Does speed affect the friction between a road and a skidding tire?
Speed does not affect the force of friction.
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.
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.
How does friction affect output force?
Simply put, friction reduces output force. The more friction there is, the less effectively power will be delivered, and this results in reduced output force.
What two factors affect the force of friction?
Inertia
How does friction affect the net force on an object?
Friction usually reduces the net force and the resulting acceleration.
Does the mass of an object affect friction-?
Yes Friction=Reaction force x COF Reaction force = mass x gravity So Friction=mass x gravity x COF ^ Change the mass, change the friction
What are two factors that affect tha friction force between two surfaces?
The coeffient of friction. The force holding the 2 surfaces together.
How does friction affect movement of object?
Friction provides a force, and therefore an acceleration, in the opposite direction of motion.
Investigate-how friction increases with increase of size of an object?
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on the force of friction.
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 is the Physical concept of Force Friction and Mass?
The mass of an object is constant. The force of friction is a force that resists motion. When an object moves on a surface, the force of friction opposes the motion. Depending on the properties of the surface, the force of friction will change. This difference in frictional properties is demonstrated by 'mu' a greek symbol. Force of friction = mu x Force of gravity = mu x mass x acceleration due to gravity.Therefore, as the mass of an object increases, so does the force of friction that acts upon it while in motion. mu is a constant for a specific surface, so it is a value you have to be given in some cases in order to calculate the force of friction. Comparing ice and ashphalt, ice would have a lower friction coefficient, mu, than ashphalt would and therefore, the force of friction on any given mass moved on either surface would be greater on an ashphalt surface.
