When you wind up a spring in a toy?

When we wind up the spring of a toy-car by using a winding key, then some work is done by us due to which the spring gets coiled more tightly. The work done in winding the spring gets stored up in the tightly coiled-up spring (or wound-up spring) in the form of elastic potential energy.

What happens when u stretch a rubber band?

A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape. That is why a rubber band changes its shape even though it is a solid. Also, if excessive force is applied then the rubber band would break.

What type of energy is stretching a rubber band?

elastic potential energy
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy.

What happens when you wind up a toy?

Examine how wind-up toys work. Inside each toy is a torsion spring that stores energy by being wound, then releases that energy as it unwinds which the mechanisms inside the toy turn into movement.

How does winding a toy cause movement of the toy?

When the wider which we use to wind-up the spring is released, the spring in the toy unwinds and the spring potential energy in the spring gets converted into kinetic energy. This converted kinetic energy gives a velocity to the gears attached to the spring and the toy starts to move.

What is the spring constant of a rubber band?

After you get the rubber band stretched just a little bit, it is very spring-like. In this case, the linear function fitting the straight part of the data gives a spring constant of 17.38 N/m.

Why does rubber band heat up when stretched?

When molecules, not just rubber molecules, but any molecules, form crystals, they give off heat. This is why the rubber band feels hot when its stretched. When you let go of the rubber band, the polymer molecules break out of those crystals. Whenever molecules break out of crystals, they absorb heat.

What energy is present in a stretched spring?

Figure 1. Elastic potential energy stored by a spring. Elastic potential energy is the potential energy stored by the deformation of an elastic material, such as a spring seen in Figure 1.

What type of energy contains a compressed spring and stretched rubber bands?

Mechanical energy is energy stored in objects by tension. Compressed springs and stretched rubber bands are examples of stored mechanical energy.

How does a wind up spring work?

When you rotate the winder with force, the energy is stored in the wound up spring as potential energy. As you release the winder, the spring unfolds and this converts the stored energy into kinetic energy, driving the gear and in turn generating movement of the attached parts down the line.

How do you wind a toy?

You can wind up a mechanical toy (also called a wind up toy), or wind up just before you pitch a baseball. This involves a step back in the direction of second base before a forward step with the hands lifted overhead, preparing to throw the ball.
