(PE= m x g (9.8) x h)
Question 6
6.
How would the PE of the DVD case on the desk change if it were now on the moon (g=1.6 N/kg)? Support your claim with evidence (show the math and the PE of each location).
Use the Kinetic Energy: Changing Mass chart below to answer questions 7-11. Round all number to the nearest ten thousanths place (four after the decimal).
Question 7
7.
Using the Kinetic Energy: Changing Mass chart above, calculate the KE of the car when it has no marbles.
KE = (1/2 mass) x (velocity2)
Question 8
8.
Using the Kinetic Energy: Changing Mass chart above, calculate the KE of the car when it has one marble.
KE = (1/2 mass) x (velocity2)
Question 9
9.
Using the Kinetic Energy: Changing Mass chart above, calculate the velocity of the car when it has two marbles.
(v=d/t)
Question 10
10.
Using the Kinetic Energy: Changing Mass chart above, calculate the velocity of the car when it has three marbles. (v=d/t)
Question 11
11.
What evidence do you see in the data above that supports the claim "when mass doubles, the KE doubles and when velocity doubles, KE increases by a factor of four?" Explain your reasoning with evidence directly from the data chart.
Use the Kinetic Energy: Changing Velocity chart below to answer questions 12-16. Round all number to the nearest ten thousanths place (four after the decimal).
Question 12
12.
Using the Kinetic Energy: Changing Velocity chart above, calculate the velocity of the car when it has a height of 4. (v=d/t)
Question 13
13.
Using the Kinetic Energy: Changing Velocity chart above, calculate the velocity of the car when it has a height of 8. (v=d/t)
