Centripetal force of a rubber bung essay sample aim : to get any object to move in a circle you have to apply a force to it methods : with your experiment you don't mention anything about controlling or measuring the force. David bednar physics 2a laboratory report lab 6: centripetal force and torque newton's 2nd law (fnet = ma) applies for the case of uniform circular motion where the object is acted upon by a force directed to the center of the circular motion, the centripetal force. Students when they think the water will fall out (the point at which the force of gravity is greater than the centripetal force) • watch clip 46 in which dallas demonstrates the role of air resistance.
In this experiment when the rubber bung is moving in a circular motion and the string it is tied to moves neither up or down a constant radius is being maintained for this to be true the centripetal force must equal the gravitational force hence. In a uniform circular motion, the object experiences a centripetal acceleration and centripetal force when an object of mass m is made to travel in a circular motion at constant linear speed v when an object of mass m is made to travel in a circular motion at constant linear speed v. Lab 5 - uniform circular motion introduction if you have ever been on an amusement park ride that travels in a curved or circular path, then you have experienced a force, called a centripetal force, pushing you into the ride.
A student performing a centripetal force experiment whirls a rubber bung attached to one end of a string which passes through a glass tube with smooth openings, and has a weight w hanging at its other end. centripetal force on a pendulum objective to measure centripetal force exerted on a pendulum using the force sensor bob and in so doing compare this value determined by force calculations based on the height of the pendulum theory newton's laws of motion are the basis for this experiment. Centripetal force is defined as an inward force on a body that causes it to move in circles centrifugal force is defined as an outward force on a body that appears real to the body rotating in a circle, however, it is fictitious (fake. Uniform circular motion - posted in science projects and homework: hi, we did the uniform circular motion experiment in school a few days ago in which we tied a rubber stopper to a string and swung it in a horizontal circle overhead. By keeping the angular speed of the rubber bung constant and considering the equilibrium of all the applied forces in the system, the theoretical value of the centripetal force f is calculated as follows: f = mv2/r or f = mr 2 where v and are the linear and angular speeds of the object respectively.
The centripetal force apparatus is designed to rotate a known mass through a circular path of known radius pick up a circular motion worksheet this lab will allow us to examine the relationship between mass. For example, to make a rubber bung travel around in a circular path on the end of a string, there must be a force acting towards the centre of the motion the force acting towards the centre of the motion is called a centripetal force. In this experiment, the centripetal force is the restoring force of a stretched rubber band with one end attached to the shaft of a dc permanent-magnet motor powered by your lvps and the other end attached to a # 6-32 nut.
In short the person swinging the bung would have more control over the four factors which i earlier identified, size of radius, mass of the bung, speed of the bung and the centripetal force, only if the person is swinging the bung around in a circle, horizontally. The weight mg of the rubber bung would contribute to the centripetal force of the circular motion also, the magnitude and direction of the weight of the bung is changing with time. 7 the diagram shows the apparatus used by two students to find out how the centripetal force acting on an object affects the speed of the object rubber bung.
Centripetal force by: alexander jones abstract in this experiment newton's first and second laws of motion were used to study and verify the expression for the force, f, to be provided to mass, m, to execute circular motion. There is one question proposed by my teacher when doing the whirling bung experience, investigate centripetal force the questoin is describe qualitatively how the angle between the vertical line and the string change when the rubber bung is whirled faster and faster. Centripetal acceleration newton's first law of motion states that each body moves at a constant speed in a straight line unless a net external force acts. Physics lab report impulse essay impulse and momentum lab part i: as the first lab of the physics 2 curriculum, our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class.
