PHYS 200 Unit 10: Rotational Motion and Angular Momentum
Flashcards do conjunto (17)
- 1uniform circular motion-motion with constant angular velocity
-ω = Δθ / Δt - 2angular acceleration-rate of change of angular velocity with time
-α = Δω / Δt - 3linear/tangential acceleration-acceleration in direction tangent to circle at point of interest in circular motion
-a_t = Δv / Δt - 4linear and angular displacement-x = θr
-θ = x/r - 5linear and angular velocity-v = rω
-ω = v/r - 6tangential and angular acceleration-a_t = rα
-α = a_t/r - 7Rotational Kinematic Equations-θ = ωt
-ω = ω_0 + αt
-θ = ω_0t + 1/2 αt^2
-ω^2 = ω_0^2 + αθ - 8moment of inertia-mass times the square of perpendicular distance from the rotation axis
-I = mr^2 (particle) - 9moment armperpendicular distance to axis of rotation
- 10torque, angular acceleration, and moment of inertia- τ = (m^2 r)α
-net τ = Iα - 11force and angular acceleration-F = mrα
- 12rotational kinetic energy-KE_rot = 1/2 I ω^2
- 13mechanical energy with rotational motion1/2 m v_1^2 + 1/2 I ω^2 + mgh_1 = 1/2 m v_2^2 + 1/2 I ω_0^2 + mgh_2
- 14Work-Energy Theorem with Rotational Motionnet W = 1/2 I ω^2 - 1/2 I ω_0^2
- 15angular momentumL = I ω
- 16torque and angular momentumnet τ = ΔL / Δt
- 17law of conservation of angular momentum-L = constant
-L = L'
