Question

the same motor is used in rockets with different masses. the rockets have different accelerations. according to newtons second law, how is acceleration expected to change as the rocket mass increases? (1 point) as rocket mass increases, acceleration decreases. acceleration cannot be predicted based on changes in mass. there are no changes in acceleration, as it would depend on the amount of force. as rocket mass increases, acceleration increases.

Explanation:

Newton's second law is \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). If the force \(F\) (from the same motor) is constant, then \(a=\frac{F}{m}\). As \(m\) (mass) increases, since \(F\) is fixed, the value of \(a\) (acceleration) will decrease because it is inversely proportional to \(m\).

Answer:

As rocket mass increases, acceleration decreases.
