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
