What would be the unit if the variable appears in mathematical power in exponential terms. For example, e^(alpha * t) is on side of the equation. Should the its dimensions always be nullified by the constant that comes with it?

@garrisonturner5670 Жыл бұрын

When a variable appears as the argument of an exponential, trigonometric, logarithmic, or hyperbolic trig function, the overall argument needs to be dimensionless, so any constant that appears in the argument needs to cancel the dimensions of the variable out. So, in your example, e^(alpha*t), alpha would need units of inverse seconds (like frequency or angular frequency.)

In most of the introductory examples, yes, because most of the equations in the next section are kinematic and thus use position/displacement, velocity, and acceleration.

How do i analyse SINCOSTAN?

@garrisonturner5670 Жыл бұрын

The arguments of trig functions need to be unit-less. As a result, if you have something like y=A*sin(wt) where w is the angular frequency and t is time, then the units of w and t need to cancel out. Since t will be (in SU units) seconds, w needs to be (seconds)^-1 or radians per second.

@garrisonturner5670 Жыл бұрын

Generally in physics, especially related to motion, yes, x, y, and z represent spatial coordinates and therefore carry dimensions of length.

@garrisonturner5670 2 жыл бұрын

Because it’s better than adding a T^3… just kidding 😆. It’s because acceleration has units of distance per time-squared.

Sure it is. It is also a useful conversion factor as well. It's not an equation in the algebraic sense with multiple variables, but it is an equation demonstrating an equivalency.

Acceleration is L/T and not L/T^2 if am not mistaking sir

@garrisonturner5670 2 жыл бұрын

Speed/velocity has units of L/T. Speedometers on cars are either miles per hour here in the US or km per hour in most other places. That is length per time. Acceleration is the rate at which velocity changes with respect to time, or length per time, per time, or L/T^2.

@garrisonturner5670 2 жыл бұрын

@@VH33GOAL8 www.csun.edu/science/ref/measurement/units/units.pdf See the reference sheet above. Speed/velocity units are those of distance/time, while acceleration is how that changes with time. I wouldn’t normally argue a point like this, but this is an educational channel mainly for college students.
