which of the following is a unit force
Answers
Answer: This may help you
Explanation:
The standard unit of force is the newton (N), equal to kg ⋅ m/s 2. Force is one of two quantities of physics that affect the motion of an object, the other being mass.
Apart from that, there are few other ways we can express the unit of measurement of force. Internationally, many prefer to use a single system called SI unit for measuring force. The SI unit recognized for measurement of force is Newton.
The formula for force states that force is equal to mass multiplied by acceleration. So, if you know mass and acceleration, just multiply them together and now you know the force! The units for acceleration are meters per second squared ( m/s2), and the units for mass are kilograms (kg).
Unit of force is d. Newton (N).
What is Force?
- Force is the external push or pull exerted on or by a body.
- It is given as: F=ma where m is the mass of body and a is the acceleration of the body.
There are three laws of motion that define and describe force.
First law of motion: 'Any object will remain in motion or stay at rest unless and until an external push or pull is applied to it.'
Second law of motion: It defines force. 'Force is defined as rate of change in momentum'.
Third law of motion: It gives direction of force. 'Every force of action will have a reaction which is equal in magnitude and opposite in direction'.
