Graphs
Velocity vs Time graph with constant velocity
Straight Line
Distance
Total path length of an object (meters)
What is momentum?
P=mv or a vector
For the equation of Fg, what happens when you double one mass and halve the other
Stays the same
What is Newton's first law?
An object in motion stays in motion until an unbalanced force acts on it.
Free fall distance over time graph
positive exponential
Scalar
Measurement with just magnitude
ex) time, energy
What is Initial momentum equal to?
Final momentum
For the equation of Fg, what happens when you double the radius of the object?
It is 1/4th as much
AKA
Every action has an equal and opposite reaction.
Net force vs acceleration, what does the slope represent?
Mass
Displacement
Vector that goes directly from beginning to end (meters)
What is impulse?
You must apply a net force for an mount of time to change an object's momentum
also a vector
For the equation of Fg, what happens when you triple the radius?
1/9th as much
What is Newton's second law?
F(net)=ma
Decreasing exponential
Vector
Measures both magnitude and direction
ex) velocity, momentum
What is the equation for impulse/change in momentum?
J=FnetT=Delta P
For the equation of Fg, what happens when you triple both the masses?
Nine times as much
Hooke's Law
Fs=kx
force of a spring=(spring constant)(elongation of the spring)
Distance
Instantaneous velocity
The velocity at a precise time in the object's journey
What is one law of the conservation of momentum?
1. All matter in the universe has momentum
or
2. All momentum in the universe never changes, it's conserved
For the equation of Fg, triple both masses and halve the radius
36 times as much
What is one rule of Friction
1. Surface Area is irrelevant no matter the size
2. If you increase Fn, Ff goes up
3. Static friction is always greater than kinetic friction
4. Mu is the slope of Ff vs Fn
