Why force is zero at mean position in SHM?

At mean position, the displacement of the particle is zero. Here, k is the force constant and x is the displacement from the mean position. Here, m is the mass of the particle and a is the acceleration. Therefore, the acceleration of the particle at mean position is zero.

What is maximum at mean position in SHM?

The maximum displacement of a particle executing SHM from its mean position is 2 cm and its time period is 1 s.

At what position the velocity of the bob of an oscillating simple pendulum is maximum and where is it minimum?

Once at position D, the bob will have a zero displacement and a maximum velocity. The velocity is greatest when the displacement is least.

What is mean position in SHM?

There will be a restoring force directed towards equilibrium position (or) mean position. In an oscillatory motion, the net force on the particle is zero at the mean position. The mean position is a stable equilibrium position.

Is the force ever zero if so at what point in the motion?

The restoring force in SHM must be proportional to the displacement away from the equilibrium position. So, every time the mass passes through the equilibrium position, the force is zero. In fact, it is the point where the force reverses direction, and must, therefore, pass through zero in order to reverse.

Which of the following variable has zero value at the extreme position in SHM?

1. Which of the following variables has zero value at the extreme position in SHM? Explanation: At the extreme position in SHM, the body comes to instantaneous rest. The force, and therefore acceleration, is maximum at this point according to the force eqn: F = -kx.

Why is velocity maximum when acceleration is zero?

Maximum velocity is reached when you stop accelerating, because this is when you can’t gain anymore speed, i.e. acceleration is zero. In other words the derivative of velocity is equal to zero. However, zero acceleration can also result in minimum velocity because you can’t lose any more speed.

What is the maximum possible velocity at lowest position for oscillation of a simple pendulum of length l What can happen to the motion if the velocity exceeds this value?

For oscillation of a simple pendulum max possible velocity at the lowest point =√3gl When the velocity exceeds √3gL but is less than √5gL , the bob leaves the vertical circle When upsilon =√5gL the bob will complete the vertical circle .

What is the maximum velocity of this pendulum?

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=ω√x02-x2. Angular velocity (ω) = 2π/T and T = √l/g.

What is mean position of Bob?

The Mean Position is the Position that is moderate between two other extreme positions. It is the Position of the Bob when the freely suspended Pendulum is at rest. position. Also velocity (v) is zero at extreme position, thus T is minimum at extreme position.
