Question

read the passage and use it to determine the meaning of the terms. not all answer choices will be used. the kinetic energy of an object is the energy that comes from motion. atoms and their components are constantly in motion, so all matter inherently possess kinetic energy. any object in motion also has kinetic energy. things with kinetic energy are capable of doing work. you can calculate the kinetic energy of a moving object based on its mass and velocity. objects with a greater mass and/or velocity will have more kinetic energy. use the following equation to calculate kinetic energy: kinetic energy (ke) = ½ mass x velocity² potential energy, on the other hand, is the energy held by an object due to its arrangement or position relative to other objects. this is stored energy that has the potential to do work. when a person or object is positioned above the earth’s surface with the potential to jump or fall, this is referred to as gravitational potential energy. examples of this are a diver standing on a diving board, a sled on the top of a hill of snow, and a gymnast on a high beam. potential energy due to an object’s shape is called elastic potential energy. this type of energy results from when an object is stretched or compressed. one example of this is when shooting an arrow from the bow and the bow is stretched back before the arrow is released. the formula for calculating the potential energy is the same as the formula to find work: w = fd where w is work, f is force, and d is distance. potential energy is converted to kinetic energy as soon as the object goes into motion. ---definitions--- 1) kinetic energy l) the action of an object changing its position. 2) motion r) a push or pull that influence motion of an object. 3) atoms c) a measure of the amount of matter in an object. 4) work g) energy that is stored in an object and can cause change when released. 5) mass n) an object’s change in velocity. 6) velocity h) the speed of something in a direction. 7) potential energy e) the energy an object possesses due to its motion. 8) gravitational potential energy b) the energy an object possesses because of its position in a gravitational field. 9) elastic potential energy w) a type of potential energy that is stored when materials stretch or compress. t) the tendency of an object to resist a change in motion. m) the basic unit of a chemical element. d) the energy transferred when an object is moved by a force over a distance. ---secret code--- cross out the letters of the matching definitions every time they appear in the secret code. rewrite the leftover letters in order to reveal a clue about the masked scientist. spaces between any words are not included. nmhotcanedwhlbarmgtbilgwestd

Explanation:

1. Kinetic Energy: The passage states "The kinetic energy of an object is the energy that comes from motion", so it matches E. The energy an object possesses due to its motion.
2. Motion: Motion is the action of an object changing its position, so it matches L.
3. Atoms: Atoms are the basic unit of a chemical element, so it matches M.
4. Work: Work is the energy transferred when an object is moved by a force over a distance, so it matches D.
5. Mass: Mass is a measure of the amount of matter in an object, so it matches C.
6. Velocity: Velocity is the speed of something in a direction, so it matches H.
7. Potential Energy: Potential energy is energy that is stored in an object and can cause change when released, so it matches G.
8. Gravitational Potential Energy: Gravitational potential energy is the energy an object possesses because of its position in a gravitational field, so it matches B.
9. Elastic Potential Energy: Elastic potential energy is a type of potential energy that is stored when materials stretch or compress, so it matches W.

After crossing - out the relevant letters in "NMHOTCANEDWHLBARMGTBILGWESTD", we need to perform the letter - crossing operation to get the clue.
