Question
Consider an object moving In a circular path with a constant speed. Which one of the following statements is correct concerning the direction of the acceleration of the object? The acceleration Is directed toward the centre of the circle. The acceleration is directed along the direction of motion. The acceleration is directed away from the centre of the circle. Consider an object moving in a circular path with an increasing speed Which one of the following statements is correct concerning the direction of the acceleration of the object? The acceleration has a radial component and a component directed along the direction of the velocity. The acceleration has a radial component and a component directed opposite to the direction of the velocity. The acceleration has only a radial component. Consider an object that is moving in a circular path at constant speed. The direction of the vector sum of all the forces acting on the object isExplanation / Answer
1.
if the speed of the object in circular motion is constant, the acceleration must be point toward the center of its circular path.
2.
If the velocity is decreasing or increasing, the acceleration has two components one is tangential and other one is radial. The tangential acceleration always point in motion of the body [or tangent to the path] and the radial component is pointed toward the center of the circlular path.
3.
The net force does not, if the net force on the object iszero, it must be move in a straight line. This means that the net force always toward the center of the circular path.
