Question

Compare mass, speed, and friction. In three to five sentences, explain how each term is related and how they influence one another as each one is changed (i.e., when friction/mass/speed is increased or decreased, what happens to the other two if they remain the same?).

Mass, speed, and friction are all interrelated physical quantities that influence each other. Mass is a measure of the amount of matter in an object and is independent of speed or friction. However, when mass is increased, it requires more force to accelerate the object to a given speed, resulting in a decrease in speed if the force remains the same. Additionally, an increase in mass results in an increase in frictional forces, which act in the opposite direction of motion, therefore decreasing speed.

On the other hand, when speed is increased, the frictional forces also increase because the relative motion between the object and its surrounding medium is higher. This increased friction can lead to a decrease in speed unless an equal or greater force is applied. Furthermore, an increase in speed does not directly affect the mass of an object.

Lastly, friction depends on the nature of the surfaces in contact and the force pressing them together but is independent of mass or speed. However, the magnitude of friction increases as either mass or speed increases. This means that when friction increases, it can cause a decrease in speed if the force applied remains the same. Similarly, an increase in friction due to a change in surfaces or force pressing them together can make it harder to accelerate an object, resulting in a decrease in speed or requiring a greater force to maintain the same speed.
