Admin What forces act on a spring scale?
In the example of a spring scale, gravity is pulling the object down, but tension in the spring or string is pulling the object up! Since the object is stationary or STATIC, the NET FORCE must be equal to zero. An object that is static is said to be in EQUILIBRIUM.
What is the force of a mass on a spring?
In this case the force can be calculated as F=-kx, where F is the restoring force, k is the force constant, and x is the displacement. The motion of a mass on a spring can be described as Simple Harmonic Motion (SHM): oscillatory motion that follows Hooke’s Law.
What is the force pulling on a mass hanging from a spring scale?
The object hanging by the spring is acted on by two forces. The gravitational force pulls its down while the spring resists this. The force exerted by spring is given by Hooke’s law as follows Fs=−k⋅x where k is referred to as Hooke’s constant and x is the displacement.Substituting for values we have Fs=−3⋅12=−36N.
Are the forces that act on a spring scale equal and opposite?
Scales read the magnitude of one of the two forces acting on them, the force they exert on the thing they are attached to. By Newton’s third law the action and reaction forces are equal and opposite. Thus, these forces always have the same magnitude and so the scales always read the same value.
What is an example of spring force?
When you jump on a trampoline, your body weight forces the trampoline downward, which further creates pressure in springs, generating a counterforce stored in springs that throws you upward.
When a mass was hanging from the spring how many forces acted on the spring?
two forces
For a vertically hanging spring-mass there are two forces acting on the mass as it oscillates: the force from the spring pulling up or pushing down, and the force from the Earth always pulling down.
What is spring force with example?
When a metal spring is stretched or compressed, it is displaced from its equilibrium position. As a result, it experiences a restoring force that tends to retract the spring back to its original position. This force is called the spring force. It is a contact force that can be found in elastic materials.
