What else can I help you with?
Why did you pull a sneaker that wasn't moving to test starting friction?
Why do you pull the sneaker at a slow speed for stopping friction?
Which friction force is exerted by the fluids?
The friction force exerted by fluids is typically referred to as viscous drag. This force arises due to the friction between the moving object and the fluid it is moving through. Viscous drag depends on the velocity of the object and the properties of the fluid.
Why is there 10 newtons of force when a student pushes a tree and it does not move?
When a student pushes a tree and it does not move, the force applied by the student (10 newtons in this case) is equal and opposite to the static friction force between the tree and the ground. This static friction force prevents the tree from moving.
Fluid friction acting on an object moving throught the air?
Fluid friction, also known as air resistance, is the force exerted by the air on an object moving through it. This force opposes the motion of the object and increases with the speed of the object. It can affect the object's acceleration and overall motion, leading to a decrease in its speed.
What is Laws of Dynamic friction?
The laws of dynamic friction describe the relationship between the force required to overcome friction between two surfaces in motion and the normal force acting perpendicular to those surfaces. These laws state that the force of friction is proportional to the normal force and is independent of the surface area in contact, while the coefficient of friction relates the force of friction to the normal force.
What forces can slow down a moving object?
Friction, air resistance, and gravitational force can all act to slow down a moving object. Friction occurs when two surfaces rub against each other, air resistance is the force exerted by air on a moving object, and gravitational force can work against the object's motion.
What is the formula for Coefficient of friction?
(Static coefficient of friction) Cf = horizontal force (newtons) required to overcome static resistance / vertical force (newtons) due to objects mass * acceleration due to gravity. Note: Moving friction coefficient is generally less.
A crate remains at rest on a factory floor while you push on it with a horizontal force F How big is the friction force exerted on the crate by the floor?
The friction force exerted on the crate by the floor is equal in magnitude but opposite in direction to the pushing force you apply to the crate. If the crate is not moving, the friction force is static friction, and it adjusts its magnitude to exactly match the applied force to keep the crate at rest.
What is the friction between moving particles called?
The friction between moving particles is called friction.
Will a ball slow down on a level surface without friction?
An object in motion will stay in motion unless and until acted upon by a force like friction. So absent ALL friction, no the ball will not slow. This is part of the laws of Thermodynamics. However, if there is air friction in play, with a long course of time(of course which depends on the velocity with which the ball is moving), the pressure exerted in opposite direction by the ball, at one fine movement should make the ball stop. If considered in vacuum, then again as per Newtons laws, the ball should not stop as there would be no action by any external agency.
'A car with a mass of 1200 kilograms is moving around a circular curve at a uniform velocity of 20 meters per second The centripetal force on the car is 6000 newtons What is the radius of the curve'?
32meters
Why is kinetic friction less than the limiting friction?
By my understanding, this is due to the fact that it is easier to keep a moving object in motion than it is to accelerate it from a resting position. When a force is exerted on a stationary object, acceleration relies on that force alone. However, with a moving body, the momentum of the object reduces the force needed to overcome friction.
