The standard unit of force (SI) is ____.
Newton
The correct answer is Newton.
We can summarize the units and their corresponding quantities in the table below: Unit Physical Quantity Pascal (Pa) Pressure Newton (N) Force Joule (J) Energy or Work Gray (Gy) Absorbed Radiation Dose Therefore, among the given options, the Newton is the standard SI unit of force. Understanding the definition of the Newton helps solidify why it is the appropriate unit for force in the SI system.
Important Questions from Units, Dimensions and Measurements
According to Newton's second law of motion, force ($F$) is defined as the product of mass ($m$) and acceleration ($a$), i.e., $F=ma$. If an object with a mass of $1 \text{ kg}$ experiences an acceleration of $1 \text{ m/s}^2$, what is the standard SI unit used to quantify this force?
kg m/sec is the unit of
Which of the following instruments is used to measure the radius of wires?
The dimension of linear momentum is identical to that of which of the following expressions?
Power is defined as the rate at which energy is expended or transferred. If the dimensional formula for energy is $ML^2T^{-2}$, what is the dimensional formula of power?
