Chapter 1: Kinematics and Dynamics Flashcards
What are the equations to find the x- and y- component vectors?
X = Vcosθ
Y = Vsinθ
Dot product
Cross product
(average) velocity
4 kinematic equations (linear motion w/ constant acceleration)
Force of gravity (on earth)
9.8 m/s^2
Acceleration equation
a = delta V / delta T
Gravitational force equation
Define friction
the force that opposes the movement of objects
What are the 2 types of friction?
static and kinetic
Static friction (definition + equation)
the force between a stationary object and the surface it sits on
Kinetic friction (definition and equation)
the force between a moving/sliding object and the surface it slides on
Newtons first law
F = ma = 0
Law of Inertia
an object at rest or in motion will stay that way unless it is acted on by a net force
Newtons second law
F = ma
an object of mass will accelerate when the vector sum of the forces results in a nonzero resultant force vector
Newton third law
Fab = -Fba
to every action there is an equal and opposite reaction
for every force exerted by A on B, B exerts the same force back on A
Centripetal force equation
Joule units
“Newton meters”
(hint: work = force x displacement → joules = newton x meter)
Newton units
