Basics of Graphing and Inertia | Linear Motion | Newtons 2nd Law | Newtons 3rd Law and Vectors | Momentum |
---|---|---|---|---|
What is the kilogram?
base unit for mass
|
What is Newton’s first law?
An object in motion stays in motion; an objects at rest stays at rest, until acted on by another force.
|
What is Newton's second law?
F=ma
|
What are three Vector quamtities?
Velocity, Displacement, Acceleration
|
What is Momentum?
symbolized by p
|
What is y=mx+b?
The simple equation for a straight line
|
what is inertia?
The force that resists the change of motion.
|
What is Velocity?
Speed in a direction vector
|
What is Newton’s 3rd Law?
For every action there is an equal and opposite reaction
|
What is Newton’s second law?
From which of Newton’s laws does F(delta t)=M(delta v) come from
|
What is Inertia?
An object at rest stays at rest; and object in motion stays in motion unless acted upon by an outside force
|
What is average speed?
Total distance/total time
|
What is a Scalar?
Quantities where direction in not counted
|
What are the steps for a graphical vector addition diagram?
Point of Origin
Get a scale Draw first point according to scale and connecting the rest head to tail Draw resultant from origin to head of last point |
What is an impulse?
Something that changes the momentum of an object
|
What is force normal?
The force that acts against force weight?
|
What is Net force?
The sum of all the forces acting on an object.
|
What are the 3 types of motion graphs?
Position-Time, Velocity-Time, Acceleration-Time
|
What is the resultant?
The sum of all the vectors
|
What is Newtons x Seconds?
measurement of an impulse
|
What is the 7 base units?
Meter, Kilogram, Kelvin, Second, Mol, Ampere, Candella
|
What is force normal?
The force that acts against force weight.
|
What is gravity?
-9.8 m/s^2
|
What is the mass of the object you hit?
The reason your toe hurts when you stub it
|
What is the Law of Conservation of Momentum?
All momentum in a collision is not lost, but transferred between the two objects
