Question

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.
(chart: kinetic vs mass with x - axis labeled mass (range 0 to 6) and y - axis labeled kinetic energy, showing data points with an upward trend)

Explanation:

The scatter plot titled "Kinetic vs mass" shows that as the mass (x - axis) of the car increases, the kinetic energy (y - axis) also increases. By analyzing the trend of the data points (they go up from left to right), we can see that there is a positive relationship between mass and kinetic energy. Option A states this relationship correctly. Option B is incorrect as the trend is increasing, not decreasing. Option C is incorrect because a decrease in mass would correspond to a decrease in kinetic energy based on the trend. Option D is incorrect as there is a clear positive relationship.

Answer:

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