Give an advantage of friction | When a bike stops when you pull the brake |
Give a disadvantage of friction | Friction causes the wearing of moving surfaces in contact |
What is Lubrication? | Lubrication is used to reduce the friction between to surfaces in contact |
Give three characteristics of wieght | It is a force,it is measure in newtons and the weight of an object can change |
Give three characteristics of mass | It is measure in grams or kilograms,it does not have a direction and the mass of an object remains constant |
What is the equation to covert mass into weight? | Weight(in Newtons) = mass in kilograms x 10 |
What is Hooke's law? | It states that the extension of an elastic body(a spring) is directly proportional to the force causing the extension |
