Vectors Flashcards
What is the resultant?
The sum of multiple vectors
What is the equation used if the angle is between V and X-direction?
Vx = Vcos0
What is the equation used if the angle is between V and Y-direction?
Vy = Vsin0
For linear motion, v =
vo + at
For linear motion, x - xo =
vot + (at^2)/2
For linear motion, v2 =
vi^2 + 2a∆x
For linear motion, v =
(v0 + v) / 2
For linear motion, x - xo =
(v0 + v) / 2 * t
Force can be expressed in units of
N
What is the equation of Force?
F = ma
What is the equation of Weight?
W = mg
Force can be used interchangeably with
Weight
What is Newton’s first law?
Body at rest or in motion will remain so unless net force acts upon it
What is Newton’s second law?
F = m*a
What is Newton’s third law?
Everything has an equal but an opposite reaction
Tension is interchangeable with
Normal Force
What is the Gravitational F?
F = Gmm/r^2
Rotational equilibrium depends on:
- Magnitude of Force
- Direction of Force
- Distance from Force to Axis of Rotation
The more distance there is in torque the
Greater the force there is
Friction can be found between
Two objects
What needs to be overcome for movement?
Static friction
What is the equation for Kinetic Friction?
fK = µK•N
How is velocity in circular motion?
Tangent
