This image depicts a simple physics experiment involving circular motion. The setup consists of a tabletop structure where an object, likely a weight or bob, moves in a circular path on the surface. It is connected by a string or rod to another object hanging below the table. **Key Elements:** 1. **Circular Path**: - The top object moves in a circular path, indicated by the dashed line. This represents uniform circular motion, where the object maintains a constant distance from the center. 2. **Connecting Rod or String**: - A rod or string connects the top object to a hanging weight. This connection allows the top object to rotate while maintaining the balance of forces due to tension. 3. **Hanging Weight**: - The weight hanging below the table provides tension in the string, influencing the top object's circular motion. It demonstrates concepts such as centripetal force and tension. This setup is typically used to study forces in circular motion, centripetal acceleration, and the relationship between mass, radius, and velocity in rotational systems.
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.
An air puck of mass 0.270 kg is tied to a string and allowed to revolve in a circle of radius 1.29 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of 1.00 kg is tied to it as seen in the figure below. The suspended mass remains in equilibrium while the puck on the tabletop revolves. What is the tension in the string? What is the force causing the centripetal acceleration of the puck? What is the speed of the puck?
