 Newtons 3 laws of motion 1.a body at rest stays at rest, a body in motion stay in motion (straight line) unless outside force acts upon it.2.F=ma3.for every force there is an equal and opposite force. (t/f) a body in translational equilibrium has a net force moving it at a constant velocity false, a body at translational equilibrium has zero net force formula for torque torque=rFsin() when calculating torque, what direction is positive, what is negative counterclockwise is positive, clockwise is negative formula for centripetal acceleration a=v2/r formula for centripetal force F=ma or F=mv2/r formula for work W=Fdcos()from pressure (isobaric process):W=P(Vf-Vi) units for work and energy? joule (kg-m2/s2) formula for mechanical kinetic energy? gravitational potential energy? KE=mv2/2 U=mgh formula for momentum p=mv formula for impulse? delta p or j=Ft=mv-mv0 formula for center of mass for m1 and m2 at x1 and x2 X=(m1x1+m2x2)/(m1+m2) (t/f) kinetic energy is conserved in a completely elastic collision true (t/f) momentum is not conserved in a inelastic collision false, momentum is conserved in both elastic and inelastic collisions formula for heat gained and temperature change Q=mc(Tf-Ti)c-specific heat what is heat of fusion energy required for phase change from solid to liquid formula for heat gained or lost during phase change Q=mLL-heat of transformation formula for first law of thermodynamic delta U=heat energy gained-work done by the system 2nd law of thermodynamic entropy of a closed system will either increase or remain unchanged density of water 1000 kg/m3 or 1g/cm3 formula for pressure P=F/A formula for absolute pressure P=surface pressure+density*gravity*depth what is gauge pressure pressure in excess to atmospheric pressure formula for buoyant force Fb=density*g*V a pipe of varying cross sections, how do fluid velocity and cross section area related? A1V1=A2V2 formula for Young's modulus Y=stress/strain stress (F/A)strain (delta L/L) Coulomb's law F=kq1q2/r2 formula for electric field (E) at a distance (r) from a charge (q) E=kq/r2 formula for force that a charge (q) experience in a electric field (E) F=qE since E=F/q unit for electric field Newton/Coulomb or Volt/meter AuthorAnonymous ID59679 Card SetMCAT PHYSICS 1 Descriptionstudying to be a docnform Updated2011-01-14T01:28:39Z Show Answers
