Question

match each of newtons laws of motion to the statement it best describes. newtons first law of motion newtons second law of motion newtons third law of motion jayden has to use more force to do a pull - up if he wears a 20 - kilogram weight belt than if he is pulling only his body weight. the pull - up bar pulls up on jayden with the same force that jayden pulls down on the pull - up bar. jayden will remain at rest until he pulls down on the pull - up bar.

Explanation:

Newton's second law ($F = ma$) relates force, mass, and acceleration. Wearing a weight belt increases mass, so more force is needed for the same acceleration (pull - up), which is the second law. Newton's third law states that for every action, there is an equal and opposite reaction. The pull - up bar's upward force on Jayden and Jayden's downward force on the bar are an action - reaction pair, so this is the third law. Newton's first law says 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. Jayden remaining at rest until he pulls on the bar is an example of the first law.

Answer:

Newton's second law of motion: Jayden has to use more force to do a pull - up if he wears a 20 - kilogram weight belt than if he is pulling only his body weight.
Newton's third law of motion: The pull - up bar pulls up on Jayden with the same force that Jayden pulls down on the pull - up bar.
Newton's first law of motion: Jayden will remain at rest until he pulls down on the pull - up bar.
