Gravity,
At any instant time the restoring force is the component of gravity acting parallel to the direction of the motion.
FRiction
is called the centripetal force
Compressional Stress
thermal convection is the primary force that cause the sea floor to spread
The force of the water hitting what ever is below it causes erosion
Actually, the period of a pendulum does depend slightly on the amplitude. But at low amplitudes, it almost doesn't depend on the amplitude at all. This is related to the fact that in such a case, the restoring force - the force that pulls the pendulum back to its center position - is proportional to the displacement. That is, if the pendulum moves away further, the restoring force will also be greater.
External force or you can say deformation force causes spring to stretch and restoring force is developed due to introduction of restoring strain in spring to restore in its original shape.
No, a torsional pendulum works with the restoring force provided by the elasticity of the support rod, or (in clocks and watches) by the spring on the balance-wheel.
Restoring force, in a physics context, is a variable force that gives rise to an equilibrium in a physical system. If the system is perturbed away from the equilibrium, the restoring force will tend to bring the system back toward equilibrium.
The string that the 'bob' hangs from is a fixed length. So when the bob is off center and over to one side, it must be a little higher than when it's hanging straight down. The restoring force is the force of gravity that pulls it back down to the center.
A pendulum is an object that is attached to a pivot point so it can swing without friction. This object is subject to a restoring force that will accelerate it toward an equilibrium position. When the pendulum is displaced from its place of rest, the restoring force will cause the pendulum to oscillate about the equilibrium position. In other words, a weight attached to a string swings back and forth.A basic example is the simple gravity pendulum or bob pendulum. This is a weight (or bob) on the end of a mass less string, which, when given an initial push, will swing back and forth under the influence of gravity over its central (lowest) point.The regular motion of pendulums can be used for time keeping, and pendulums are used to regulate pendulum clocks.
restoring force
A pendulum is affected by the force of gravity.
Simple harmonic motion, In mechanics and physics, is a type of periodic motion where the restoring force is directly proportional to the displacement. A good example of this is a pendulum.
no force does not effect the pendulum as it depends upon the oscillations.
When a force is applied on a string, a restoring force is developed in it in opposite direction of external force.This restoring force of string is tension.
a pendulum is not only an unbalanced force it also is a "swinger" that swings in a back and forth motion because of this "force"
