What is the relationship between mass and force of sliding friction?
The force of sliding friction is directly proportional to the mass of the object experiencing the friction. As the mass increases, the force of sliding friction also increases. This relationship is described by the equation: force of friction = coefficient of friction * normal force, where the normal force is equal to the weight of the object (mass * acceleration due to gravity).
What is the difference between normal reaction and abnormal reaction?
A normal reaction is a response that is considered typical or expected in a given situation. An abnormal reaction, on the other hand, is a response that deviates from what is considered typical or expected, and may indicate a problem or issue that needs to be addressed.
How to calculate the normal force acting on an object held against a wall given mass and force?
The normal force is equal in magnitude but opposite in direction to the force applied against the wall. If the object is held against the wall with a force, then the normal force acting on the object will be equal in magnitude to that force. If the mass of the object is given, you can calculate the force needed to hold it against the wall using Newton's second law (F = ma).
What is a normal reaction for the patellar reflex?
knee jerk
What is the visual reaction time of a normal person?
The average visual reaction time of a normal person is about 200-250 milliseconds. This is the time it takes for a person to see a stimulus and react to it. Factors like age, fatigue, and distractions can affect reaction time.
How do friction and gravity relate?
The magnitude of friction is proportional to the magnitude of the normal force which is proportional to the magnitude of gravity(The magnitude of the normal force is indirectly proportional to the magnitude of gravity.). The magnitude of the normal force, N, compared to gravity, G, on angle z, is: N=cos(z)*G On a flat surface. N=G The coefficient of friction, whether static or kinetic, f is therefore: N=cos(z)*G*f
What two factors that affect the amount of friction between two surfaces?
The magnitude of the frictional force is directly proprotional to the normal reaction between the two surfaces.(2)Magnitude of the frictional force is independent of shape and area of the surfaces
State laws of limiting friction?
1. the direction of force of friction is always opposite to the direction of motion.. 2. the magnitude of limiting friction depends upon the nature and state of polish of the two surfaces in contact and acts tangentially to the interface between them.. 3. the magnitude of limiting friction 'F' is directly proportional to normal reaction 'R' between the two surfaces in contact.. 4. the magnitude of limiting friction is independent of area and shape of surfaces in contact as long as the normal reaction remains the same..
Why does weight affect frictional force?
Weight affects frictional force because friction is a force that opposes motion and is directly proportional to the normal force acting on the object. The normal force acting on an object is influenced by its weight, so an increase in weight results in a greater normal force and therefore a greater frictional force.
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.
If the mean of a normal distribution is negative what is the varience?
The variance is always positive. The variance is not directly related to the sign (nor magnitude) of the mean.
What relationship exists between the static frictional force and the normal force of an object?
The static frictional force is directly proportional to the normal force acting on an object. As the normal force increases, the maximum static frictional force that can be exerted on the object also increases.
Does magnitude of normal force always equal the weight of the object?
No, not always directly opposite. The normal force is always perpendicular to the surface. So for a flat ground it will be directly opposite gravity or Weight.If you had an object on a ramp the normal force would be a diagonal line that is perpendicular with the ramp.
What is the relationship between mass and force of sliding friction?
The force of sliding friction is directly proportional to the mass of the object experiencing the friction. As the mass increases, the force of sliding friction also increases. This relationship is described by the equation: force of friction = coefficient of friction * normal force, where the normal force is equal to the weight of the object (mass * acceleration due to gravity).
How does the magnitude of the normal force compare to the weight of the box?
The magnitude of the normal force is equal to the weight of the box when the box is at rest on a flat surface.
Why doesn't normal force Fn depend on the cup material used?
The normal force depends on the weight of the object pressing down on the cup, not the material of the cup itself. The material might affect how the cup distributes the normal force, but it doesn't directly influence the magnitude of the normal force.
What is the difference between normal reaction and abnormal reaction?
A normal reaction is a response that is considered typical or expected in a given situation. An abnormal reaction, on the other hand, is a response that deviates from what is considered typical or expected, and may indicate a problem or issue that needs to be addressed.
