Question

Describe the relationship between speed and kinetic energy.

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

D) A positive but not linear relationship

Step-by-step explanation:

Speed is equal to distance divided by time. ... Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.

Answer 2

D) A positive but not linear relationship

Step-by-step explanation:

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.
