Question

1) what is moment of force ?
2) what is uniform circular motion​

Answer 1

1.The Moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis. This is different from the tendency for a body to move, or translate, in the direction of the force. ... It is defined as the product of the force (F) and the moment arm (d).

2.In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
