Why is acceleration not always constant?
Whenever there is a change in velocity, either due to a change in speed or a change in direction, there will be non-zero acceleration. Acceleration is not constant if the net force is not constant.
Does acceleration remains constant in simple harmonic motion?
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.
Why acceleration is constant in equations of motion?
The equation v – = v 0 + v 2 v – = v 0 + v 2 reflects the fact that when acceleration is constant, v – is just the simple average of the initial and final velocities. Figure 3.18 illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate.
What is the acceleration of a particle in simple harmonic motion?
The acceleration of a particle executing simple harmonic motion is given by, a(t) = -ω2 x(t). Here, ω is the angular velocity of the particle.
Is it possible to have an accelerated motion with constant speed explain?
Yes, it is possible to have accelerated motion with constant speed, when a body is moving in a circular path. The body changes its path so there is a change in direction (velocity) but its speed remains the same.
What does it mean when acceleration is constant?
Sometimes an accelerating object will change its velocity by the same amount each second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity.
Why acceleration is Max at extreme position in SHM?
Complete answer: The acceleration is the change in velocity with respect to me. If the velocity of the simple harmonic motion is maximum, the acceleration must be equal to zero. Therefore, the particle will have maximum velocity at the central position and minimum at the extreme positions.
Is the acceleration of a simple harmonic oscillator ever zero?
Yes, the acceleration of a simple harmonic oscillator is zero at the equilibrium point where the displacement is zero.
