Thus, a swinging pendulum has its greatest kinetic energy and least potential energy in the vertical position, in which its speed is greatest and its height least; it has its least kinetic energy and greatest potential energy at the extremities of its swing, in which its speed is zero and its height is greatest.
The Tonga Trench is located at the tectonic boundary between the Pacific Plate and the Indian-Australian Plate.
It is an Oceanic trench that is located in the south-west Pacific Ocean. It is actually the deepest trench of the southern Hemisphere and the second deepest on Earth.
The smaller the displacement, the smallest restoring force it will create.
As seen from the figure given below, The spring system follows the equation,
F = -Kx
where, x is the displacement
F is the restoring force
k is the spring constant
If , K is kept constant, then,
F is directly proportional to the displacement but it acts in opposite direction due to negative sign.
