PLEASE CHECK MY ANSWERS———————————————– ————— — An object falls through the air, gaining speed as it falls. A student claims that it creates new energy and it breaks the law of conservation of energy. Which statement describes why the student is incorrect? (1 mark)
A. Energy can be created without breaking the law of conservation of energy.
B. Speed is in no way related to energy.
C. Energy is converted from other forms, not created.
D. Equal and opposite amounts of other energies are also created.
A person throws a ball in the air and the ball falls back to Earth. At what point would the kinetic energy be the lowest? (1 mark)
A . when the ball leaves the person’s hand
B. one point before the ball touches the ground
C. when the ball is at its highest point
D. at a time when the ball is still rising
A book lies on a flat table. The book is pushed, causing it to move and eventually come to rest again. How does the potential energy change during this process? (1 mark)
A. Potential energy first increases and then decreases to zero.
B. Potential energy initially decreases as kinetic energy increases.
C. The potential energy will remain the same as long as the book remains on the table.
D. The potential energy will remain the same unless the book speeds up or slows down.
What is a good description of potential energy? (1 mark)
A. stored energy
B. reaction energy
C. conserved energy
D. motion energy

4. A The answers are
1. Energy is converted from other forms, not created.
2. when the ball is at its highest point
3. The potential energy will remain the same as long as the book remains on the table.
4. Stored energy
It was nothing! ^that’s actually true 100 hhhhhhhhhhhhhhhhhhhh Thanks Micholow Micholow is right. Thanks! Micholow is 100% correct. Ty Micholow! Micholow is right 4/4 100% (: “_” @Micholow, thank you very much! You are 100% right! Micholow is right!!!!!!!!!! micholow is right thank you micholow is right 🙂 Thank you my mighty young, may the galaxy be on your side, and may the force be with you all. 1. Energy is converted from other forms, not created.
2. when the ball is at its highest point
3. The potential energy will remain the same as long as the book remains on the table. The kinetic energy increases as the book is pushed across the table.
4. inertia
5. A body in motion will remain in perpetual motion until it is subjected to a force. / A force is needed to change the direction of motion of an object.
Hope this helps 😀
ps i never say the wrong answers so pay attention to my user
~ The Nerd is called hypocrisy Micholow is right Micholow 💯 %RIGHT thanks man what’s the answer Stop cheating why are you on this then? How did you come to this site? THANK YOU SO MUCH I NEED ALL THE HELP I CAN GET FROM YOU AND MY TEACHERS ARE THEY NEVER WANT TO HELP ME SO THAT’S WHY I AM ON THIS WEBSITE. THANKS A LOT 😭! I thought I had to look everywhere but no. I trust him 100%👍🏼😌😁 Thanks nerd! 😀✨🤍 Micholow isn’t really wrong, the answers probably weren’t for the connexus, that’s why you still have to scroll through the answers even if you’re scrolling through them, those are the correct ones Thanks *ribbit* the connection is correct thank you very much. “Micholow” is 100% correct. thanks Micholow Noise SUSSSSSSSS Thanks @Micholow! i have five questins i have 5 questions- np @Ur mom if you need help with the lessons just tag me and lesson names i will say ok @Nerd is ok except for me the last was a different question. thanks anyway. Np @Charlie Emily 😉 1.D

4.B Q1: An object falls through the air, gaining speed as it falls. A student claims that it creates new energy and it breaks the law of conservation of energy. Which statement describes why the student is wrong?
– Energy is converted from other forms, not created.
Q2: A person throws a ball in the air, and the ball falls back to Earth. At what point would the kinetic energy be the lowest?
– when the ball is at its highest point
Q3: A book is placed on a flat table. The book is pushed across the table, causing it to move and eventually come to rest again. How do potential and kinetic energy change during this process?
– The potential energy will remain the same as long as the book remains on the table. The kinetic energy increases as the book is pushed across the table.
Q4: What is a good description of potential energy?
– stored energy
as of 9/29/22, these are the correct answers. Micholow is wrong, I got 3/5! If you didn’t know the answers without cheating something tells me you really need to study I just used it to check my answers if you want help or something ask your teacher(s) !
