WebFind the moment of inertia of the rod and solid sphere combination about the two axes as shown below. The rod has length 0.5 m and mass 2.0 kg. The radius of the sphere is 20.0 cm and has mass 1.0 kg. Strategy Since we have a compound object in both cases, we can use the parallel-axis theorem to find the moment of inertia about each axis. WebMomentum is a Vector. Momentum is a vector: it has size AND direction. Sometimes we don't mention the direction, but other times it is important! One Dimension. A question …

WebSep 12, 2024 · Given the uncertainty in speed Δ u = 1.0 × 10 − 3 m / s, we have to first determine the uncertainty in momentum Δ p = m Δ u and then invert Equation 7.3.1 to find the uncertainty in position Δ x = ℏ 2 Δ p. Solution For the electron: Δ p = m Δ u = ( 9.1 × 10 − 31 k g) ( 1.0 × 10 − 3 m / s) = 9.1 × 10 − 34 k g ⋅ m / s, Δ x = ℏ 2 Δ p = 5.8 c m. eric keating chiropractic

WebMay 1, 2024 · The angular momentum equation. Physics also features angular momentum, L. The equation for angular momentum looks like this: The angular momentum equation features three variables: L = angular momentum. / = the moment of inertia. W = the angular velocity. Note that angular momentum is a vector quantity, … WebThe net force exerted on the object at every moment, if we're decreasing the radius very slowly (we don't need to, its just to make it simpler), is mv²/r, the centripetal force. So, the work done will be W = -∫F.dr (from r1 to r2) = -∫mv²dr/r = -m.∫ (v1.r1)².dr/r³ (from the condition v.r is constant, we have v.r =v1.r1 ---> v² = v1²r1²/r²) WebMomentum Formula Momentum is another measurement of the vector. Momentum and the velocity both are in the same direction. Scientists do the calculation of the … find ppp recipients
