Physics Ymx ~ Thats the equation of a straight line on the x-y plane. Y a b x c b. Which can also be written as y b mx. Fit the slope and point into the equation. Eg ww qfi 4. Equation from above to match the general experesion for a straight line y mx c. We can see from the red boxes above that. Y mx b y-intercept slope the value of y when x 0 Of course in Physics we dont use x. Displaystyle dx varied depending on context. The slope m of a linear function is the rate of change of the vertical quantity y with respect to the horizontal quantity xIt should be apparent that the slope of this graph is the average price for electricity per kilowatt hour. Indeed lately has been hunted by consumers around us, perhaps one of you. Individuals now are accustomed to using the net in gadgets to see video and image data for inspiration, and according to the title of the post I will talk about about Physics Ymx. Y mx b 2a. Write down the general form of the mathematical equation ie. F M a Clearly the force F the weight of the hanging mass must be plotted on the y axis. Y mx b y-intercept slope the value of y when x 0 Of course in Physics we dont use x. 842015 Y mx b is the equation for a straight line. 3172020 This expresses the equation in the slope-intercept form of a line y mx b. Physics Stack Exchange is a question and answer site for active researchers academics and students of physics. Now that we know the slope m and a point xy we can use this equation to solve for b the y-intercept. It has therefore a unique solution for y which is given by. However at 315 I went off in the wrong direction when I tried to get variable b by itself.
Which can also be written as y b mx. XXX y b m x. So if you plot a graph of KE max against f for a specific metal the gradient of the line would be h and the y-intercept would be the negative of the work function of the metal φ.
Fit the slope and point into the equation.
It has therefore a unique solution for y which is given by. The length of the pendulum were plotted on a graph with logarithmic axes then the slope of the line would equal n and the y-intercept would be equal to the value of log10 k. Displaystyle y- frac a bx- frac c b. Y mx b 2a.
