Newton's Laws
p = m(v)
(p)Momentum = (m)Mass x (v)Velocity
Mass
A measure of Inertia
action-reaction force pairs
All forces act in pairs.
Law of Inertia (definition)
An object in motion will remain in motion at a constant speed and in the same direction unless acted on by an unbalanced force. An object at rest will remain at rest unless acted upon by an unbalanced force.
The Law of Inertia states -
An object in motion will stay in motion at a constant speed and in the same direction unless acted on by an unbalanced force
Acceleration
Depends on force and mass. Acceleration and force are directly proportional, this means as force increases, acceleration also increases.
What does F=m x a stand for?
Force = mass times acceleration
Acceleration and mass are BLANK?
Inversely proportional
Newtons First Law of Motion
Law of Inertia (answer)
Force
Mass (x) Acceleration
Cars automatic brake systems are an example of which of newton's laws?
Newton's First Law of Motion
Which of newton's laws can be explained by saying that a tractor trailer has more mass than a motorcylce?
Newton's first law of motion
which of Newton's laws states that an object with a small mass has less inertia than an object with a large mass
Newton's first law of motion
which of newton's laws says an object at rest will remain at rest unless acted upon by an unbalanced force
Newton's first law of motion
F=m.a is part of which of newton's laws?
Newton's second law of motion
which of newton's laws states that whenever one object exerts a force on a second object, the second object exerts a force that is equal in size and opposite in direction on the first
Newton's third law of motion
Did Newton discover all 3 laws of motion?
No. He explained them in a way that many people could understand
this statement is part of which of newton's law of motion....force causes an object to accelerate while the object's mass resists the accelerateion
Second Law of Motion
Newton's Second Law of Motion
The acceleration of an object depends on the mass of the object and the amount of force applied to it. F=m x a.
Newton's Third Law of Motion
When one object exerts a force on a second object, the second object exerts a force that is equal in size and opposite in direction on the first.
Momentum
a property of a moving object that depends on the objects mass and velocity
The larger the object, the more mass it has the harder it is to BLANK
accelerate
As mass increases, what happens to accelerations?
acceleration decreases as mass increases because they are inversely proportional.
As force increases what happens to acceleration?
acceleration increases also because they are directly proportional
Acceleration and force are BLANK?
directly proportional
third law of motion
for every action there is an equal and opposite reaction
action reaction forces
if a force is exerted, another force occurs that is equal in size and opposite in direction to the first
what does mass measure?
it measures an object's inertia
momentum depends on what two things?
mass and velocity
the more BLANK an object has, the harder it is to stop the object or change its direction
momentum
the more momentum an object has, the harder it is to ....
stop the object or change its direction
Inertia
the tendency of all objects to resist any change in motion
an object moving at a certain velocity will continue to move forever at that same speed and in the same direction unless an unbalanced force acts on it
unbalanced force
