0 velocity
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum
The instantaneous acceleration of the particle is equal to 0 when the velocity of the particle is at a maximum or minimum. This occurs at the points on the graph where the slope of the velocity-time graph is horizontal or the velocity reaches a peak or trough.
The statement is incorrect. The maximum displacement of a particle from its equilibrium position in a wave is known as the amplitude of the wave, not the amplitude of the particle itself.
At the extreme end of vibration, the particle velocity is at its maximum value. This occurs when the particle reaches the peak amplitude and changes direction. It then slows down to a stop before moving in the opposite direction.
The maximum displacement of a particle of a wave is called the amplitude. It refers to how far the particle moves from its equilibrium position as the wave passes through it.
Amplitude measures the maximum displacement from the equilibrium position of a wave or oscillation. In physics, it refers to the maximum value of displacement, velocity, or acceleration of a vibrating object or wave. A larger amplitude indicates a greater energy content in the wave.
Acceleration is a vector, so it has both magnitude and direction.A particle in the simple harmonic motion, x = a cos(2t), has an acceleration that varies between positive and negative extremes (+4a and -4a) at the end points of its motion and has zero acceleration as it passes through its center of motion.Here is the mathematics.Position ' x ' = a cos(2t)Velocity ' v ' = dx/dt = -2a sin(2t)Acceleration = dv/dt = -4a cos(2t)The minimum instantaneous magnitude of acceleration is zero,and its most negative instantaneous value is [ -4a ].
If you record your voice for example you have a certain amplitude and a certain velocity. If you listen to the recording and slow it down your velocity wil slow down and the amplitude will stretch wich will make it sound lower.
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.
The formula to calculate maximum speed is: maximum speed = square root of (2 * acceleration * distance). This formula takes into account the acceleration and distance traveled to determine the maximum velocity attainable.
From Figure 1, the velocity-versus-time graph of a particle in simple harmonic motion, we can infer the amplitude, period, and phase of the motion. The amplitude is the maximum velocity reached by the particle, the period is the time taken to complete one full cycle of motion, and the phase indicates the starting point of the motion within the cycle.
The maximum displacement upwards is given by the equation y=-vxv/2g. At the peak, the value of velocity is said to be v=0.
