Which type of friction is the hardest to overcome?
Which type of friction is the hardest to overcome? Static friction Do smooth tires have more friction? Under dry conditions on paved roads, a smooth tire gives better traction than a grooved or patterned tread because a larger area of contact is available to develop the frictional forces. These values represent a compromise between the […]
What causes a solution to be conductive?
What causes a solution to be conductive? When a solution conducts electricity, the charge is carried by ions moving through the solution. Ions are atoms or small groups of atoms that have an electrical charge. Some ions have a negative charge and some have a positive charge. Pure water contains very few ions, so it […]
What is the relationship between weight and mass?
