What does frictional force do?
Frictional force acts to oppose the motion of an object in contact with a surface. It is caused by the interaction between the surfaces of the object and the surface it is sliding or resting on. This force can either help to prevent sliding (static friction) or resist the motion of sliding (kinetic friction).
What kind of frictional force is acted upon smooth surface?
If it is perfectly smooth then only sliding friction.
What is the relationship between the keyword block and friction in the context of physics?
In physics, the keyword block is a term used to describe an object that is in contact with a surface and experiencing friction. Friction is the force that opposes the motion of the block when it is trying to move across the surface. The relationship between the keyword block and friction is that the frictional force acts on the block to prevent it from sliding or moving easily on the surface.
Is it true that frictional force on a sliding body on a plane is always directed at the angle of friction to the normal?
The frictional force on a sliding body on a plane will be acting parallel to the plane against the motion of the body. But the magnitude of the (kinetic) friction force is proportional to the weight component normal to the plane. The weight component parallel to the plane is the force that tends to slide the body down the inclined plane. When the sliding body has acquire steady velocity, the friction force is equal to the body's sliding force.
What is critical acceleration?
Critical acceleration is the minimum acceleration required to cause an object to start moving or sliding on a surface. It is the point at which the frictional force between the object and the surface is overcome by the applied force.
What is the gripping power bewtween vehicle tires and roadway surface?
Traction
What is the relationship between contact force and friction?
Contact force is the force exerted between two surfaces in contact with each other. Friction is the force that resists the motion of an object sliding or rolling over a surface. Contact force contributes to the frictional force between two objects - the greater the contact force, the greater the frictional force.
How can you show that frictional force depends on nature of surface in contact?
You can demonstrate that frictional force depends on the nature of the surfaces in contact by conducting an experiment where you measure the frictional force between different surfaces. By varying the types of surfaces (e.g., smooth versus rough), you can observe how the frictional force changes accordingly. The coefficient of friction, which quantifies this relationship, will be different for each pair of surfaces, highlighting the influence of surface nature on frictional force.
Does the frictional force depend on the area of surface contact?
No, the frictional force does not depend on the area of surface contact. It is primarily determined by the nature of the surfaces in contact and the normal force pressing the surfaces together. The coefficient of friction between the surfaces also plays a role in determining the magnitude of the frictional force.
What is the equation for sliding friction?
fk = uk*N Where fk = force of kinetic (sliding) friction uk = kinetic frictional coefficient (dependent on 2 materials sliding past each other) N = normal force (force being exerted perpendicular to the surface across which the object is sliding)
What is the force that opposes the sliding of two surfaces that are in contact with each other?
kinetic frictionA second opinion:Kinetic friction is the resistance to sliding motion when they're already moving.The beginning of sliding motion is resisted by static friction.
How mass related with friction and by which experiment it is prove that frictional force dirctly proportional to normal reaction?
The frictional force is directly proportional to the normal reaction force, which is the force perpendicular to the contact surface. This relationship is proven through the observation in experiments such as the classic block on an inclined plane experiment, or by analyzing the motion of objects on a surface where friction is the only significant force acting. The coefficient of friction is a ratio that quantifies this relationship between the normal force and frictional force.
