Question

Describe the relationship between kinetic energy and speed. A) A positive linear relationship. B) A negative linear relationship. C) A negative, but not linear relationship. D) A positive, but not linear relationship.

Answer 1

The correct answer is D) A positive, but not linear relationship.

This comes from the equation Ek=1/2mv^2

Where Ek is Kinetic Energy, m is mass, and v is the speed (or velocity).

As we can see in the equation, the relation is not linear but quadratic and it is positive.

Answer 2

The graph slopes up, but the points do not make a single straight line. This indicates a positive, but not linear relationship.
