Which physical quantity has the same base units as energy? SHOW ALL WORKING OUT!
A:Moment
B:Momentum
C:force
D:pressure
To determine the physical quantity that has the same base units as energy, we need to understand the base units of energy and compare them to the base units of the given options.
The base unit of energy in the International System of Units (SI) is the Joule (J). The Joule is defined as the amount of energy transferred when a force of one Newton (N) is applied to an object and moved through a distance of one meter (m).
Now let's analyze the base units of the given options:
A: Moment
The base unit of moment is Newton-meter (N⋅m), which is derived from the product of force and distance. Therefore, the base units of moment are different from energy.
B: Momentum
The base unit of momentum is also Newton-second (N⋅s), which is derived from the product of force and time. Hence, the base units of momentum are different from energy.
C: Force
The base unit of force is Newton (N), but it is not directly equivalent to energy. However, force is related to energy through work since work is the product of force and distance.
D: Pressure
The base unit of pressure is Pascal (Pa), which is derived from the division of force by area. Pressure is not directly equivalent to energy.
Based on our analysis, none of the options listed (A: Moment, B: Momentum, C: Force, D: Pressure) have the same base units as energy. Energy is represented by the base unit Joule (J), which is the product of force and distance.
Therefore, the correct answer is: None of the given options.
