1) A heavy object and a light object are in free fall, having
been dropped from equal heights. Which object strikes the
ground first? Explain your answer.
Two objects will be strike to the ground at the same time. Since
it have same initial velocity and s
1) What is the difference between base and derived units?
Base Units are like meter, kilogram and second that are
defined by standards.
Derived units are expressed by the combinations of base
2) How is unit analysis useful?
Unit analysis tell the c
1) Before you read this section, how did you define power?
Power is the necessary thing in order to working.
2) How will we define power in Physics?
The time rate of doing work.
3) Go out on the web and find an example of something that generates
1) What did you know about force before you read this
Force will change object velocity or acceleration.
2) What is the difference between force and net force?
Since force can produce acceleration, it has both magnitude
and direction. When severa

1) Before you read this section, what did you think
of when you heard the phrase circular motion?
The object that has motion with the circular path.
2) Define arc length. What two values must you
know to calculate the arc length?
In a circle, the length o
1) Discuss the similarity and difference between spring potential
energy and gravitational energy. Use between two and four
Gravitational energy is basically about high of object and it related
to mass and gravity.
According to the equ

In free body diagrams, we can represent force into x-y coordinate.
Since we need to be consider the direction and sometime we
need to brake force to two direction components. After draw free
