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

Elevators Homework Quiz

Once you finish turn your answers into the top bin place the quiz worksheet in the bottom bin Pick up a circular motion worksheet

New Topic ndash Uniform Circular Motion

1 Have you ever heard of centripetal motion If so

explain

2 Have you ever heard of centrifugal force If so explain

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

Centripetal force

Centripetal force always points towards the center of the circle

lsquocentripetalrsquo means center seeking

The centripetal force is a NET FORCE The centripetal force is often a force of tension

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

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

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

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
