How would you describe the relationship between the mass of a car and its kinetic energy?

a) as the mass of a car increases, its kinetic energy increases.
b) as the mass of a car increases, its kinetic energy decreases.
c) as the mass of a car decreases, its kinetic energy increases.
d) there is no clear relationship between mass and kinetic energy.

A)As the mass of a car increases, its kinetic energy increases.

Explanation:

In the graph, the mass of the car is represented on the x-axis, while the kinetic energy is represented on the y-axis. We see that as the value on the x-axis increases, the value on the y-axis increases as well: so, the kinetic energy increases as the mass increases.

More specifically, there is a direct proportionality between the two variables. In fact, the equation that relates kinetic energy and mass is:

where

m is the mass

v is the speed

K is the kinetic energy
