Answer:
Describe the scientific method/process and list its steps:
The scientific method consists of six steps:
1. Define purpose
2. Construct hypothesis
3. Test the hypothesis and collect data
4. Analyze data
5. Draw conclusion
6. Communicate results
But what is it?
The scientific method is a process with the help of which scientists try to investigate, verify, or construct an accurate and reliable version of any natural phenomena.

Define speed and velocity:
Speed is the quantitative measure of how quickly something is moving. Velocity defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance.
List the three Laws of Isaac Newton and provide an example for each law.
1 - An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
(example: A coin put on top of a paper on the table will stay in place when the paper is pulled.)
2 - That force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration, i.e. F = m*a.
(example: A truck which carries less mass will have a bigger acceleration that a truck which carries more mass)
3 - States that for every action there is an equal and opposite reaction.
(example: Our hand feels pain when we hit the table because the table gives force as a reaction to our hand)
List the two types of waves.
1. Mechanical Wave --> A mechanical wave is a wave that is an oscillation of matter and is responsible for the transfer of energy through a medium.
2. Electromagnetic Wave --> Electromagnetic waves are created by a fusion of electric and magnetic fields. The light you see, the colours around you are visible because of electromagnetic waves.

Discuss what is electromagnetism.
Electromagnetism is a branch of physics that is about the electromagnetic force that is between electrically charged particles. Electromagnetism is the basic reason why the electrons are bound to the nucleus and responsible for the complete structure of the nucleus!
