Detailed explanation-1: -A pendulum reaches its maximum velocity when the block is at its lowest point (the pendulum is vertical and pointing straight down). We can then use the expression for conservation of energy to determine the maximum height of the block.
Detailed explanation-2: -The lowest velocity, always zero, coincides with the pendulum’s farthest distance from the center of the earth.
Detailed explanation-3: -Q. Assertion :For an oscillating simple pendulum, the tension in the string is maximum at the mean position and minimum at the extreme position. Reason: The velocity of the oscillating bob in simple harmonic motion is maximum at the mean position.
Detailed explanation-4: -For a pendulum, the maximum speed is when the pendulum is at the bottom of its swing so x=0. The function for velocity of a pendulum is v=√x02-x2.
Detailed explanation-5: -In simple pendulum at lowest point tangential acceleration is zero.
