If a steel ball is placed at the lowest point of a smooth, curved bowl and slightly displaced, it moves back and forth. When the ball is displaced, gravity and the normal force of the bowl create a restoring force directed toward the equilibrium position. The acceleration of the ball is proportional to its displacement, … Read more
Vibration: A complete to-and-fro motion of an oscillating object around its equilibrium position. One full cycle of motion is called one vibration. Amplitude (A): The maximum displacement of an oscillating object from its mean position. It determines the energy of the oscillation. Time period (T): The time required to complete one full oscillation. It is … Read more
Consider a mass attached to a vertical spring with a force constant . When displaced from its equilibrium position, the restoring force acts in the opposite direction, according to Hooke’s Law: F= -kx Applying Newton’s second law, ma= -kx a= -kx/m Since acceleration is proportional to displacement and directed toward the equilibrium position, the motion … Read more
Oscillation refers to the repeated motion of a body about a fixed point or equilibrium position. It can be periodic or non-periodic, depending on whether the motion follows a regular time pattern. Simple Harmonic Motion (SHM) is a special type of oscillatory motion in which the restoring force acting on the body is directly proportional … Read more
Waves diffract the most when their wavelength is comparable to or larger than the size of the obstacle or opening they pass through. Related Questions: Give an example of vibratory motion which is not simple harmonic motion. Give a reason for your selection. At the extreme position, velocity is zero but acceleration is maximum in … Read more
Water waves refract because their speed changes when moving from one depth to another, causing a change in wavelength and direction. Related Questions: Give an example of vibratory motion which is not simple harmonic motion. Give a reason for your selection. At the extreme position, velocity is zero but acceleration is maximum in simple harmonic … Read more
Frequency and time period are inversely related. If the time period decreases, frequency increases. Wave speed remains the same if the medium does not change. Related Questions: Give an example of vibratory motion which is not simple harmonic motion. Give a reason for your selection. At the extreme position, velocity is zero but acceleration is … Read more
The time period depends on gravitational acceleration, which is slightly lower at higher altitudes like Murree. To make it the same in Karachi, the length of the pendulum should be slightly increased. Related Questions: A simple pendulum has a time period “T”. What will happen to its time period if its thread length is shortened … Read more
The spring with a higher spring constant ‘k’ vibrates faster because the time period T≈2π√m/k is inversely proportional to ‘k’. Related Questions: Give an example of vibratory motion which is not simple harmonic motion. Give a reason for your selection. At the extreme position, velocity is zero but acceleration is maximum in simple harmonic motion. … Read more
The time period remains the same because it depends on the length of the string and gravitational acceleration, not on the mass or material of the bob. Related Questions: Give an example of vibratory motion which is not simple harmonic motion. Give a reason for your selection. At the extreme position, velocity is zero but … Read more
