Newton's First Law of Motion Flashcards
is the tendency of the object to resist
changes in its motion or the tendency to remain in its position or to keep on doing what it is doing.
Inertia
It varies with mass.
Inertia ( 2 )
The more mass an object has, the more
____ it possesses.
Inertia ( 3 )
is the amount of matter that an object possesses.
Mass
It is also used to describe how
much inertia an object has. Its unit of measurement is kilogram (kg).
Mass ( 2 )
The _____ of an
object remains constant and is not dependent on the force of gravity.
Mass ( 3 )
is the force exerted on an object due to the force of gravity.
Weight
It is also the product
of mass and acceleration due to gravity (g).
Weight ( 2 )
The _______ of an object may vary
depending on the force of gravity present in a specific location.
Weight ( 3 )
Its unit of measurement is kg*m/s2 or Newton (N).
Weight ( 4 )
what is the formula of weight?
W = mg ( Weight = mass of object x acceleration of gravity )
The ________________ (g) varies depending on the pull of gravity. On earth,
the ____________________ (g) is equal to 9.8 m/s 2 while the gravity on the moon is
1/6 of that on earth so the ___________________ (g) on the moon is equal to 1.63
m/s 2 .
Acceleration Due To Gravity
what is the acceleration due to gravity on earth?
9.8 m/s2 ( power of two )
what is the acceleration due to gravity on the moon?
1.63 m/s2 ( power of two )
what law is this?
“An object at rest stays at rest and an object in motion stays in
motion with the same speed and in the same direction unless acted
upon by an unbalanced force.”
Newton’s First Law Of Motion
( TRUE OR FALSE )
An object with more mass will have more weight.
True
( TRUE OR FALSE )
The mass of an object varies depending on it’s location
False
( TRUE OR FALSE )
Weight is the result of air pressure exerted upon an object.
False
( TRUE OR FALSE )
The more mass the object has, the more inertia it possesses.
True
( TRUE OR FALSE )
An object weighs less on the moon than it does on the Earth.
True
( TRUE OR FALSE )
Inertia is the tendency of an object to resist change in motion.
True
( TRUE OR FALSE )
The mass of an object on the moon is the same as its mass on the Earth.
True
( TRUE OR FALSE )
The weight of 1 kg on Earth is 9.8 kg.
False
A man weighs 882 N on earth. What is his mass in kg?
90 kg ( Formula : w/g )
from the last question, what will be the weight of the man in the moon?
146.7 N ( Formula W = mg ) = 90kg x 1.63
