A 3.59 kg ball is held at rest exactly 3.7 meters in the air. Assume their is no spring in this problem. A. How much gravitational potential energy does the ball currently have? B. How much kinetic energy does the ball currently have? C. How much total mechanical energy does the ball have currently? Joules Joules |Joules The ball is than allowed to fall to the ground. As the ball falls It gravitational potential energy gets converted into Kinetic Energy. The moment before hits the ground all of its energy is in the form of kinetic ener D. How much G.P.E does the ball have the moment before it hits the ground? E. How much kinetic energy does the ball have the moment before it hits the ground? F. what is the ball's speed the instant before it hits the ground? Joules Joules m/s
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.
