If i am standing on bathroom scales and i lift a weight, what will it do to the reading on the scales?
I assume that lifting the weight will involve a force from my arm on to the weight, and an equal and opposite force will then push back, causing be to weigh more?
Point 1 Does that mean that the non driven wheels, do not experience any static friction with the road?
Point 2 Yes, the dynamic friction between all the moving parts, from the engine to the axle. That is countering the driving force of the car
I think i can answer my own question, the static friction between the wheel and the road acts in the direction of travel. The dynamic friction between the wheel and the car acts opposite the direction of travel. This is the friction shown in the free body diagram of a car moving.
When a car moves forward, the wheel turns it exerts a force on the road in the opposite direction of travel, and friction counter acts it. the wheel turns and the car moves forward This implies that friction on the wheel is acting in the direction of the car moving. Though I thought that...
