It's the maximal magnitude of acceleration, which always positive. The actual acceleration is a vector, which can point in different directions, depending on the sign of it's components.pyman12 said:The equation I am taught is that maximum acceleration is (2*pi*frequency)^2 * amplitude, which is a positive value?
Oh I see, the book didn't mention that. Thanks.A.T. said:It's the maximal magnitude of acceleration, which always positive. The actual acceleration is a vector, which can point in different directions, depending on the sign of it's components.
Simple harmonic motion refers to the periodic back-and-forth motion of an object around a central equilibrium point, caused by a restoring force that is directly proportional to the displacement from the equilibrium position.
Simple harmonic motion occurs when an object experiences a restoring force that pulls it back towards the equilibrium position after being displaced. This force is usually caused by a spring or elastic material.
Maximum displacement in simple harmonic motion refers to the farthest distance an object moves from its equilibrium position during one cycle of motion.
The acceleration is positive at maximum displacement because at this point, the velocity of the object is changing from positive to negative, meaning it is accelerating in the opposite direction. This acceleration is caused by the restoring force pulling the object back towards equilibrium.
The amplitude, or maximum displacement, of an object in simple harmonic motion determines the maximum speed and acceleration of the object. A larger amplitude results in a larger maximum speed and acceleration, while a smaller amplitude results in a smaller maximum speed and acceleration.
