Andrew plays trumpet in the concert band. He holds the trumpet still at his side until it is time for him to play. When it is time, he brings the trumpet up to his mouth and starts to play. Which statement correctly connects the motion of the trumpet with Newton's first law of motion?

According to Newton's first law of motion Trumpet will remain at rest state unless Andrew applies a net force different of zero.

Explanation:

Andrew plays trumpet in the concert band. He holds the instrument still at his side until it is time for him to play. Later, he mover the trumpet up to his mouth and starts to play.

Firstly, the trumpet is at rest stays with zero movements, zero velocity, and zero acceleration. The trumpet remains in this state due to Newton's first law of motion: An object at rest remains at rest and an object in motion stays in motion with the same speed and the same direction unless acted upon by an unbalanced force. As there is no net force acting on the trumpet, it remains in zero velocity.

Secondly, Andrew moves the trumpet. It means Andrew applied force to move the trumpet. Due to it, the body changed from the rest state to the movement state.

Finally, we can conclude that according to Newton's first law of motion Trumpet will remain at rest state unless Andrew applies a net force different of zero.

The first law is An object won't move by itself, and once in motion, it won't stop unless some force acts upon it. With this being said when the trumpet is at his side and he is not holding it will not move not until he lets go of it.
