# Centripetal and Centrifugal.

Extracts from this document...

Introduction

Physics

Centripetal and Centrifugal

Purpose:

A) To find out in which direction an object flies off, if it is spun and then released.

B) to investigate how the radius affects the speed of ta spinning object.

Background info:

Centripetal: force pulling/pushing an object away from the center.

Centrifugal: force pulling/pushing an object towards the center.

Inertia: matter continues in its state of motion.

Distance: the length between two points.

Radius: half the distance of a circle.

Materials: String, object and your hand

Hypothesis: A) I think it will go forward because the objects inertia takes over the centrifugal and centripetal forces after the string is released. Inertia continues in a line of motion.

B) I

Middle

1) Get an object.

2) Tie one end of the string to the object.

3) Take the end of the string that doesn’t have anything attached to it.

4) Start moving your hand in a circular motion and make the object spin.

5) Keep the object spinning at a constant force or speed.

6) Let go of the string and observe what happens.

Procedure B:

1) Do steps 1 – 5 in procedure A.

2) As the object comes around, place your finger half way of the radius.

3) Let the object spin around your finger.

4) Observe if the speed, after you put your finger, is the same, faster or slower than the speed when you were just spinning the object without you r. (no finger)

5) Record the Data.

Data/ Analysis

The object flew off forward after the spinning.

Conclusion

Before we performed the lab, I hypothesized that the object will go forward when the string is released because inertia takes over. For the second part I hypothesized that the smaller the radius, the faster it will go. I hypothesized this because the smaller the radius, the less distance the object will have to travel. This enables the object to move much faster when it is closer to the center. These hypotheses were correct.

As a final conclusion I can say that if an object is spun around and then released, then the object will fly off forward and  if the radius of the object is shortened then the object will move faster, for it has less distance to cover.

1. ## Factors affecting the speed of a trolley Travelling down a ramp.

The only way you can actually calculate the acceleration of the trolley is by using a ticker timer. After setting up the ticker timer, we then released the trolley, which then travelled down the ramp. After recording our results we analysed the ticker timer tape.

2. ## Factors affecting the speed of a trolley

Note: * stands for multiplication Potential Energy By using this formula we can see that as the height of the ramp increases so does the potential energy. This is because the mass, gravitational field and the height are all related and their combined product is the potential energy.

If a rock you drop accelerates down at 9.8 m/s2, scientists say the rock is in a "1 g" environment, [1 g = 9.8 m/s2 = 22 mph/s]. Any time an object experiences the pull equal to the force of gravity, it is said to be in a "one g" environment.

Hence we can find out the gravitation acceleration. Procedures 1. The clamp was fixed on the stand. 2. The optical pin with cork was fixed on the middle point of the stand by using plasticine. 3. The stand is fixed on the table firmly by using the G-clamp 4.
