PHYS 200 Unit 6: Uniform Circular Motion and Gravitation
Flashcards do conjunto (21)
- 1uniform circular motionmotion of object in circular path at constant speed
- 2rotational angle-ratio of arc length to radius curvature on circular path
-Δθ = Δs/r - 3arc length-distance traveled by object along circular path
-Δs - 4radius of curvature-radius of circular path
-r - 5revolution-2π radians
- 6angular velocity-rate of change of angle with which object moves on a circular path
-ω = Δθ/Δt
-ω = v/r - 7linear velocity-v = rω
- 8centripetal acceleration-acceleration of object moving in circle directed toward center
-a_c = v^2/r
-a_c = rω^2 - 9centripetal force-any net force causing uniform circular motion
-perpendicular to path and pointing to center - 10centripetal force formulas-F_c = ma_c
-F_c = m (v^2/r)
-F_c = mrω^2 - 11centrifugal force-fictitious force that tends to throw an object off when the object is rotating in a non-inertial frame of reference
- 12banked curve-curve in road that is sloping in a manner that helps a vehicle negotiate the curve
- 13static coefficient of friction for banked curve-μ_s = v^2/rg
- 14angle of ideally banked curve-θ = tan^-1 (v^2/rg)
- 15Newton's Universal Law of Gravitation-every particle in universe attracts every other particle with force along line joining them
-force is directly proportional to product of masses and inversely proportional to square of distance between them - 16Newton's Universal Law of Gravitation formulas-F = G mM/r^2
-G = 6.674 x 10^-11 N x m^2/kg^2
-m and M: masses of two bodies
-r: distance between centers of mass
-F: magnitude of gravitational force
-mg = G mM/r^2
-g = GM/r^2 - 17Kepler's First Laworbit of each planet about Sun is ellipse with Sun at one focus
- 18Kepler's Second Laweach planet moves so that imaginary line drawn from Sun to planet sweeps out equal areas in equal times
- 19Kepler's Third Law-ratio of squares of period of any two planets about Sun is equal to ratio of cubes of their average distances from Sun
-(T_1)^2/ (T_2 )^2 = (r_1)^3/(r_2)^3 - 20Period and radius of a satellite’s orbit about a larger body M-T^2 = 4π^2/GM x r^3
-r^3 / T^2 = GM/4π^2 - 21altitude of satellite above Earthh = r - R_E
-r: distance between satellite and Earth
-R_E: radius of Earth
