Why is acceleration opposite to displacement in simple harmonic motion?

Acceleration in SHM When the displacement is maximum, the acceleration is maximum, because the spring applies maximum force; the force applied by the spring is in the opposite direction as the displacement.

What is the direction of acceleration of a simple pendulum?

(A) : During the oscillation of simple pendulum the direction of its acceleration at the mean position is directed towards the point of suspension and at extreme position it is directed towards the mean position.

Can acceleration and displacement be in the same direction in simple harmonic motion?

No displacement and acceleration can not be in the same direction.

Is acceleration always negative in SHM?

In simple harmonic motion, more a particle is away from its equilibrium, less its speed becomes. So the value of acceleration is always negative.

How are the acceleration and displacement related in simple harmonic motion?

An object is undergoing simple harmonic motion (SHM) if; the acceleration of the object is directly proportional to its displacement from its equilibrium position.

Is there acceleration in a pendulum?

The undriven pendulum involves two force vectors, by the string and by gravity, adding to cause the pendulum acceleration. The acceleration is the same direction as the net force. Even though the string tension and acceleration change, the motion remains in the plane defined by the string force and the gravity force.

What is the direction of velocity in simple harmonic motion?

At the equilibrium position, the velocity is at its maximum and the acceleration (a) has fallen to zero. Simple harmonic motion is characterized by this changing acceleration that always is directed toward the equilibrium position and is proportional to the displacement from the equilibrium position.

How are the direction of velocity and acceleration of a particle in SHM related to each other?

Acceleration in SHM It is velocity per unit time. We can calculate the acceleration of a particle performing S.H.M. The negative sign indicated that acceleration and displacement are in opposite direction of each other. Equation I is the expression of acceleration of S.H.M.

Which is always negative in SHM?

Direction of Force and acceleration is always opposite to Displacement. ∴ Dot product of Displacement with Force and displacement with acceleration will always be negative. Hence, Option (c).

Which of the following are always negative in a simple harmonic motion?

Here, Right side of the $x$ axis is considered positive for displacement and travelling towards the right is considered positive velocity. Note:Students usually get confused when resolving a vector into two parts.
