harmyder said:Suppose body A has mass 2kg and body B has mass 1kg, i think spring will act on body A with force ##kx## and on body B with the same force, but i don't understand why? Why not ##kx/2##?
Sorry, what additional information should i provide?Nidum said:There is not enough information given in the problem statement for any definite answer to be arrived at .
Looks right to me.Eclair_de_XII said:I think Newton's Third Law explains this. The spring exerts a force ##kx## on ##B## and in turn, ##B## exerts a force ##-kx## on the spring. Then the spring transfers that force ##-kx## to ##A##, and in turn, ##A## pushes back on the spring with the force ##kx## which gets transferred to ##B## and so on and so forth. Can someone correct me on this or explain this more clearly so that he can understand?
Spring force is a type of conservative force that arises due to the deformation of a spring. It is a restoring force, meaning that it always acts to bring the spring back to its original shape.
Spring force acts on two bodies when they are connected by a spring. The spring will exert equal and opposite forces on the two bodies, pulling them towards each other.
The strength of spring force depends on the stiffness of the spring (measured by its spring constant), the distance the spring is stretched or compressed, and the direction of the force relative to the spring's axis.
Spring force is considered a conservative force because the work done by or against it only depends on the initial and final positions of the objects, not the path taken. This means that the total mechanical energy of the system is conserved.
Spring force can be observed in many everyday objects, such as trampolines, door hinges, and shock absorbers. It is also a key component in devices like car suspensions, pogo sticks, and spring scales.
