Here's my answers to Unit 4, Lesson 8
Energy of Motion Apply practice
1)Kinetic energy
2)Potential energy will decrease in an amount equal to the increase in kinetic energy.
3)Small rock
4)Decrease its speed
5)The object with the greater mass.
6)All have the same potential energy, because they are all travelling an equal distance of one step at a time.
7)She has high potential energy and low kinetic energy
8)It is lost by the bowling ball, which would have a smaller decrease in velocity.
9)The child will move up at a faster speed because the child has less mass.
10)Energy changes from potential to kinetic to electric.
11)A place where the wind has more kinetic energy to covert into electric energy.
Error is right!
yall its a practice
Error is 100%
Review the definition of "kinetic" and you may want to revise your first answer.

Your second answer is also wrong, because "positional energy" is not an accepted term. The correct answer looks a little bit the same.

If you're in connexus, and it's a practice. There's no point of cheating, it doesn't affect your grade, and it has a check answer thing.
To determine the correct answers to these questions, we need to understand what each energy form represents.
For the first question:
a. Potential energy is the energy stored in an object due to its position or configuration.
b. Elastic potential energy is the energy stored in a stretched or compressed elastic object, such as a spring.
c. Nonmechanical energy refers to forms of energy that are not associated with the motion or position of an object, such as thermal or chemical energy.
d. Kinetic energy is the energy of an object in motion.
Based on these definitions, the correct answer for the first question is indeed d. Kinetic energy. This is because kinetic energy is directly associated with the motion of an object.
For the second question:
a. Potential energy, as mentioned earlier, is the energy stored in an object due to its position or configuration.
b. There is no specific energy form called "positional energy." So, this option is incorrect.
c. Total energy refers to the sum of all forms of energy present in a system. While positional energy contributes to total energy, it is not a specific energy form.
d. Kinetic energy is the energy of an object in motion.
Therefore, the correct answer for the second question is a. Potential energy. This is because potential energy is associated with an object due to its position, which aligns with the given description.
I hope this helps clarify the correct answers for you!
