Potential vs kinetic energy

As the swing reaches its highest point it has all potential energy. When it reaches the lowest, it is all kinetic energy. As it moves up, the pull of gravity changes the kinetic into potential.

Fleur is full of potential energy. She breaks into converting it into kinetic energy at a whim. Usually it is predictable:

  • To get the cat
  • To go play on the playset
  • To pet a dog
  • To be chased
  • To get into the street

Tonight she caught me by surprise. After bath, she wanted to read the Pout-Pout Fish. And right before the kissy part she leaves the room and tells me to get up. I try to finish, but she is insistent. So, I do and she takes off. It was her favorite route in a circle.

Coefficient of friction

One of the considerations for letting Fleur go slide is the pants she wears. Something I didn’t know before being a parent was different pants have different coefficients of friction.

The force required to move two sliding surfaces over each other, divided by the force holding them together. It is reduced once the motion has started.

And drag.

Every time I let her go with the slicker pants, I chide myself for not having made the better physics choice. She flies down the slide.

It is one of those designs with a bump in the middle. She can go so fast she gets enough air to land just before careening off the end.

With pants providing enough friction, she doesn’t get too much speed. And I don’t feel the need to be too vigilant.

Ride FOMO

This past weekend on Saturday, we went to the mall where there is a place with bounce houses and a new marry go round with three horses. It has a warning that a parent needs to be present and not allow the child to be off the horses. Easier said than done when your child has ride fear of missing out.

Fleur wanted on any random one at first. I put her on the red one and started the ride. As she started to get off it, I stopped the ride. She got on the yellow one, the one in her eye sight. I started the ride and within a minute I had to stop it again as she transferred to the blue. Then she wanted on the red one then yellow then blue then red.

On Sunday, we went to the park she loves. This time the FOMO reared its head in getting upset about other children trying to use the same slide. And wanting to use the next swing over, even the one identical to the one she was in.

That said, once she found the right slides (one rated for 5-12 year olds), she wanted to do them over and over and over. The issue with the other children is they were preventing her from getting back on it fast enough.
