Which is a good description of kinetic energy?
conserved energy
stored energy
energy from the sun
energy of motion
A person throws a ball up into the air. At which point in its path will the ball have the greatest potential energy?
when the ball reaches its highest point
when the ball leave the persons hand
when the ball is still rising
when the ball hits the ground
Two students drop an object into sand from a height of 1.5 meters. They record the depth of the hole made in the sand by each student’s object. What is the most likely explanation for the results?
Maddie's object had a faster drop speed.
Naveed's object had greater kinetic energy.
Maddie's object has a smaller width.
Naveed's object has less mass.
I WONT WRITE LETTERS BECAUSE IT VARYS FROM TEST TO TEST!!!
1. Energy of motion.
2.when the ball reaches its highest point
3. Naveed’s object had greater kinetic energy.
4. She should drop two balls with different masses from the same height.
5.10 grams of water, falling at 1 m/s
6. The kinetic energy of the man is greater because he has more mass than the woman.
7.The spot with the “maximum kinetic energy” should be on the lowest point of the roller coaster, at the far left side on the bottom.
8.None of the balls will have a velocity greater than 20 m/s.
9.rapids dam: fall height of 175 feet
10. to allow the kinetic energy of the water to increase greatly before reaching the turbines
11. (My answer) At max height of swing, potential energy is greatest, kinetic energy is least. At the bottom of the arc, potential energy is least, and kinetic energy is max
12. (My answer) The 16 pound shot will have more kinetic energy that the 12 pound shot. This is because the 16 pound shot is heavier than the 12 pound shot. Even though the 12 pound shot went farther, that doesn't mean it has more kinetic energy.
THESE ARE 100% CORRECT!! I HOPE I HELPED :)))
emma the answers to the test are
1. Energy of motion.
2.when the ball reaches its highest point
3. Naveed’s object had greater kinetic energy.
4. She should drop two balls with different masses from the same height.
5.10 grams of water, falling at 1 m/s
6.The spot with the “maximum kinetic energy” should be on the lowest point of the roller coaster, at the far left side on the bottom.
7.(my answer) At max height of swing, potential energy is greatest, kinetic energy is least. At the bottom of the arc, potential energy is least, and kinetic energy is max
hope this helped
all yall with 10 questions here you are remember connexus 6th
1. energy of motion
2. when the ball reaches its highest point
3. naveeds object has greater kinetic energy
4. She should drop two balls with different masses from the same height.
5. 10 grams of water falling at 1 m/s
6. The spot with the “maximum kinetic energy” should be on the lowest point of the roller coaster, at the far left side on the bottom.
7. dam A: fall height of 175 feet
8. to allow the kinetic energy of the water to increase greatly before reaching the turbines
9. (my answer use as you please) first when she gets pushed (if any) the person transfers potential energy into kinetic when they touch the child. then it goes into potential and back into kinetic when she's in motion. then at the highest point that's the spot with the most potential energy. then the spot with the best kinetic energy is right in the middle of the swing.
10. (the i d i o t s answer) The 16 pound shot will have more kinetic energy that the 12 pound shot. This is because the 16 pound shot is heavier than the 12 pound shot. Even though the 12 pound shot went farther, that doesn't mean it has more kinetic energy.
your welcome :)))) triple chins
9.Kinetic energy is at its max at the starting point from where they started and potential energy is at its max at the highest part when they swing.
10.The 16-pound shot weighs more and has more kinetic energy than the 12-pound shot. The 12-pound shot weighs less and has more potential energy that the 16-pound shot. Therefore the 12-pound shot will go farther.
This is what I got for the short answer questions.
(BTW put it in your own words if you use this its just for help)
I only have 10
I have ten questions
nvm it is i got a good grade! tysm!!!!!!👍👍👍👍👍👍👍👍
10/10 The kids above me are right as well, I just provided an updated version
1. energy of motion
2. when the ball reaches its highest point
3. Naveed's object had greater kinetic energy
4. she should drop two balls with different masses from the same height
5. 10 grams of water falling at 1 m/s
6. the spot with the "maximum kinetic energy" should be on the lowest point of the roller coaster, at the far left side on the bottom
7. dam A: fall height of 175 feet
8. to allow the kinetic energy of the water to increase greatly before reaching the turbines
9 AND 10 look above for explanations.
