Why is the reading on the spring scale equal to the friction force in each case?
A scale is a force indicator. The reading on a scale is simply telling you what force is being applied. If you try dragging an object across the floor using a spring scale, you are applying a force to the spring scale which is applying a force to the object. The spring scale cannot put more force on the object than you are putting on the scale, and it has to put all of the force that you put on it on the object you are pulling. The only other force on the object besides your pulling force is friction. If the object is traveling at a constant velocity, the forces on it are equal. That means that your pulling force has to equal the force of friction. The scale that you are using will read the amount of force you are putting on the object which will tell you how much friction is pulling backwards on the object because these forces are equal strengths.
When you stand on a bathroom scale what does it display the earth exerting on you?
Newer scales like digital and spring scales, measure the force your body exerts on the pad you're standing on, which is your weight. The scale then divides your weight by gravity to give you your mass.
How do you make an improvised spring scale?
Spring Scale Materials and Equipment To do this you will need the following materials and equipment: * Several springs with different lengths, diameters, and stiffness * Weights to hang from springs, here are some tips: ** You can use metal weights, or hang a container from the spring and fill it with glass beads, water, or sand ** The appropriate weight to be used with each spring depends on the stiffness of spring, you'll have to use your best judgment * Sturdy support from which to hang the springs, for example: ** Wood ** Sturdy cup hook ** Clamp ** Screw the cup hook into one end of the piece of wood ** Clamp the other end of the wood to a table or workbench ** Hang the spring from the cup hook ** The clamp and wood will both need to be strong enough to support the weights you intend to hang from your springs * Kitchen scale for measuring actual mass of weights used * Metric ruler Procedure # Do your background research so that you are knowledgeable about the terms, concepts, and questions, above. # For each spring, do the following steps: ## Hang the spring from a sturdily-mounted hook. ## Measure the length of the spring with no weight hanging from it. Always measure between the same two points on the spring (you may even want to mark them). ## Hang a weight from the spring, and wait for it to settle. ## Again measure the length of the spring. ## Measure the mass of the weight, using the kitchen scale. ## Repeat for a series of different weights. ## Remove the weight from the spring, and check to make sure that the spring returns to its initial length. ## Do at least three trials for each spring. # Keep track of your results in a table like this one: Weight(g) Length of spring(cm) Average(cm) Change in length(cm) Trial #1 Trial #2 Trial #3 0 - 5 10 20 40 0 - # To calculate the change in length, subtract the average length of the spring with no weight (0 g) from the averaged measured length for each of the other weights. # For each spring, make a graph of the change in length of the spring (in cm, y-axis) vs. the mass of the weight hanging from the spring (in g, x-axis). # More advanced students should graph the change in length of the spring (in cm, y-axis) vs. the force on the spring (in newtons, x-axis). The force on the spring in newtons can be obtained by multiplying the mass (in kg) by the acceleration due to gravity: 9.8 m/s2. Remember that to convert g to kg, you have to divide by 1000.
Why is a triple-beam balance used to measure each object instead of a scale?
Actually, its not. The scale is used almost as much as the triple beam balance. The thing is that a scale can be made as big as it can get, but a triple beam balance can't. On the other hand, the triple beam is more precise and can measure more small objects.
If the length of a spring is halved the stiffness becomes?
If spring is cut into two parts, each spring will have it's stiffness doubled. For n parts, stiffness of each part will be nk
What do a pan balance and the spring scale each measure?
Weight
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 scale is used to measure magnitue?
The Richter scale. The magnitude increases by powers of 10 for each increment.

Indicate the scale of measure for each value on the y-axis?
Yes, you should!
What is nonlinear scale?
Nonlinear scaling is a scaling where the difference between each major unit of measure is not the same. For example, see logarithmic scale.

What is the scale to measure earthquake?
Seismometers are used to measure earthquakes waves, this help show the different arrival time between waves. A Richter Scale is used to measure earthquakes strengh, each number is 31 times more powerful than the last. There is no official set number, but no earthquake has hit 10 on the scale.
What to use to measure distance on a map?
If you look at the bottom of the map, there should be a scale. Take a ruler, measure the distance for each measurement, and convert to what you need

What do you use to measure the volume of a solid?
A weighing scale! you can get metric and imperial measured scales, some are electrical and some spring balanced. The electrical ones are more precise, and can be easily tared, and easily changed to many different settings.
How do you mesure mass?
The fact of an object having mass has two noticeable effects: inertia, and gravitational attraction. The easiest way to measure mass is probably through its weight. For example, a spring scale technically measures force, but is already calibrated (marked) for mass. A balance scale compares the mass with another mass - but once again, using the weight of each mass.
