Presentation transcript:

SHM occurs when an object oscillates back and forth over the same path. Examples 1. 2.

1. Period, T, the time it takes to execute one complete cycle of motion.  Units: 2. Frequency, f, the number of cycles or vibrations per unit time.  Units: 3. Amplitude, A, the maximum distance traveled by an object away from its equilibrium position.  Units:

An object is attached to a spring and executes SHM with a period of 0.25 s. If the spring constant of the spring is N/m then what is the mass of the object?

A 1300 kg car is constructed on a frame supported by four springs. Each spring has a spring constant of 20,000 N/m. If two people riding in the car have a combined mass of 160 kg, find the: a) Period of the vibration of the car when it is driven over a pothole in the road. b) Frequency of the vibration of the car. c) How long does it take the car to execute 3 complete cycles?

A simple pendulum of length 2 m oscillates on earth. a) How many complete oscillations does it make in 5 min? b) What is the period of the pendulum on moon where the force of gravity is 1/6 that of earth?
