A force between two moving objects that make it hard for them to move?
Frictional force exist between two moving objects that make it hard for them to move.Frictional force causes objects to slow down if force is not applied continuously to the moving objects. Frictional force causes some of the energy to be converted into the wasteful form of energy.
What are some objects that contain mechanical energy?
"the energy in moving things is mechanical energy. wind, moving water, and falling rocks all have mechanical energy. when you walk, run, or ride a bicyle, you are using mechanical energy. sound is a form of mechanical energy."-Concepts and Challenges in Physical Science
Why are some photographs of moving objects clear enough?
A fast shutter speed enables a photographer to capture clear images of moving objects.
How are objects in the universe moving?
While there is some seemingly random movement, in general the objects are moving away from one another. In other words, the Universe is expanding.
Why do some objects move continuously while some moving objects stop suddenly?
Because of friction, Friction is what causes moving objects to slow down and eventually stop. This is an important science idea we can use to describe the force that pushes back on a moving object and makes it slow down and stop.
What kind of energy does a non moving bicycle have?
Potential energy, and then the chemical energy in its material.A stopped bicycle doesn't have much energy. It does (almost always) have some flammable parts which contain potential chemical energy. Even when stopped, if it is standing up it has some gravitation potential energy that would be released if it fell over. The inflated tires have some amount of elastic energy. Compressed air in the tires has some energy content. None of this amounts to very much, in comparison to the energy of a moving bicycle.
How does friction affect the energy in a closed system of moving parts?
Friction affects the efficiency of a system since two objects rub against each other. When this happens, there is created which reduces the energy in the system.
Does matter have heat energy when it is cold?
Because molecules in matter are always moving, virtually all matter has some heat energy, even when it seems cold to you. Matter that seems cold is merely not as hot as objects near it, or as hot as your hand. It still has temperature and thus heat energy. As long as its temperature is above -459.7°, it has heat energy.
Can thermal energy flow from cooler objects to warmer objects?
energy alwayy flow from high density to low density
Does objects at rest actually move?
Well, technically yes. Everything in the universe is moving at some rate. Not to mention that the earth is moving, thus everything on Earth is moving with it. !
Does all objects in the universe radiate some form of energy?
yes
