Force

A uniform circular motion is an accelerated motion. Explain it. State whether the acceleration is uniform or variable? Name the force responsible to cause this acceleration. What is the direction of force at any instant? Draw diagram in support of your answer.

When an object goes on a circular path at a constant speed, the amount of its velocity does not change; it just changes its direction. As a result, it's referred to as consistently accelerated motion.

A, B and C are the three forces each of magnitude 4N acting in the plane of the paper as shown in Figure. The point O lies in the same plane. (i) Which force has the least moment about O? Give a reason. (ii) Which force has the greatest moment about O? Give a reason.

(i) Moment of force= Force x Perpendicular distance, as we all know. Because the perpendicular distance between vector C and point O is the shortest, As a result, vector C will have the smallest...
