Term
What are two characteristics of friction?
Definition

 

  1. Parallel to the contact surface
  2. Opposite to relative motion - direction that prevents surfaces from sliding past each other

 

Term
What is the difference between static and dynamic equilibrium?
Definition

  • Static equilibrium-velocities constant and equal to zero
  • Dynamic equilibrium-velocities constant and not equal to zero

Term
Power (instantaneous)
Definition
P = F(v*cosΘ)
Term
Kinematics
Definition

 

  1. vf=vo + at
  2. vf=xo + vot + .5(at2)
  3. vf2=vo2 + 2aΔx
Term
Circular motion
Definition

  1. a=v2/r
  2. F=mv2/r

Term
Friction
Definition

 

  1. fs≤μsFn
  2. fk=μkFn

 

Term
Hooke's Law
Definition
F=-kΔx
Term
Total energy transfer due to forces excluding heat
Definition
W=ΔK+ΔU+ΔE
Term
Impulse
Definition
J=Δp=FΔt
Term
How do ideal machines alter force and work?
Definition
Reduce force but don't change work
Term
How do ramps manipulate force and work?
Definition
Constant work: +d (ramp length) so -F
Term

How do levers manipulate force and work?

Definition
Constant torque: +l (lever arm) so -F
Term
How do pulleys manipulate force and work?
Definition
Constant work: +d (rope) so -F
Term
What is mass defect?
Definition
Difference between nuclear mass and summed mass of individual particles (binding energy)
Term
What is the difference between elastic and inelastic collisions?
Definition
Kinetic energy is conserved in elastic collisions but not inelastic ones.
