The SI unit of force is:
Joule
Watt
Newton
Pascal
Newton
The SI unit of force is the Newton (N), named after Sir Isaac Newton. It is a derived unit defined as the amount of force required to accelerate a mass of 1┬аkg by 1┬аm/s2.
The SI unit of force is the Newton (N), named after Sir Isaac Newton. It is a derived unit defined as the amount of force required to accelerate a mass of 1┬аkg by 1┬аm/s2.
Think of a Newton as the approximate force needed to lift a medium-sized apple (about 100g) against gravity.
F=m├Чa тАФ Newton's Second Law of Motion
1┬аN=1┬аkgтЛЕm/s2 тАФ Definition of Newton in base units
According to Newton's Second Law of Motion, the force F applied to an object is equal to the product of its mass m and acceleration a. Thus, F=m├Чa. When mass is in kilograms and acceleration is in meters per second squared, the unit of force is defined as the Newton.
The Newton is a derived SI unit.
It is a vector quantity, meaning it has both magnitude and direction.
Force is measured using instruments like spring balances.
Calculating structural loads in engineering.
Determining the gravitational force acting on objects.
Joule (J) is the SI unit of energy or work.
Watt (W) is the SI unit of power (1┬аJ/s).
Pascal (Pa) is the SI unit of pressure (1┬аN/m2).
C is correct тАФ The Newton is defined by the SI system as the unit of force equivalent to 1┬аkgтЛЕm/s2.
Always distinguish between force (F=ma, unit: Newton) and energy (W=Fd, unit: Joule) to avoid confusion in numerical problems.
