When are the displacement velocity and acceleration equal to zero for the motion of a mass on a spring?
Displacement and acceleration are zero at the instant the mass passes through
its "rest" position ... the place where it sits motionless when it's not bouncing.
Velocity is zero at the extremes of the bounce ... where the expansion and compression
of the spring are maximum, and the mass reverses its direction of motion.

What are some common strategies for solving physics spring problems?
Common strategies for solving physics spring problems include using Hooke's Law (F -kx) to calculate the force exerted by the spring, applying conservation of energy to analyze the motion of the spring, and using the equations of motion to determine the displacement, velocity, and acceleration of the spring. Additionally, understanding the relationship between the spring constant (k) and the stiffness of the spring is crucial in solving these types of problems.
Is the acceleration of a particle moving with simple harmonic motion inversely proportional to the displacement of the particle from the mean position?
Acceleration is directly proportional to displacement in simple harmonic motion.There are perhaps two good explanations for this, one technical and one intuitive.First let us define simple harmonic motion.When a particle moves in a straight line so that the displacement of the particle with time is exactly given by a simple sine (or cosine) of time, then that it is simple harmonic motion.For example: x=A sine (w t) .Answer 1: (In two steps)(a) If we know position as a function of time, we know velocity is the time rate of change of position.v = w A cosine (w t)(b) If we know velocity as a function of time, we know acceleration is the time rate of change of velocity.a = -w2 A sine (w t)* So, acceleration is proportional to displacement, and a(t)=-w2 x(t).Answer 2: (In three steps)(a) Simple harmonic motion occurs when a mass on an ideal spring oscillates.(b) From Newton's laws, we know that acceleration is directly proportional to force.a=F/m(c) We know the force of an ideal spring is proportional to displacement (F=-kx).* So, acceleration is proportional to displacement, and a(t)= -k/m x(t).(This also tells is that w2 =k/m.)As a result, "acceleration is directly proportional to displacement in simple harmonic motion."
Define simple harmonic motion . prove that vibrating motion of mass attached to spring is Simple harmonic motion?
Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement from equilibrium and acts in the opposite direction. In the case of a mass attached to a spring, the motion is simple harmonic because the restoring force (provided by the spring) is directly proportional to the displacement from equilibrium (Hooke's Law) and acts in the opposite direction to the displacement, resulting in a sinusoidal motion.
Why is displacement directly proportional to acceleration?
Acceleration is given by the equation v-u/t, whereby v is the final velocity of a body, u is the initial velocity and t is the time. So for there to be acceleration, there has to be a change in initial velocity (the starting speed of the body) and the final velocity of the body or if there is no change it would be 0/t and hence the acceleration will be 0. And we know that with a change in speed there has to be a change in displacement i.e. s=d/t. So to sum all this up with an increase in acceleration there is an increase in distance. But this is a very tricky question because you asked about displacement and since displacement is a vector quantity, it has both magnitude and direction. So if a body accelerates forward, then its acceleration is directly proportional to its displacement. However, if the body stops and starts accelerating backwards, it becomes a whole new different story. Given that displacement has direction, if the body moves backwards, then the displacement will be negative, but the acceleration positive. So displacement is directly proportional to acceleration ONLY when a body is moving forwards, but displacement is indirectly proportional to acceleration when a body is moving backwards from it's point of rest. But for distance, given that it is a scalar quantity, it only has magnitude so it is not affected by the direction of movement of the body. So distance is directly proportional to acceleration when a body is moving both forwards and backwards.
What is the relationship between displacement and time?
There is no direct relationship between the two. Newton's Second Law, though, tells you how the VELOCITY of an object will change when a force is applied. The law - as it is usually quoted - says:F = ma Solving for acceleration: a = F/m So, the acceleration of an object will depend on the force. If you integrate this equation twice, you get the displacement - but the integration will also give you two arbitrary integration constants, meaning that you need to know the initial conditions (initial position, and initial velocity).

What happens to velocity if spring length is doubled?
If the spring's length is doubled, the spring constant is unchanged, and the velocity will remain the same in simple harmonic motion with a spring. The period of oscillation will change, as it is affected by the spring constant and mass of the object.
For a mass hanging from a spring the maximum displacement the spring is stretched or compressed from its equilibrium position is the systems?
The amplitude of the oscillation, which is the maximum displacement from the equilibrium position, is determined by the mass of the hanging object and the spring constant. The maximum displacement occurs when the object is released from its initial position and the system is in simple harmonic motion.
What employees a weight and a wire to detect horizontal movement?
An accelerometer is a device that can detect changes in velocity, orientation, and acceleration by measuring the change in electrical capacitance due to movement. It typically consists of a weight attached to a spring and a wire that measures the resulting displacement when the sensor moves horizontally.
What should be the spring constant k of a spring designed to bring a 1200 kg car to rest from a speed of 95 kph so that the occupants undergo a maximum acceleration of 4.0 g?
To find the spring constant k, we first calculate the deceleration needed to bring the car to rest from 95 kph using a = (v^2 - u^2) / (2 * s), where u is initial velocity, v is final velocity, s is displacement. Converting 95 kph to m/s, we get u = 26.39 m/s. We then use the maximum acceleration of 4.0 g to find the deceleration, a_max = 4.0 * 9.81 m/s^2. Finally, we can calculate the spring constant k by equating F_spring = m * a = k * x, where x is the displacement and solve for k.
How do you calculate velocity of a box attached to a spring?
some basic physics will tell you that the mass of the box times acceleration due to gravity times the height of the box above the ground, minus the force of the spring or the spring constant times the distance the spring stretches will equal .5 times the mass of the box times the velocity squared mgh-kx=.5mv2
Why can a mass spring system oscillate with simple harmonic motion when compressed?
A mass-spring system can oscillate with simple harmonic motion when compressed because the restoring force from the spring is directly proportional to the displacement of the mass from its equilibrium position. This results in a periodic back-and-forth motion of the mass around the equilibrium point.
