Distance between the centers of the two objects are the second object
The kinetic energy will be greatest at the bottom of the swing motion.
The potential energy will be greatest at the highest position of the swing.
Potential energy is the energy stored in an object or system due to the position or placement of its parts. However, it is not affected by the external environment of the object or system. Kinetic energy, on the other hand, is the energy of the particles of an object or system in motion.
In an oscillating pendulum, the potential energy and gravitational kinetic energy are constantly changing. The potential and kinetic energies are maximal at extreme and intermediate positions, respectively.

Answer:
The particles in the medium of a surface wave move neither longitudinal nor transverse, the particles of the medium in a surface waves undergo circular motion.
<u>Explanation:
</u>
<em>Surface waves are traveled along the surface of the oceans</em>, these particles undergo <em>circular motion these form ripples on the surface of the water. </em>The motion of the particles in the medium gradually decreases from surface to surface. <em>A surface waves are also called as circular waves as the particles of the medium move in circular direction.
</em>
The answer is
D. in a straightforward, objective manner
Answer:
64 J
Explanation:
The potential energy change of the spring ∆U = -W where W = work done by force, F.
Now W = ∫F.dx
So, ∆U = - ∫F.dx = - ∫Fdxcos180 (since the spring force and extension are in opposite directions)
∆U = - ∫-Fdx
= ∫F.dx
Since F = 40x - 6x² and x moves from x = 0 to x = 2 m, we integrate thus, ∆U = ∫₀²F.dx
= ∫₀²(40x - 6x²).dx
= ∫₀²(40xdx - 6x²dx)
= ∫₀²(40x²/2 - 6x³/3)
= ∫₀²(20x² - 2x³)
= [20x² - 2x³]₀²
= [(20(2)² - 2(2)³) - (20(0)² - 2(0)³)
= [(20(4) - 2(8)) - (0 - 0))
= [80 - 16 - 0]
= 64 J
