5. 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)

Question

Responses

Acceleration cannot be predicted based on changes in mass.
Acceleration cannot be predicted based on changes in mass.

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

As rocket mass increases, acceleration increases.

Answer 1

According to Newton’s second law, the relationship between force, mass, and acceleration is given by the formula \( F = ma \), where \( F \) is the force, \( m \) is the mass, and \( a \) is the acceleration. If the force (provided by the motor) remains constant and the mass of the rocket increases, the acceleration will decrease.

Therefore, the correct response is:

As rocket mass increases, acceleration decreases.
