What else can I help you with?
Suppose work input is 25 J and the output distance is 10 m. Factoring in the effect of friction which must be true about output force?
Considering the work input and output distance, to account for the effect of friction, the output force must be greater than the input force due to the work lost to friction. This means that the output force required to move the object the specified distance against friction will be higher than what would be calculated based solely on the given work input and output distance.
Does speed affect the friction between a road and a skidding tire?
Speed does not affect the force of friction.
What 3 factors affect the force of friction?
The three factors that affect the force of friction are the weight of the object, the roughness of the surfaces in contact, and the normal force pressing the surfaces together.
What properties affect the force of friction?
The nature of the surface. A measure of this is the coefficient of friction.
If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
What two factors affect the force of friction?
Inertia
What are the factors which affect the force of friction?
Friction equals the coefficient of friction times the normal force. Friction increases as the roughness of the materials increases. It also increases as the force pushing the materials together increases.
What factor affect the mechanical advantage of simple machine?
friction affects the M.A in a simple machine.
What two variables affect friction?
The two variables that affect friction are the surface roughness of the materials in contact and the force pressing the surfaces together. As the roughness increases or the force increases, friction typically increases as well.
Does surface type affect the force of friction?
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
What Two factors that affect the magnitude of friction?
The two factors that affect the magnitude of friction are the nature of the surfaces in contact and the normal force pressing the surfaces together. Friction is stronger when the surfaces are rough and when the normal force increases.
Does the nature in contact influence friction force?
Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.
