A horizontal disk rotates about a vertical axis through its center. Point Pis midway between the center and the rim of the disk, and point Q is on the rim If the disk turns with constant angula velocity, which of the followng statements about it are true? (There may be more than one correct choice.) Lutfen bir ya da daha fazlasını seçin O A The linear acceleration of Q is twice as great as the linear acceleration of P OB The linear acceleration of P is twice as great as the linear acceleration of Q OC The angular velocity of Q IS same as the angular velocity of P O D. Qis moving twice as fast as P. DE Pand Q have the same angular acceleration
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
