C1 Notes

Oscillation

a movement around a central point

they will stop

What will happen to real world oscillating systems eventually?

Isochronous

oscillation repeats, taking the same repetition time, no matter its size

Equilibrium

when an object that could oscillate is stationary

increases

What happens to displacement as it moves away from the equilibrium?

decreasese

What happens to displacement as it moves towards equilibrium?

reverses and begins to increase again until it reaches another equal but opposite maximum

What happens to displacement when object reaches its maximum?

Amplitude

the maximum displacement from the equilibrium

Period

time for one complete cycle of oscillation

Frequency

number of complete oscillations per second

Phase

measure of the position of an oscillation within its cycle

Restoring force

provided by the elastic force of the spring

Restoring force

a resultant force of gravity and the tension of the suspension

Harmonic oscillators

period of oscillation is independent of amplitude

the overshoot of equilibrium

With harmonic oscillators, what does enertia cause when it is in motion?

return it to equilibrium

Force is acting on the oscillating object to do what?

towards equilibrium

In simple harmonic motion, what direction is acceleration in?

opposite direction

In Simple Harmonic motion, what is the direction of acceleration in terms of displacement?

amplitude

The radius in circular motion relates to what in simple harmonic motion?

phase

The angular displacement in circular motion relates to what in simple harmonic motion?

angular frequency

The angular velocity in circular motion relates to what in simple harmonic motion?
