Question

acceleration vs. mass graph

- graph: parabola

- inversely proprtional

- negative correlation

- one increases, the other decreases

- change by the same factor

acceleration vs. 1/mass graph

- graph: straight line

- DIRECTLY proportional

- positive correlation

- decrease together, increase together

- change by the same factor

is whats written correct?

(force is constant)

Answer #1

The expression of force f = m*a :f=force m = mass a =acceleration

In the acceleration v/s mass graph for a constant force when the mass increses then the acceleration decreases. They are said to be inversely proportional. So the graph look like a hyperbola. They follow a negative correlation and change by the same factor.

The acceleration v/s 1/mass graph when the mass increases the acceleration also increases..they are said to be directly proportional. They follow a positive correlation and change by the aame factor. Since they are directly proportional, the graph will be a straight line

correlation measures the degree to which two variables are
related to one another.
Here are the definitions of the three possibilities:
Positive correlations: In this type of
correlation, both variables increase or decrease at the same time.
A correlation coefficient close to +1.00 indicates a strong
positive correlation.
Negative correlations: This type of
correlation indicates that as the amount of one variable increases,
the other decreases (and vice versa). A correlation coefficient
close to -1.00 indicates a strong negative correlation....
