Acceleration is in the direction of the change in velocity in this case it points roughly toward the center of rotation. The direction of the instantaneous tangential velocity is shown at two points along the path. Ask students what would happen if you suddenly cut the string? In which direction would the object travel? Why? What does this say about the direction of acceleration? Ask students to give examples of when they have come across centripetal acceleration.įigure 6.7 shows an object moving in a circular path at constant speed. Demonstrate circular motion by tying a weight to a string and twirling it around. The sharper the curve and the greater your speed, the more noticeable this effect becomes. This fictitious force is known as the centrifugal force. Inside the car it appears as if you are forced away from the center of the turn. This isn’t an actual force that is acting on you-it only happens because your body wants to continue moving in a straight line (as per Newton’s first law) whereas the car is turning off this straight-line path. What you notice is a feeling of sliding (or being flung, depending on the speed) away from the center of the turn. If you hold the steering wheel steady during the turn and move at a constant speed, you are executing uniform circular motion. You experience this acceleration yourself every time you ride in a car while it turns a corner. Therefore, an object undergoing uniform circular motion is always accelerating, even though the magnitude of its velocity is constant. We know from kinematics that acceleration is a change in velocity, either in magnitude or in direction or both. Note that, unlike speed, the linear velocity of an object in circular motion is constantly changing because it is always changing direction. The simplest case of circular motion is uniform circular motion, where an object travels a circular path at a constant speed. In the previous section, we defined circular motion. Ask students to give examples of circular motion.

In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Circular and Rotational Motion, as well as the following standards:

(D) calculate the effect of forces on objects, including the law of inertia, the relationship between force and acceleration, and the nature of force pairs between objects.

(C) analyze and describe accelerated motion in two dimensions using equations, including projectile and circular examples.

The student knows and applies the laws governing motion in a variety of situations.

Thus you get the value of g in your lab setup.The learning objectives in this section will help your students master the following standards: Then take an average value of the four g values found. So in this case for four data sets, you will get 4 values of g. Substitute each set of period (T) and length (L) from the test data table into the equation, and calculate g.

Now for each of the 4 records, we have to calculate the value of g (acceleration due to gravity) Now see, how to calculate and what formula to use. Table 1: Recording the following data for 4 sets of string length (1) Time for 10 oscillations & (2) Period (T) Calculating g (acceleration due to gravity) Record the data in the table below following the instructions in the section above. Use appropriate formulae to find the period of the pendulum and the value of g (see below).Repeat step 4, changing the length of the string to 0.6 m and then to 0.4 m.Change the length of the string to 0.8 m, and then repeat step 3.Note: Divide the time by 10 to calculate the period of the swings, where the period is the time needed by the pendulum for one complete swing.

Use a stopwatch to record the time for 10 complete oscillations. Move the mass so that the string makes an angle of about 5° with the vertical.Measure the effective length of the pendulum from the top of the string to the center of the mass bob.Set up the apparatus as shown in the diagram:.
