Question

how does changing mass impact the motion of an object? select the correct answer. it changes the size of the object. it causes objects to be stationary. it causes objects to move less. it changes the amount of force of the object.

Explanation:

According to Newton's second law \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). When the force \(F\) is constant, if the mass \(m\) increases, the acceleration \(a=\frac{F}{m}\) decreases. A lower acceleration means the object changes its motion (velocity) less easily, so it moves less (in terms of how its velocity changes). Changing mass does not directly change the size of the object (size is related to volume, not mass in a direct motion - impact sense). Mass alone doesn't cause objects to be stationary (an object can be stationary due to balanced forces, not just mass). Mass is not the same as force (\(F = ma\), mass \(m\) and force \(F\) are different quantities).

Answer:

It causes objects to move less.
