Lab: To determine the angle of an inclined plane.
1. Obtain a length of ticker tape which has been attached to the trolley as it rolled down
an inclined plane.
2. The timer has a frequency of 40 Hz (ie. 40 dots per second are created), each space

slope between 2 points = = Vavg.
If d vs. t graph
slope gives Vavg
PHYSICS SPH 4U
COEFFICIENT of FRICTION ( )
APPARATUS String, ramp, pulley, wooden block, 100 g mass, balance, large protractor or
angle measuring device, chalk, metre stick, stop watch or photo gate timer.
1. Set up the apparatus as shown above.
1. What is the centripetal acceleration of a locomotive traveling around a flat curve of
radius 250 m at a constant speed of 70 km/h?
2. What centripetal force acts on a girl, mass 40 kg, standing at the outer rim of a c
DERIVATIONS OF THE CONSTANT ACCELERATION EQUATIONS
By looking at the above graph and recalling that area under a velocity time graph is equal to displacement,
we can derive a very useful equation.
The Physics of an Amusement Park
Physics is heavily utilized when designers of amusement park rides create the ride. Many people
really enjoy going onto these rides but rarely think about what technology is incorporated. Your
assignment will r
You and a partner are to build from scratch a machine that demonstrates five different energy transformations.
There are no restrictions to the types of materials used but the machine cannot be any taller than 1.0 m and must be
no larger than 0.5

THIN FILM INTERFERENCE
Partial reflection and refraction happens
when light encounters a new medium
A change of phase occurs when light
reflects from an optically more dense
material (i.e. a higher index of refraction,

INTERFERENCE OF WAVES IN TWO
Wave interference is the phenomenon which occurs when two waves
meet while traveling along the same medium
Constructive interference is a type of interference which occurs at any
