Question

Pre-Lab Quiz for Experiment 4, Physics 210L Equation 4.4 is a statement of Newton's Second Law and is linear (ie., the equation of a straight line): Force x 1/(mt M) (4-4) mg Force and (total mass) A(m+M) where m and M are defined in the manual and g is the acceleration due to gravity. Traditionally the form of a linear equation is given as (4.4a) Where m is not the same as the m in equation 4.4. If you truly understand the meaning ofequation 4.4a, this lab will be a piece of cake. We are going to test the following hypothesis: You do not understand equation 4.4a. You can blithely make many statements about the equation, but I posit you do not understand it. Let's test the hypothesis. 1. State the physical meaning of the Y in equation 4 4a. It is NOTE: There is more than one correct answer. I will accept any correct answer. 2. State the physical meaning of the m in equation 4.4a. It is the 3. State the physical meaning of the xin equation 4.4a. It is the NOTE: Again there is more than one correct answer. 4. What is the meaning of the b in equation 44a. It is NOTE: Again there is more than one correct answer. 5. In equation 4.4a, which term is always the same (constant) regardless of the coordinate system chosen? Le regardless of the choice of origin of coordinates 6. In equation 4.4a, which constant term changes when you change coordinate system e, change the origin of coordinates 7. In any equation of a straight line, which term is always constant regardless of the choice ofcoordinate system? 8. In any equation of a straight line, what value does the slope

Explanation / Answer

1-Y is the acceleration of the mass. It's plotted on the y axis of the graph.

Y= g * m/(m+M)

2- So the graph can be plotted between the acceleration on y axis and m/(m+M) on x axis

So the slope of the graph is the" m" and it's value will give us the value of g .

3- X is the values of m/(m+M)

Which is varied for different sets of the experiment

4- Typically the value of b should be zero.. But in this case the value of b is the intercept on the y axis. Which is the error in the experiment

* solving first four subparts only.
