<u>Answer;</u>
-Work
If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, <u>work </u> is being done.
<u>Explanation;</u>
- Work refers to the application of a given force over a distance. Thus, we can say work is the product of force and distance.
- Energy on the other hand is the ability of a body to change, its location, shape, or state of another body.
- According to the work-Energy principle, a change in the kinetic energy, which is the energy possessed by a body in motion, is equivalent to the net work done on the body.

Compound Element
Definition A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom.
Representation A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound. An element is represented using symbols.
Composition Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined. Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.
Examples Water (H2O), Sodium chloride (NaCl), Sodium bicarbonate (NaHCO3) etc. Hydrogen (H), Oxygen (O), Sodium (Na), Chlorine (Cl), Carbon (C), Iron (Fe), copper (Cu), silver (Ag), gold (Au) etc.
Ability to break down A compound can be separated into simpler substances by chemical methods/reactions. Elements cannot be broken down into simpler substances by chemical reactions.
Types A huge, virtually limitless, number of chemical compounds can be created. Compounds are classified into molecular compounds, ionic compounds, intermetallic compounds and complexes. There are about 117 elements that have been observed. Can be classified as metal, non-metal or metalloid.
The statement that the friend made is not true. most of the mass of the plant is from carbon. the carbon comes from carbon dioxide which is used during photosynthesis. the left over carbon from photosynthesis is used to to help the plant gain mass. there is a process for this which is called cellular respiration
You can think like this, Velocity is speed with a direction. When you say, the car was moving at the speed of 20 kilometers per hour, that's speed. But if you say, the car was moving at the speed of 20 kilometer per hour to the east. That's velocity, because you also stated the direction of the car.
