Experiment 3 - Uniform Circular Motion

Question 1

a motion in which an object is
traveling along a circular path at a constant velocity

Answer 1

Uniform Circular Motion

Question 2

It is responsible for the change in the velocity’s direction, always directed towards the center of the circular path. and ensures that the object stays in a circular path

Answer 2

Centripetal Acceleration

Question 3

Formula of Centripetal Acceleration

Answer 3

ac = V^2/r = rw^2

Question 3

the force that acts on an object moving in a circular path, directed towards the center of the circle or the axis of rotation. It keeps the object in a circular motion

Answer 3

Centripetal Force

Question 3

Formula of Centripetal Force

Answer 3

Fc = mac = mV^2r = mrw^2

Question 4

The time it takes to complete one revolution around the circle

Answer 4

Period (T)

Question 5

Formula of Velocity undergoing circular motion

Answer 5

V = 2πr/T

Question 5

Varying Radius Workflow

Answer 5

1. Set the radius of the string (vary)
2. Put centripetal force mass (constant) along the pulley
3. Adjust the pole to align with the mass
4. Adjust the orange disk
5. Remove the pulley and hanging 6. Rotate the apparatus

Question 5

Formula of Centripetal Force (using the formula of velocity undergoing circular motion)

Answer 5

F = 4π^2mr/T^2

Question 6

Varying Force Workflow

Answer 6

1. Set the radius of the string (initial)
2. Put centripetal force mass (vary) along the pulley
3. Adjust the pole (initial)
4. Adjust the orange disk
5. Remove the pulley and the hanging mass
6. Rotate the apparatus
