What are the 4 types of frictional force?
Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.
What does force and friction depend on?
Generally, the magnitude of the force of friction depends on the roughness of the material. The rougher or bumpier the material, the more friction there will be. The magnitude of the force of friction also depends on the Normal Force. We usually think of the normal force as opposite to weight.
Which type of friction is the weakest?
Rolling friction is the weakest kind of friction. It is the force that resists the motion of an object rolling across a surface.
What causes friction?
Scientists are not completely sure what causes friction; however it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.
Is force of friction?
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
What is friction question answer?
Define friction. Answer: Friction is the force which resists the motion of a body, while moving on a surface. What is meant by sliding friction ?
What is P in friction?
The direction of the frictional force is opposite to the pending relative motion of the surfaces. If the force (P) increases, friction force (F) will also increase, until F Fs (limiting static frictional force). If F = Fs, then the block is in unstable equilibrium and block will move.
What 2 factors affect friction?
Friction is a resistive force, which comes into play when there is a relative motion between two bodies in contact. The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.
How is friction related to force and motion?
A type of friction that occurs when air pushes against a moving object causing it to decelerate. Q. The amount of friction depends on the weight of the objects pressing together. Q. The rougher the surface, the faster an object will travel over the surface.
Are there any multiple choice questions on friction?

Which is the best example of friction in physics?
Explain that friction is a friend or foe with best examples.Please answer this quickly as this is very urgent. Sir pls solve the following. a car is pulling a trailer in a plane.is force applied by car on trailer is equal to applied force by trailer on car? a child’s father pushes the swing to increases the speed of the spring.why?
What happens to friction when a forklift stops pushing?
Once the pallet starts moving, the coefficient of friction drops from its static value to its kinetic value. But the forklift is still pushing with 1650 N of force. Thus we have a nonzero net force. A net force causes acceleration. Acceleration goes with a change in velocity. Once the forklift stops pushing, kinetic friction becomes the net force.
