Expert Solution
Step 1 Introduction
Note: As per Bartleby guideline only solution problem (1) has been done
Force:
A force is an impact that can cause an object's motion to change. A force can cause a mass entity to modify its velocity, i.e., to expedite. Subjectively, the force can be described as a thrust or a lift. A force is a vector quantity because it has both magnitude and direction. It is measured in newtons, the SI unit of mass (N).
