The reading on a spring scale is equal to the friction force acting on an object because the spring scale measures the normal force exerted by the object on the scale. In the case of an object on a flat surface, the normal force is equal in magnitude but opposite in direction to the gravitational force acting on the object. The friction force, which opposes the motion of the object, is directly proportional to the normal force according to the coefficient of friction between the object and the surface, thus making the reading on the spring scale equal to the friction force.
What else can I help you with?
What causes the change in the spring scale reading?
The change in the spring scale reading is caused by the force applied to the spring. When an external force is applied to an object attached to the spring scale, the spring compresses or stretches, leading to a change in the scale reading which reflects the magnitude of that force.
How is force and friction related?
The Force of friction is equal to the coefficient of friction times the normal force. Since normal force is equal to mass times the acceleration of gravity (9.8 m/s2), the force of friction is directly proportional to the mass.
When an object is pulling across a level surface at a constant velocity what force is the pulling force equal to?
When an object is moving across a level surface at a constant velocity, the pulling force is equal to the force of friction acting in the opposite direction. This force of friction is equal in magnitude and opposite in direction to the pulling force, resulting in a balanced situation where there is no acceleration.
Example of spring force?
An example of spring force is when you compress a spring by applying a force to one end. The spring will exert an equal and opposite force in the opposite direction, trying to return to its original shape. This restoring force is known as spring force.
What is the maximum static friction force that can be exerted on an object?
The maximum static friction force that can be exerted on an object is equal to the coefficient of static friction multiplied by the normal force acting on the object.
Why is reading on the spring scale equal to the friction force in each case?
because the spring scale measures friction..therefore the measure (from the spring scale) is equal to the force needed to do something
What causes the change in the spring scale reading?
The change in the spring scale reading is caused by the force applied to the spring. When an external force is applied to an object attached to the spring scale, the spring compresses or stretches, leading to a change in the scale reading which reflects the magnitude of that force.
When an object is pulled on a level surface at a constant velocity what force is the pulling force equal to?
If there is no friction or anything that can impede the movement off the object, then the force is zero. If there is friction, then the force is equal to that of the friction.
What does the spring scale measure if measured in newtons?
A spring scale measures force in newtons. It works based on Hooke's law, which states that the force applied to a spring is directly proportional to the extension or compression of the spring. The scale calculates the amount of force required to extend or compress the spring.
How is force and friction related?
The Force of friction is equal to the coefficient of friction times the normal force. Since normal force is equal to mass times the acceleration of gravity (9.8 m/s2), the force of friction is directly proportional to the mass.
When an object is pulling across a level surface at a constant velocity what force is the pulling force equal to?
When an object is moving across a level surface at a constant velocity, the pulling force is equal to the force of friction acting in the opposite direction. This force of friction is equal in magnitude and opposite in direction to the pulling force, resulting in a balanced situation where there is no acceleration.
What is friction and what is meant by maximum friction?
Friction is a force that opposes motion. Maximum friction is the?æ force that must be overcome in order for a body to start moving.?æ Maximum friction is equal to the?æ product of normal force and coefficient of the friction.
Is there a force that can go against friction?
No. Friction can only slow an object down. If friction were imparting a force greater than that of the applied forces, then friction in and of itself would actually be causing the object to move, which does not happen.

What is the maximum static friction force that can be exerted on an object?
The maximum static friction force that can be exerted on an object is equal to the coefficient of static friction multiplied by the normal force acting on the object.
When an object is pulled across a level surface at a constant velocity what force is the pulling force equal too?
The pulling force is equal to the force of friction acting in the opposite direction. At constant velocity, the force of friction is equal in magnitude but opposite in direction to the pulling force, resulting in a net force of zero and thus no acceleration.
Can you measure the force of friction?
Yes, the force of friction can be measured using a spring scale. The force required to overcome friction between two surfaces can be determined by measuring the force needed to move an object along those surfaces. The friction force is proportional to the normal force between the two surfaces.
