That depends on the exact circumstances. Solid friction hardly depends on the speed at all. In fluid friction, the situation is more complicated. Usually there is some range of speeds for which friction is more or less proportional to speed; at higher speeds, the force of friction may even become proportional to the square of the speed.
Yes Friction=Reaction force x COF Reaction force = mass x gravity So Friction=mass x gravity x COF ^ Change the mass, change the friction
The force on a body determines its acceleration, speed depends on how long the acceleration lasts. Wind resistance and road friction (or other mechanical drag) will affect the power required to maintain a certain speed.
Friction has no effect whatsoever on the law. But if friction is present, then the law can't be demonstrated, because the moving object always has an external force acting on it.
Obviously it does but it depends, the more friction the surface produces the slower the ball will go. Also it depends on how you are going to roll the ball, using a ramp or by hands. But using a ramp would be better because when you use your hands to roll the ball, each time you roll it will slightly be different like the pressure. (;
If the speed is constant, then the group of forces acting on the object is balanced. So the portion of the force acting in the direction of the motion must be equal and opposite to the force of friction.
Speed does not affect the force of friction.
Friction can affect an object's speed by reducing it over time, as it acts in the opposite direction to the object's motion. However, friction does not directly affect an object's velocity which is a vector quantity that includes both speed and direction.
Friction is a force that opposes motion, so it can slow down an object and affect its speed. In the context of motion and velocity, higher friction can decrease speed, while lower friction can increase speed.
Friction tends to slow down an object's speed by opposing its motion. It transforms the kinetic energy of the object into heat, which dissipates into the surroundings. The greater the friction, the greater the decrease in speed.
Increasing speed does not directly affect the coefficient of friction between two surfaces. The coefficient of friction is a property determined by the nature of the surfaces in contact and remains constant regardless of speed, as long as the other conditions (such as surface roughness and temperature) remain the same.
Friction and Gravitational forces
No. The speed of the object does not affect the amount of friction between an object and the surface. Friction is affected by the types of surfaces in contact, smoother surfaces produce less friction, and the weight of the object moving horizontally affects the resistance relative to the two surfaces in contact. Greater weight causes greater resistance.
Ff = μs Fn
No, increasing speed does not directly increase friction. Friction is primarily influenced by the nature of the surfaces in contact and the force pressing them together. However, increasing speed can sometimes generate more heat due to friction, which could in turn affect the friction between surfaces.
The two types of friction that affect a mousetrap car are rolling friction, which occurs between the wheels and the surface of the ground, and sliding friction, which occurs between the axles and the wheels. Both types of friction can reduce the overall efficiency and speed of the mousetrap car.
Factors that do not contribute to friction include the speed of an object and the surface area of the object in contact with the surface. Friction is primarily influenced by the nature of the surfaces in contact and the force pressing the surfaces together. Additionally, the temperature of the surfaces and the lubrication present can also affect friction.
Satellites in a low orbit, however, are slowed by friction with Earth's atmosphere.
