Fields Flashcards
Altitude is ______ proportional to the gravitational field intensity.
Inversely.
As _______ increases the gravitational field intensity increases.
Latitude
True weightlessness can only happen if which two things occur?
The mass is zero or the gravitational field intensity is zero.
Apparent weight is referred to as
A) Fk
B) FN
C) Fg
B) FN
When does the apparent weight equal the true weight?
When Fnet is balanced, there is no vertical movement, and it has a constant velocity.
When acceleration is downward apparent weight will be less than or greater than the true weight?
It will be less than.
When apparent weight is greater than the true weight which direction will acceleration be in?
Acceleration will be upwards.
What force acts during free fall?
Only weight, Fd can be neglected.
Is there acceleration at terminal velocity.
No, acceleration would be zero.
What is an electric field?
It is a region in space around a charge where an electric charge experiences a force caused by the field.
Like poles ________, unlike poles ________.
Repel, attract.
What is a region in which a magnetic pole experiences a magnetic force?
A magnetic field.
What is a gravitational field?
It is a region in space in which mass experiences a force of gravity.
