Proportional Reasoning in Physics Quiz

What is the primary purpose of using proportional reasoning in physics?

• To calculate exact values of variables

• To understand the relationship between variables

• To memorize equations

• To avoid using equations

In the context of centripetal force, if the velocity of an object is increased fivefold, how does the required force change?

• It decreases by a factor of 5

• It doubles

• It remains the same

• It increases by a factor of 25

When the distance between two masses is tripled and one mass is doubled, how does the gravitational force change if the second mass is adjusted to make the force four times stronger?

• The second mass must be 2 times larger

• The second mass must be 18 times larger

• The second mass must be 4 times larger

• The second mass must be 9 times larger
