... 1. The object must be moving in a circle with a fixed radius and the object must be moving at a constant speed. 2. While speed is a directionless quantity, velocity is a vector and therefore any change in direction indicates a change in velocity. 3. Newton’s first law states that a body moving at a ...

... What happened to the lines? There are traffic lights at this intersection, and each day hundreds of cars stop just to the left of the fines. When the light turns green, the cars accelerate to the right (Fig. 2). To achieve this acceleration, the car tires exert a backward force on the road (to the ...

6.3 Apparent forces in circular motion
... As an object turns, another body inside that object but not connected to it will want to keep moving straight by inertia (Newton’s First Law). The result is that the object runs into the body. To the body, it feels that there is an outward force acting, but this force, called Centrifugal force, does ...

... REASONING AND SOLUTION The sailboat moves at constant velocity, and, therefore, has zero acceleration. From Newton's second law, we know that the net external force on the sailboat must be zero. a. There is no work done on the sailboat by a zero net external force. b. Work is done by the individual ...

... The acceleration of an object is its rate of change of velocity, not just speed. For example a car going around a corner at a constant speed of 25 mph is accelerating, and you as a rider in the car feel that acceleration. The seat of the car must push on your body to make it accelerate. Turning left ...
