Chap 11&12 Flashcards
Two equipments used in Exp 11
Hooked Mass & Centripetal Force Apparatus
Object moves in a circulat motion w constant speed
Uniform Circular Motion
Acceleration of an object in UCM
Centripetal Acceleration
Acceleration is always inward/ to the center
Centripetal Acceleration
Inward force of an objct in UCM
Centripetal Force
To and fro motion of objects
Vibratory Motion
Force needed to deform a spring
Elastic limit
Relationship of Force & Elongation
Always opposite to each other
Relationship of spring & mass
Directly proportional
Restoring force is directly proportional to the displacement away from the equilibrium
Simple Harmonic Motion
Period^2 &mass relationship?
Directly proportional
K1 and k2 have?
Equal values
Motion repeats itself regularly at equal time intervals
Periodic Motion
Simplest type of vibration or periodic motion
Simple Harmonic motion
What disturbs a vibration on the spring?
External force such as air resistance / intermolecular friction
Examples of Vibratory Motion
Vibrations of a speing or rubber band w a heavy load at one end, motion of pendulum displaced from its equilibrium position, turning balance of a wheel and vibration of a tuning fork
The motion that repeats itself regularly at equal intervals of time
Periodic motion
May be illustrated by the vibration or oscillation of a coiled spring w a load at one end, displaced a little vertically from its equilibrium position
SHM
Motion for w/c the restoring force is directly prop to the displacement away from the equilibrium position
SHM
Indicates stiffness of a spring wire or bar
Force constant

How many trials are there in exp 12 a?
5 trials
How many grams are used in Exp 12 A?
30g each trial
