# Physics lab circular motion

This motion is called uniform circular motion—motion in a circular path at constant speed since the velocity vector is changing in time, the object in uniform circular motion is accelerating. In this physics lab, we'll be examining the effect of centripetal force on an object moving in a circle by using a bucket filled with water. This lab activity will guide you through some of the important ideas we will encounter in circular motion you are to work you way through this at your own pace.

Friction is the unbalanced central force that is supplying the centripetal force necessary to keep the car moving along its horizontal circular path: f = f c = ma c since f = μn and n = mg on this horizontal surface, most problems usually ask you to solve for the minimum coefficient of friction required to keep the car on the road. The most difficult quantity (of mass, speed, and radius) to hold constant from trial to trial in an experiment is the speed of the object, so it is easiest to study the effect of speed on centripetal force, since it is relatively easy to hold the mass of the object and the radius of the circle constant. The following lab implementation was designed for use in my honors physics i class and only represents one method of analyzing the data provided in the video notice at the bottom of the opening screen that there is a drop down listing of different radii.

Lab 5: circular motion physics 193 fall 2006 5 • measure the time interval for the block to make ten trips around the circle • use the last two measurements and your knowledge of circles to calculate the block’s speed while traveling around the circle. With this lab students can investigate circular motion in a perfectly horizontal circle and at an angle the first of two experiments uses a rubber stopper and tube to create horizontal circular. If the cars actually travel through this turn in excess of 195 mph, or 87 m/sec, what would supply the additional centripetal force example #5: gravitation and satellites another major category of forces that produce uniform circular motion is gravitation. The purpose of this lab is to investigate the relationship between the speed of an object in uniform circular motion (ucm) and the centripetal force on the object.

Circular motion is motion in two dimensions characterized by a circular path since the direction of motion of an object following uniform circular motion is constantly changing, its linear velocity vector $\vec v$ also changes its direction, but not its magnitude $\|\vec v\|=v$ (remember that a vector has magnitude and direction. Is zero this motion is called uniform circular motion—motion in a circular path at constant speed since the velocity vector is changing in time, the object in uniform circular motion is accelerating. This lab is designed to examine the relationships between the force, mass, and radius of an object moving in a circular path and the velocity it must maintain to stay in that circular path this lab is an idealized version of the string through a tube lab that students have been doing for years.

## Physics lab circular motion

This lab is based on the video entitled motion in a circle from the direct measurement video project hosted at science education research center at carleton college (serc) the copyright for these videos belongs to school district 197 in mendota heights, minnesota. In this physics lab, we'll be examining the effect of centripetal force on an object moving in a circle by using a bucket filled with water, you'll be able to understand how the centripetal force acts to hold an object in a circular pattern.

• Phy 133 lab 5 - centripetal motion the purpose of this lab is to study uniform circular motion, and to determine the relationship between centripetal force $f_c$ and the period $t$ of the rotational motion.
• Circular motion to examine what happens as you change three quantities: the mass, the length of the string, and the velocity that is, what happens to the centripetal force when you change v, r, and m it makes sense to divide this lab into three parts that will examine each of these.

Lab 5: circular motion physics 193 fall 2006 1 lab 5: circular motion i introduction the lab today involves the analysis of objects that are moving in a circle. • this lab requires you to swing masses on the end of a string with uniform circular motion to examine what happens as you change three quantities: the mass, the length of the string, and the velocity. The physics classroom » multimedia studios » circular, satellite, and rotational motion » uniform circular motion uniform circular motion uniform circular motion can be described as the motion of an object in a circle at a constant speed.
