![]() 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. \(\displaystyle F_p=(26.0 kg+32.0 kg+12.0 kg)(9.80m/s^2)=686 N\)Ģ5.The learning objectives in this section will help your students master the following standards: ![]()
