Â· Prokaryotic cells that are present in the soil, air, water and in many humans body parts, such as the skin. 1  Reproduce by binary fission so that within a short time, the host can contain thousands of bacteria.  Produce toxins often as waste products, which harm the host.
The car is changing direction because of a force (supplied by friction between road and tires) directed toward the center of the curve. That is the centripetal force, which is always directed toward the center of the curve. When you swing a weight around your head at the end of a string, your hand supplies the centripetal force to keep the weight moving in a circle. Back inside the car, you feel a force pushing you AWAY from the center of the curve. That force is called centrifugal force, which is always equal in magnitude but opposite in direction from centripetal force. Answered by: Paul Walorski, B.A. Physics, Part-time Physics Instructor.
The acceleration of the object is dependent upon this velocity change and is in the same direction as this velocity change. The acceleration of the object is in the same direction as the velocity change vector; the acceleration is directed towards point C as well - the center of the circle. Objects moving in circles at a constant speed accelerate towards the center of the circle.
