Is a spring balance a scale?
A spring balance (or newton meter) is a type of weighing scale. They are commonly used to measure the force exerted on an object.
What are the advantages and disadvantages of using a spring scale to measure weight?
What are the advantages and disadvantages of using a spring scale to measure weight? For this lab in particular, a disadvantage is that some of these objects are not made to hook onto a spring scale, thus skewing the results. An advantage would be the accuracy of a spring scale, when used correctly.
Can spring balance be used to measure mass?
Spring balance is a mechanical device used for measuring the weight or force of an object by opposing the force of gravity with the force of an extended spring. Note – Spring balance measures the weight of an object but not used for mass.
How is spring balance used to measure weight?
Spring balances provide a method of mass measurement that is both simple and cheap. The mass is hung on the end of a spring and the deflection of the spring due to the downwards gravitational force on the mass is measured against a scale.
What is a spring balance used to measure?
Answer: Spring balance is used to determine the force acting on the object (weight). Spring balance works on the principle of Hooke’s law.
What are the sources of uncertainty when using a ruler?
Determine uncertainty There are at least two sources of uncertainty in your distance measurement: uncertainty caused by your inability to see exactly where on the ruler your fingers catch the ruler, and uncertainty caused by random variation in each trial. Let’s find each one and compare them.
Where does the force causing this vertical acceleration come?
A projectile is an object upon which the only force is gravity. Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity.
Why is spring balance used to measure weight?
A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring.
What is the purpose of a spring scale?
They are also common in science education as basic accelerators. They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness. A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring.
How is measurement uncertainty evaluated?
Standard measurement uncertainty (SD) divided by the absolute value of the measured quantity value. CV = SD/x or SD/mean value. Standard measurement uncertainty that is obtained using the individual standard measurement uncertainties associated with the input quantities in a measurement model.
