For force, for instance, why can't we just use m x kg without the s-2?
Dory said:Right, so there has to be a defined scale of time in order for it to work, I see. Does it mean if the same m x kg is applied at 5 seconds as opposed to 1 second, the force would be lesser.
Correct?
The s-2 unit, also known as meters per second squared, is used to measure acceleration, which is a crucial component of force. Force is defined as mass times acceleration, so in order to accurately describe and calculate forces, we must use the s-2 unit.
The s-2 unit is not directly related to energy, as energy is measured in joules. However, since force is a component of work (force applied over a distance), which is a form of energy, the s-2 unit indirectly relates to energy.
No, the s-2 unit is a unit of acceleration, while velocity is measured in meters per second. Acceleration refers to the change in velocity over time, so they are related but not the same unit.
Yes, we can use other units, such as newtons (N) or pounds (lbs), to describe force. However, the s-2 unit is the standard unit for measuring acceleration and is often used in scientific calculations for its consistency and precision.
In physics, we use the s-2 unit to describe forces because it is a fundamental unit of measurement that is defined by the International System of Units (SI). Using the s-2 unit allows for a standardized and universal way of communicating and understanding forces in scientific research and experimentation.
