Question

define centripetal force & escape velocity​

Answer 1

Answer:

A centripetal force (from Latin centrum, "center" and petere, "to seek"[1]) is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Isaac Newton described it as "a force by which bodies are drawn or impelled, or in any way tend, towards a point as to a centre".[2] In Newtonian mechanics, gravity provides the centripetal force causing astronomical orbits.

¹✓ Centripetal force is the component of force acting on an object in curvilinear motion which is directed toward the axis of rotation or centre of curvature.

The unit of centripetal force is Newton.

²✓ Escape velocity the lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
