If you slide a crate across the floor kinetic energy is converted to thermal energy as it comes to rest. Why will adding thermal energy to a stationary crate not cause it to move?

# cos nothing is converting it to kinetic energy # if you add enough thermal energy the box will burn and "move" :)

What is the kinetic energy of a 62.0 g tennis ball being served across court at 150 km per hour ( 94 miles per hour)?
It is 53.8 Joules, approx.
Does conduction require a medium?
Yes. Conduction involves the transfer of thermal energy without any movement of the material medium. For example, when one end of a metal rod is heated, the atoms at that end of the red vibrate more vigorously (gain kinetic energy), and they will collide with the neighbouring less energetic atoms and transfer its kinetic energy them and so on. Without these particles, thermal energy cannot be tranferred through conduction. The only form of thermal energy transfer which does not require a material medium (i.e., the atoms and molecules) is infrared radiation.
What is thermal expansion?
Thermal expansion is the physical change of size of something owing to higher thermal energy of the object. Heat (thermal energy) causes increased atomic motion in materials, and this change in the kinetic energy of the atoms and molecules of a material will cause it to increase in volume. It is a physical characteristic of matter (as opposed to a chemical one), and it is pretty much true across the board. No, ice does not expand when it turns to water, and there are a couple of other exceptions, but, in general, when we heat things, they increase in volume. So the density will decrease but mass remains the same. As in the density formulae, Density= Mass over Volume. When mass do not change and volume increases, it is obvious that it had density to be lower.
What kind of energy does a dryer use?
Electrical energy enters the hair dryer and is converted into kinrtic energy as a smallelectric motor spins a fan blade. Electrical enrgy is also converted into thermal energy in a grid of wires that heat up. The fan forces air across the hot wires , and hot air blows out of the nozzle of the hair dryer. You can hear the sound energy that comes out. In other words in is converted from Electrical energy -to- Kinetic energy and, Electrical energy -to- Thermal energy and, last but not least, Sound energy!

What is an explanation of how water makes electricity?
The hydroelectricity is produced by using the kinetic energy of falling water to drive turbines thus producing mechanical energy which is in turn converted to electrical energy.Dams are built across rivers for this.
Which examples illustrates an object with kinetic energy?

What kind of energy is invloved in hearing and vision?
When a sound is produced, it is carried as vibrations through the air. these vibrations enter the ear and make the ear drum vibrate. This is kinetic energy. The inner ear converts this kinetic energy into electrical energy, which travels along the nerves to the brain. Light enters the eye as electro-magnetic energy. This energy is converted by the retina first into chemical energy, which is then converted to electrical energy in the nerves as the signal travel to the brain. Where nerves join other nerves, the signal has to jump across a gap called a synapse. This is done by converting the energy back into chemical energy, the chemical energy travels across the synapse and is converted back into electrical energy. In short: Ears - Kinetic, electrical and chemical Eyes - Electromagnetic (light), electrical and chemical
