Question

1. how does friction affect mass and speed? (1 point)

an increase in fiction does not change the mass but it decreases the speed.

if friction increases, there is will increase both the mass and speed.

friction will not affect mass or speed.

if friction increases, both mass and speed will decrease.

Explanation:

Mass is an inherent property of an object and is not affected by friction. Friction is a force that opposes motion. According to Newton's second law \(F = ma\) (where \(F\) is the net force, \(m\) is mass, and \(a\) is acceleration), when friction (\(F_f\)) acts on an object, if the applied force \(F_{app}\) is constant, the net force \(F_{net}=F_{app}-F_f\). As \(F_f\) increases, \(F_{net}\) decreases. Since \(a = \frac{F_{net}}{m}\), a decrease in \(F_{net}\) (with \(m\) constant) leads to a decrease in acceleration. If acceleration is negative (opposing the direction of motion), the speed of the object will decrease over time.

Answer:

An increase in friction does not change the mass but it decreases the speed.
