For a simple pendulum, clearly distinguish between v (the angular speed) and v (the angular frequency). Which is constant and which is variable?

What if we wanted to use a conical pendulum to tell time? It would be great if we had a pendulum that made one revolution every hour. How long of a pendulum, though, would we need for this if the angle of the pendulum was a mere 2.00° from the vertical?

A simple pendulum with a length of 1.73 m and a mass of 6.74 kg is given an initial speed of 2.36 m/s at its equilibrium position. (a) Assuming it undergoes simple harmonic motion, determine its period (in s). (b) Determine its total energy (in J). (c) Determine its maximum angular displacement (in degrees). (For large v, and/or small /, the small angle approximation may not be good enough here.) (d) What If? Based on your answer to part (c), by what factor would the total energy of the pendulum have to be reduced for its motion to be described as simple harmonic motion using the small angle approximation where 0 ≤ 10°?

A scientist wishes to determine the acceleration of gravity on the surface of the planet Nos'Kere by experimenting with a pendulum. The length of the pendulum is 3.2 m, and the period of the pendulum is 2.3 s. unit
