \(a\) is acceleration. In the rocket lab, as fuel burns and mass changes, the thrust causes acceleration according to this law.
3. The third law of motion: For every action, there is an equal and opposite reaction. In the rocket lab, hot gases ejected downwards (action) cause an upward thrust force on the rocket (reaction) propelling it into the air.
