this question came up in my work, and i don't remember reading about it in my book. can you tell me what it is asking for, and how to do it..
if the change in position delta x is related to velocity v(with units of m/s) in the equation delta x=Av, the constant A has which dimensions?
i have no clue how to even start figuring this out
position units = velocity * time units
meters = (meters/second) * seconds
im still kinda confused...would the answer be m/s^2...?
delta position=velocity*deltatime
Units: meters=m/s * sec
So would not A be seconds?
yes, thnks alot
The question is asking about the dimensions of the constant A in the equation delta x = Av, where delta x represents the change in position and v represents velocity with units of meters per second (m/s). To determine the dimensions of the constant A, we need to analyze the dimensions of both sides of the equation.
The dimensions of delta x are meters (m), as it represents a change in position. The dimensions of v are meters per second (m/s), as it represents velocity.
Since both sides of the equation must have the same dimensions for it to be valid, we need to find the dimensions of the constant A such that it matches the dimensions of delta x divided by v.
To do this, we divide both sides of the equation by v:
delta x / v = Av / v
On the left side, delta x / v represents the ratio of the change in position to velocity, which is a dimensionless quantity.
On the right side, Av / v simplifies to just A since v/v equals 1.
Therefore, we can conclude that the dimensions of the constant A must also be dimensionless.
In summary, the constant A in the equation delta x = Av has dimensionless dimensions.
