Uniform Circular Motion
Warm up
1 Turn in your Hookersquos Law Lab report to the bin
2 Take out your elevators HW set A blank sheet of paper Something to write with A calculator
HW quiz will begin after I take attendance and
perform the tension demo from last class

Circular motion
Uniform circular motion pertains to objects moving at a constant speed in a perfectly circular path
Circles review How do you find the circumference of a circle Complete questions 1-2 of the class work worksheet
New vocabulary
Period T [measured in seconds] the time required to travel once through a full cycle in UCM this means time required to travel one full circle
Frequency f [measured in Hertz Hz] the number of complete cycles an object completes per a given
amount of time in UCM this means the number of complete circles an object completes in 1 second

If I swing a ball around on a string and let it go Which way will it fly
Centripetal vs centrifugal
There is no such thing as a centrifugal force
The fake centrifugal force is a perceived force It feels like you are being swing outward but the opposite is true
In order for an object to travel in a circle it requires a net force towards the center of the circle This is the centripetal force

Horizontal circles
For simplicity we will start by looking at cases in the horizontal plane with only one force providing the centripetal force

Vertical circles
If an object is being swung in a vertical circle there are two forces acting tension and gravity
At the top tension and gravity act together to provide the centripetal force
At the bottom tension has to act against gravity to provide the centripetal force

G=667 x 10-11 Nm2kg2
Orbits
Gravity is supplying the centripetal force to keep planets satellites and moons in orbit
Satellites
A geosynchronous satellite is a satellite that orbits Earth with the same period and frequency as the rotation of the earth so it stays in the same location relative to the surface of the Earth
There is only one specific altitude that a satellite can
achieve this feat Mass of the earth 5975 x 1024 kg Radius of the earth 6371 x 106 m

Centripetal vs centrifugal
There is no such thing as a centrifugal force
The fake centrifugal force is a perceived force It feels like you are being swing outward but the opposite is true
In order for an object to travel in a circle it requires a net force towards the center of the circle This is the centripetal force

Do you feel more centripetal force for a sharper turn or a wider turn
Centripetal force
Horizontal circles
For simplicity we will start by looking at cases in the horizontal plane with only one force providing the centripetal force
Example problems 11 12 13
Simulating gravity in outer space
If there is no force of gravity in outer space how can a space ship lsquofakersquo a force of gravity so people arenrsquot just floating around
Faking gravity
A rotating spaceship uses the normal force of the outer wall to give passengers lsquoapparent weightrsquo just like in an elevator
Example problems 14 amp 15
Vertical circles
If an object is being swung in a vertical circle there are two forces acting tension and gravity
At the top tension and gravity act together to provide the centripetal force
At the bottom tension has to act against gravity to provide the centripetal force

is a centripetal force when applied to planets
G=667 x 10-11 Nm2kg2
Orbits
Gravity is supplying the centripetal force to keep planets satellites and moons in orbit
Satellites
A geosynchronous satellite is a satellite that orbits Earth with the same period and frequency as the rotation of the earth so it stays in the same location relative to the surface of the Earth
There is only one specific altitude that a satellite can
achieve this feat Mass of the earth 5975 x 1024 kg Radius of the earth 6371 x 106 m
