Question

37.
For a particle moving in a central
field:
(A)
The kinetic energy is a constant
of motion
(B)
The potential energy is velocity
dependent
(C)
The motion is confined in a
plane
(D)
The total energy is conserved​

Answer 1

Answer:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Answer 2

the motion confined in a plane
