Design Process Define the Problem Generate Concepts Develop a Solution Construct and Test a Prototype Evaluate the Solution Present the Solution This design process was developed based on the University of Maryland - College Park - IRB Research Project
First Law Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force. Rest and motion can be thought of as being opposite to each other. Rest is the state of an object when it is not changing position in relation to its surroundings. If you are sitting still in a chair, you can be said to be at rest.
Newton Second Law Force is equal to mass times acceleration. This law of motion is essentially a statement of a mathematical equation. The three parts of the equation are mass (m), acceleration (a), and force (f). Using letters to symbolize each part, the equation can be written as follows: f = ma By using simple algebra, we can also write the equation two other ways: a = f/m m = f/a
Newton’s Third Law For every action there is always an opposite and equal reaction. This law states that every action has an equal and opposite reaction. If you have ever stepped off a small boat that has not been properly tied to a pier, you will know exactly what this law means.
