Why do lorries use more energy when they go faster?
Distance traveled per time unit, for example - per hour, goes up linearly with the speed. So double speed means double miles per hour. Some resistances, such as wind resistance for example, increase nonlinear with speed (velocity). Wind resistance increases as something like the third power (speed cubed). So double speed can mean eight times the wind resistance losses. Lubricants, such as oil show similar nonlinear losses. Distance traveled in a unit time increases only linearly with speed. Thus the gain, distance traveled, has gone up less than the efficiency losses.
If the particles of a substance are moving faster do they have more energy?
Yes, generally the faster molecules are moving, the greater their energy. This manifests as higher temperature, and (for gases) higher pressure.
Which would experience more air resistance -a streamlined car travelling slowly or a lorry travelling fast?
A lorry travelling fast would experience more air resistance due to its high speed and larger surface area compared to a streamlined car travelling slowly. The faster an object moves through the air, the greater the resistance it encounters.
What kind of energy does a moving object have?
A moving object has kinetic energy, which is the energy associated with its motion. The faster an object is moving or the more mass it has, the more kinetic energy it possesses.
Is the following sentence true or false the faster the particles of a substance are moving the more energy they have?
True. The kinetic energy of particles is directly proportional to their speed. As the particles move faster, their energy increases.
What are trucks called in England?
Singular: Lorry Plural: Lorries Lorry or Lorries if more than one.
Do faster atoms have more potential energy than slower atoms?
faster atoms have more kinetic energy than slower atoms do.
If time travel was possible could you in the distant future move several light years in a space by traveling close to the speed of light and than traveling backwards through time at regular intervals?
Indeed, time travel, and travelling faster than the speed of light, are intimately related in the Special Theory of Relativity. Looking at the situation from the other side, if it were possible to travel faster than light, then from some point of view, you would be travelling backwards in time. For more details, read about the definition of "simultaneity" in the Special Theory of Relativity.Probably none of the two is possible - travelling backwards in time, and travelling faster than light.Indeed, time travel, and travelling faster than the speed of light, are intimately related in the Special Theory of Relativity.

Why does it take more energy to go faster?
"Kinetic energy" is energy of motion. When you, or any object, move faster, you have more kinetic energy. In order for you or any object to speed up, it needs to have more kinetic energy, and that energy has to come from somewhere. It can come from gasoline burning in the engine to turn the wheels faster, rocket fuel burning in the combustion chamber to accelerate the spacecraft, RF current through the magnets to drag the protons around the ring faster, or glucose burning in the muscles to make the legs go faster. But if more speed is needed, then it'll take more kinetic energy, and that energy must come from somewhere.
What happen when an object travels faster?
It will reach its destination faster. It will also have more kinetic energy.
A rolling ball gains more of this kind of energy when it moves faster?
Kinetic energy
How Can i Get More Faster Energy?
you can drink energy drinks !! (ive never tried them in my life)
What happens to molecules in ice as thermal energy is added?
they start to move-rotating and vibrating and translating more and more and faster and faster.
Does food with more or less sugar burn faster or slower?
more sugar coz it's got more energy so it burns faster
