Measurement
1.2 Measuring things
We measure each quantity by its own unit or
by comparison with a standard.
A unit is a measure of a quantity that scientists
around the world can refer to.
This has to be both accessible and invariable.
For examp

2.2 Motion
We find moving objects all around us.
The study of motion is called kinematics.

Vectors
In Physics we have parameters that can be completely described by a
number and are known as scalars .Temperature, and mass are such
parameters
Other physical parameters require additional information about direction and
are known as vect
Chapter 7
Kinetic Energy and Work
In this chapter we will introduce the following concepts:
Kinetic energy of a moving object
Work done by a force
Power
In addition we will develop the work-kinetic energy theorem and
apply it to solve a variety of problem
8. component F.,. of a force that can act on a particle. If the particle begins at rest at x = 0,
what is its coordinate when it has (a) its greatest kinetic en ergy, (b) its greatest speed, and
(c) zero speed? (d) What is the particle direction of travel

Why is a door knob located as far as possible from the door hinge? When you want to
push open a door, you apply a force. Where you apply the force and in what direction you
push are also important. If you apply the same force at two points, one twi
