Force is measured in newtons (N). It represents the force of 1 kilogram of mass being accelerated one meter per second per second.
Because over a certain limited range, a carefully manufactured and very expensive spring will stretch exactly in proportion to the magnitude of the force that's causing it to stretch, and the magnitude of the force can be accurately determined simply by observing and measuring the length of the stretch.
the measurer
The Stanley TLM 300 Laser Distance Measurer is specified to measurewithin 1/16 inch of the true distance at 100-ft.
Your feet exert a force on the ground so in return the ground exerts a force on your feet.
Hargen the Measurer was created in 1977.
A laser measurer can be purchased from a wide variety of places. A laser measurer can easily be bought at a local electronics store or hardware store. It can also be bought from auction sites.

A spaghetti measurer is used to determine the amount of spaghetti for one serving. Depending on the size of your spaghetti measurer, I have seen up to four servings, you would be able to know how much spaghetti to cook for a certain number of people.

The reason for serial of light spots appearing on the measuring scale is due to an effect known as parallax error. Parallax error occurs when the measurer's eye is not directly over the scale, causing the light spots to appear in a series. This can be caused by the measurer moving their head or body while taking a measurement, or the measurer not being in the correct position to take an accurate measurement. The light spots will appear in a series because the measurer's eye is seeing the measurer's scale from different angles. As the measurer moves, the angles change and the light spots appear in a series. This can lead to inaccurate measurements, as the measurer may not be able to accurately read the scale due to the parallax error. To remedy this, the measurer should make sure they are in the correct position before taking a measurement, and should not move while taking a measurement.
