Question

The same motor is used in rockets with different masses. The rockets have different accelerations. According to Newton’s second law, how is acceleration expected to change as the rocket mass increases? (1 point)
Responses

As rocket mass increases, acceleration increases.
As rocket mass increases, acceleration increases.

There are no changes in acceleration, as it would depend on the amount of force.

As rocket mass increases, acceleration decreases.
As rocket mass increases, acceleration decreases.

Acceleration cannot be predicted based on changes in mass.

Answer 1

As rocket mass increases, acceleration decreases.

Reason: Newton’s second law gives a = F/m. With the same motor (same force), a is inversely proportional to mass.
