im currently first year medicine.. cam anyone explain centripetal force and acceleration...with links perhaps with further explanation
do you understand forces and acceleration in general?
its a completely new concept
If you do not have a background concept of the 'laws of motion' then this is not a trivial topic. A body will remain in straight line constant velocity motion unless acted upon by a force. If acted upon by a force then the body will accelerate, and the equation relating the factors is F=ma where F = force m= mass of object and a = acceleration Travelling in a circle is NOT straight line... therefore in order for a body to move in a circle a force must act upon it. That force always act towards the centre of the circle, even though the motion is always tangential to the circle. i.e. the body does not move in the direction of the force. The acceleration does not result in a change of speed, but does change the velocity (i.e. the direction). Examples: Force of gravity acting towards centre of earth - on a satellite in circular orbit. Tension in a string causing a ball to whirl aroun when swung Friction on tyres pushing INWARDS as car turns in circular arc The force ON YOU in a fairground ride PUSHING you in (NOTE - this is NOT what you instinctively feel as a force pushing you out. There is no 'centrifugal' force, only the reaction to the centripetal force which pushes you in)
centripetal force is the force that experienced by an object in uniform circular motion and the acceleration towards the center is centripetal acceleration a=v2/r
It is the force that actually CAUSES circular motion - it is not an incidental experience. However - it seems the OP has lost interest.
