Chapter 1
The units for length, mass, and time (as
well as a few others), are regarded as
base SI units.
Measurement
In this chapter we will explore the following concepts:
These units are used in com

Kinetic Energy and Work
Work: (symbol W)
If a force F is applied to an object of mass m it can accelerate it and increase
its speed v and kinetic energy K. Similarly F can decelerate m and d
