Motion
Examples of oscillatory motion
vibrating strings, swinging of the swing,etc.
The time taken for one complete oscillation
Period
three main types of Simple Harmonic Motion
Damped Oscillation, Forced Oscillationn, Free Oscillation
What is a pendulum?
any mass suspended on a string, rope, or other arm that can swing back and forth
The speed and direction of an objects motion is
Velocity
Examples of periodic motion
motion of hands of the clock, motion of planets around the sun etc.
Unit of measurement of amplitude
Meter
Theis type of oscillation possesses constant amplitude and period without any external force to set the oscillation. Ideally, it does not undergo damping.
The free oscillation
The period of oscillation of the pendulum depends on its ...
length
Speed, Velocity, and Acceleration all have this in common
Motion
the to and fro motion of the body about its fixed position
Oscillatory motion
The number of cycles\oscillations per second
Frequency
What is called forced oscillation.
When a body oscillates by being influenced by an external periodic force
When is the velocity of the pendulum greatest?
At the bottom of the swing.
Why are we always in motion?
The earth is always moving!
the motion that repeats itself after fixed intervals of time
Periodic motion
Unit of measurement of Frequency
Hertz
The oscillation that fades with time
damped oscillation
How could you increase the amount of time that it takes for the pendulum to make a full swing?
Increase the length of the pendulum.
What would be a good reference point to determine if the EARTH is moving
The Sun, moon, stars
It is the simplest form of oscillatory motion which all of us come across in our day to day life. It is an oscillatory motion in which retarding force proportional to the amount of displacement of an object from an equilibrium position.
Simple Harmonic Motion
Maximum displacement from the mean position
Amplitude
two types of damping
Natural Damping, Artificial Damping
The period of oscillation of a simple gravity pendulum depends on 1)... and 2)...
the length of the pendulum and on the magnitude of the gravitational acceleration.
Energy of motion
kinetic motion
