Physics experiment, five uniform circular motion

Procedure step one

Placed two of the 100 g masses in each carriage and adjust the height of the four sensor so that the sliding carriage will move in a circle of roughly 10 to 15 cm

What is used?

A template not logger pro

Command space then search UCM

Procedure step two

Spin until force says 6 to 8 And then stop spinning and hit record

Procedure step three

Analyze your graph by applying a linear fit to your data

Radius of rotation

10 cm or 0.1 m

Mass placed in sliding carriage

200 g or 0.2 kg

Does your data support the prediction that radio force depends on the square of the rotation speed

Yes, because the graph is linear

What quantity is described by the slope of the fit to the F versus V squared graph

m over r

For force versus mass, repeat the same procedure at the same radius first using

Just one 100 g mass in each carriage and then using all three masses

The fit coefficient of the force versus mass is the

Slope of linear fit

The calculated mass of force versus mass is

The fit coefficient, but move decimal left one

Intercept of mass versus number graph

0.08

What does this intercept represent and how does your value compared to other groups?

The intercept represents the mass of the cart and the value is lower compared to other groups

Four force versus radius you’ll use the same procedure, but you will

Keep the mass constant and vary the radius of the rotating carriage

Four force versus radius placed two or three of the

100 g masses in each carriage and make sure to record the radius of the signing carriage, accurately into set the radius parameter in logger pro

Four force versus radius the calculated data is

The inverse of the fit coefficient so one over the coefficient

Do you get a linear relationship with the force versus Radius

Yes, because the radius is being increased evenly

What physical object provided the necessary radial force to keep the sliding carriage moving in a circle and what type of force was this?

The string kept the carriage moving in a circle and is a tension force

What other types of forces could be used as radial forces?

Gravity, magnetic force, spring force friction

Describe one way this apparatus may be modified to use a different type of force one that you’ve listed above to make the sliding carriage movement a circle

We could add a spring instead of the string

For the force versus radius graph, what is the X axis and Y axis?

X axis – Radius

Y axis – calculated data

For the force versus mass graph, what is the X axis and Y axis?

X axis – number of masses

Y axis – calculated mass
