Newtons First Law
What is Newton's first name?
Isaac Newton
What are the equations for Newton's second law?
Fnet = MxA
A = Fnet/M
M= A/Fnet
Is there a Newton's Fourth Law?
No
Law of Inertia
Newton's First Law
If the net force of an object is ___, then that object will have zero acceleration.
If the net force on an object is zero, then that object will have zero acceleration.
Objects will _____ in the direction of the net force
Objects will accelerate in the direction of the net force.
For every action force, there is an ____ and ______ reaction force.
For every action force, there is an equal and opposite reaction force.
This law focuses on directly proportional and inversely proportional relations.
Newton's Second Law
What kind of forces cause an object to speed up, slow down, or change direction?
Unbalanced Forces
Larger _____ require greater ___ _____ to accelerate the same amount.
Larger masses require greater net force to accelerate the same amount.
If object A exerts a _____ on object B, object B also exerts an ____ and opposite ____ on object A
If object A exerts a force on object B, object B also exerts an equal and opposite force on object A
This law contains the equation a = Fnet/M
Newton's Second Law
An object at ___ will stay at ___, or in motion, remains in motion at a _____ constant velocity unless acted on by a net _____ force.
An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
What is Newton's Second Law?
Hint: Law of M_____
Law of Momentum
What is Newtons Third Law known as?
Hint: Law of A____ & R_____
Law of Action & Reaction
Which law focuses on force pairs?
Newton's Third Law
What is Newton's First Law?
Hint: Law of I-
The Law of Inertia
Acceleration of an object produced by a net force is directly related to _____.
Acceleration of an object produced by a net force is directly related to the magnitude of the force.
Which of these are an example of Newton's Third Law:
- Dust coming out of mat when beaten.
- Firing of a bullet
- A ball rolling down a hill
Firing of a bullet
When a bullet is shot from a gun, the gun puts a force on the bullet that propels it forward
This law was founded by Newton studying the results of Galileo Galilei.
