1.Which is a good description of kinetic energy?
energy of motion
2.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
3.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?
Naveed's object had greater kinetic energy
4.A student wants to determine the effect of mass on kinetic energy. She will drop two balls of the same size into a pool of water. Which investigation method should the student use?
She should drop two balls with different masses from the same height
5.Which falling object will result in the least kinetic energy when it collides with the ground?
10 grams of water falling at 1m/s
6.This image of a roller coaster is designed to show important information about potential and kinetic energy. One of these labeled pieces of information is incorrect. Which information is wrong, and why?
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.A child is swinging back and forth on a swing. Changes in her kinetic and potential energy are happening each moment. At which point, or multiple points, in her swinging would each of these two types of energy be at a maximum? In one to two sentences, describe these points and which type of energy is at a maximum at each point.
for this one i cant give a straightforward answer because you will get in trouble for plagiarism but remember this, potential energy is greatest when an object is at its highest point, and kinetic energy is greatest when an object is at its lowest point. when potential energy is at its greatest point, kinetic energy is at its lowest point, vice versa.
GOODLUCK!

Correct Answer: Energy of motion
You are all welcome
The correct answer is "energy of motion." To determine this, we can look at the options provided and evaluate their accuracy.
1. Stored energy: This refers to potential energy, which is the energy that an object possesses due to its position or state. It is not the same as kinetic energy, which is associated with the motion of an object.
2. Conserved energy: Conservation of energy refers to the principle that energy cannot be created or destroyed, but it can be converted from one form to another. It does not directly describe the nature of kinetic energy.
3. Energy of motion: This is the most accurate description of kinetic energy. Kinetic energy is the energy an object possesses due to its motion. The faster an object moves or the greater its mass, the higher its kinetic energy.
Therefore, the best description of kinetic energy among the given options is "energy of motion."
