Free Fall
|
The motions of an object when it is falling solely under the infulence of gravity
|
|
|
Terminal Velocity
|
The velocity a falling object has when, due to air resistance, its accerleration is reduced to zero. This is the mazimum velocity a falling object subject to air resistance can achieve.
|
|
|
Fact 1:
|
Equations (2.6), (2.15), and (2.19) are valid only when the accerleration is constant.
|
|
|
Fact 2:
|
Objects falling near the surface of the earth experience a constant acceleration of 9.8 m/sec2 (32 feet/sec2) straight down.
|
|
|
Fact 3:
|
The acceleration due to gravity is independent of the nature of the object experiencing free fall, as long as the object has mass.
|
|
|
Fact 4:
|
When an object is thrown upward in the presence of gravity, the object will reach its maximum height when the object's velocity equals zero. In addition, when it returns to the height from which it was thrown, its velocity will be equal to and opposite of its initial velocity.
