A force meter is a device comprising a hook and spring that measures force. The standard international unit of force is the newton.Know More
Force is a push or pull measured in newtons, named after the scientist Isaac Newton. Force can alter the shape of an object. It can also change the direction of motion of an object, or increase or decrease its speed.
It is possible to measure force using a device called a force meter. The front of the force meter features markings that indicate the number of newtons. Running through the center of the device is a measuring section on a spring with a metal hook on the end.
Hanging an object on the hook of a force meter results in the spring stretching due to the pull of the force. If the object exerts a large amount of force, then the spring stretches a long distance. An experimenter can read the measurement of force from the markings on the meter.
There are effectively two types of forces. Contact forces result in a direct physical interaction, such as air resistance, friction or tension. Other forces act at a distance in a non-physical interaction, such as gravity or magnetic forces.Learn more in Motion & Mechanics
Effort force is the force that moves an object over a distance by overcoming a resistance force. The formula for force is force = mass x acceleration or F = MA and is measured in newtons.Full Answer >
Inertia is not a force. Scientist Isaac Newton defined it as the property of a massive body that keeps it still if it is already still, or keeps it in motion if it is already in motion. Inertia is inextricably tied to mass, although it is a distinct quantity.Full Answer >
For an object with unchanging mass, force equals mass times acceleration. This is abbreviated as f = ma. Force is a push/pull on an object resulting from interactions with another object. Having a magnitude and a direction makes force a vector quantity.Full Answer >
A mechanical force involves contact with another object. Mechanical forces are distinguished from the four natural forces of electromagnetism, the strong nuclear force, the weak nuclear force and gravity. While each of the four natural forces do not require a physical connection, mechanical forces must travel through a medium.Full Answer >
