Why is it important to zero a spring scale?
Zeroing a spring scale ensures that it reads accurately by accounting for any variations or offsets in its baseline measurement. By zeroing the scale before each use, you can obtain precise weight measurements and minimize errors in your readings.
What instrument measures mass and volume?
A ruler and a spring scaleMass- Triple Beam BalanceVolume- Graduated Cylinder
What can you use to measure the mass of two objects?
This comparison is very simple: measure the mass with a balance.
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 the reading on the spring scale equal to the friction force in each case?
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 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.
Why is it important to zero a spring scale?
Zeroing a spring scale ensures that it reads accurately by accounting for any variations or offsets in its baseline measurement. By zeroing the scale before each use, you can obtain precise weight measurements and minimize errors in your readings.
Indicate the scale of measure for each value on the y-axis?
Yes, you should!

What is the scale used to measure minerals hardness?
The scale used to measure mineral hardness is called the Mohs scale. It ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch each other.
What is the scale used to measure the hardness of a mineral?
The scale used to measure the hardness of a mineral is called the Mohs scale. It ranges from 1 (softest) to 10 (hardest), with each number representing a different level of hardness.
