Forces
a body at rest tends to remain at rest
KE=1/2mv^2, why does this equation exist?
this equation exists to show the total work done to accelerate an object of mass from rest to a specific velocity
What is the momentum equation?
P=mv
What is the equation for light waves?
v = 𝛌f
Do resistors oppose flow?
Yes
F=mg, why does this equation exist?
This equation exists so we can measure the force of gravity acting on an object's mass, using weight
KE=kinetic energy
measured in Joules (J)
P=mv, why does this equation exist?
This connects how heavy an object is to how fast it is moving, allows for conservation of momentum
v = 𝛌f, why does this equation exist?
to explain the relationship between how fast a wave travels, how often it oscillates, and the length of one complete cycle
What type of pathway does a series circuit rely on?
Only one path for current to flow
what does the "F" stand for in the equation F=mg?
F= the force/weight
Measured in Newtons (N)
what does the "m" stand for in the equation KE=1/2mv^2?
m=mass of an object
measured in kilograms (kg)
what does the "P" stand for in the P=mv equation?
P=momentum
measured in kilogram meters per second (kgm/s)
what does the "v" stand for in the equation v = 𝛌f?
v= velocity
measured in meters per second (m/s)
Multiple paths for current, voltage stays the same across all branches is what kind of circuit?
Parallel circuit
what does the "m" stand for in the equation F=mg?
m=mass
measured in kilograms (kg)
what does the "v" stand for in the equation KE=1/2mv^2?

A short occurs
what does the "g" stand for in the equation F=mg?
g= gravity
earth's gravity = 9.81 m/s^2
A 10kg object is moving at 3m/s.
What is the kinetic energy?
KE= 45 J
v=velocity
