Question 11

Three best friends each play different sports and were curious about the relationship of mass to the kinetic energy of each of the balls they use to play. They calculated the kinetic energy of each ball using the approximate mass and a common velocity of 10m/s to compare them. The table below contains their data. Ball Type: Tennis Ball (60g, 3J), Baseball (150g, 7.5J), Soccer Ball (400g, 20J) Based on the data in the table, what can be concluded about the relationship between mass and kinetic energy?

Accepted Answer

The relationship between mass and kinetic energy is positive and proportional since the mass is 20 times the kinetic energy for each object.

Answer

The relationship between mass and kinetic energy is not proportional since the mass increases by different amounts for each object.

Answer

The relationship between mass and kinetic is negative and proportional since the kinetic energy is 1/20 of the mass for each object.

Answer

There is no relationship between mass and kinetic energy because the mass and kinetic energy change by different amounts for each object.
