In a standard car, the energy becomes heat in the brakes. Keep that up for
too long, and they'll burn up. I have personally had the pleasure of coming
down a mountain in China where that technique was applied, and seeing both
front tires ignite simultaneously.
In an electric or hybrid car, some of the energy goes back in to recharge the batteries.
What else can I help you with?
How are Charles and boyles law different?
Boyle's law applies to pressures and volumes at constant temperature P1V1 = P2V2. Charles' Law applies to volume and temperature at constant pressure V1/T1 = V2/T2. With temperatures in Kelvin the relationship between temperature and volume is directly proportional.
How does law of constant proportion applies in sea water?
The law of constant proportion, also known as the law of definite proportions, states that a chemical compound always contains its component elements in fixed ratio by mass. In seawater, this law applies to the dissolved salts, primarily sodium chloride, which consistently makes up about 3.5% of seawater by mass. Regardless of where seawater is sampled, the proportion of these dissolved salts remains relatively constant, demonstrating that the chemical composition of seawater is uniform despite variations in other components. This consistency is crucial for marine life and oceanic processes.
How does the law of conservation apply to skatboarder on a half pipe?
The law of conservation of energy applies to a skateboarder on a half pipe by ensuring that the total mechanical energy in the system (potential energy due to height and kinetic energy due to motion) remains constant, neglecting any external forces like friction or air resistance. As the skateboarder moves up and down the half pipe, their potential energy is converted into kinetic energy and vice versa, but the total energy remains the same.
If the law of conservation of energy applies to a situation then?
the total amount of energy in a closed system remains constant over time. Energy cannot be created or destroyed, only transferred or transformed from one form to another.
Is the location of the stored energy in the atom?
Energy is not a substance, so you can't always pinpoint an exact "location" for it. Specifically in the case of potential energy, which is what I believe what you mean when you say "stored energy", the energy is not "stored in an object"; rather, it is defined by the RELATIONSHIP between two or more objects. For instance, if two magnets attract one another, pulling them apart requires force; therefore, when they are separate they have more energy (potential energy) than when they are together. The same applies to any type of potential energy, such as chemical energy, nuclear energy, gravitational potential energy, electrical potential energy.
What is constant in ohms law?
Ohm's original law was 'The potential difference across a conductor is proportional to the current flowing through it, provided physical conditions such as temperature remain constant.'Today Ohm's law is expressed as E = IR or sometimes V = IR,the units being Volts, Amps and Ohms.AnswerOhm's Law ('the current flowing along a conductor, at constant temperature, is directly proportional to the potential difference across that conductor') only applies when the resistance of the conductor is constant so, when verifying Ohm's Law, the temperature must be kept constant, in order to keep the resistance constant.It should be pointed out that the ratio of voltage (U) to current (R) is called resistance (R), and the resistance of a circuit can be found from the equation, R = U/I whether Ohm's Law applies or not -but Ohm's Law itself only applies when the ratio is constant over a range of voltage variation.
Describe the energy transformations that occur when you toss a ball upward and it falls?
When you toss a ball upward, your body applies kinetic energy to the ball, giving it potential energy as it rises. As the ball falls back down, its potential energy is converted back into kinetic energy, leading to a decrease in potential energy and an increase in kinetic energy until it reaches the ground.
An objects resistance to change in motion?
Inertia. Inertia applies to both increases and decreases in velocity.
What is the significance of the constant temperature reference in ohms law?
As temperature affects resistivity, the resistance of a conductor may change if its temperature is allowed to increase. For pure metal conductors, the resistance generally increases as the temperature increases.Ohm's Law ('the current flowing along a conductor, at constant temperature, is directly proportional to the potential difference across that conductor') only applies when the resistance of the conductor is constant so, when verifying Ohm's Law, the temperature must be kept constant, in order to keep the resistance constant.It should be pointed out that the ratio of voltage (U) to current (R) is called resistance (R), and the resistance of a circuit can be found from the equation, R = U/I whether Ohm's Law applies or not -but Ohm's Law itself only applies when the ratio is constant over a range of voltage variation.
What does law of constant composition applies to?
The law of constant composition applies to chemical compounds, stating that a compound is always made up of the same elements in the same proportion by mass. This means that the ratio of elements in a compound is fixed and does not change regardless of the source or method of preparation.
How are the laws of conservation of mass and conservation of energy similar and how are they different?
The laws of conservation of mass and conservation of energy are similar in that both state that the total amount of mass or energy in a closed system remains constant over time. However, the conservation of mass applies specifically to mass, while the conservation of energy applies to energy in its various forms (kinetic, potential, etc.).
How do you calculate the speed of something going down a hill?
Average speed = Distance travelled/Time taken. And that applies whether the object is going downhill, uphill or is on a roller coaster.
How are Charles and boyles law different?
Boyle's law applies to pressures and volumes at constant temperature P1V1 = P2V2. Charles' Law applies to volume and temperature at constant pressure V1/T1 = V2/T2. With temperatures in Kelvin the relationship between temperature and volume is directly proportional.
How do you explain current in Ohm's Law?
I=V/R, current = voltage divided by resistanceAnswerOhm's Law states that 'the current flowing through a conductor, at constant temperature, is directly proportional to the potential difference across the conductor'.Ohm's Law only applies when the ratio of voltage to current is constant over a wide range of voltages. If the ratio changes, then Ohm's Law does not apply.
Why does Ohm's Law hold true only at a constant temperature?
Ohm's Law holds true only at a constant temperature because it assumes a linear relationship between voltage, current, and resistance, which is only valid when temperature remains constant. Changes in temperature can alter the resistance of a material, leading to deviations from Ohm's Law.
What are the four basic units of electricity?
Ohm's Law describes the relationship between current ( symbol: I ) and potential difference( symbol: E, V, or U ) under very specific circumstances. It states that 'the current passing through a conductor is proportional to the potential difference across the ends of that conductor, providing various physical conditions, such as temperature, remain constant'.Another way of expressing Ohm's Law is to say that it applies to a conductor (or device) whenever 'the ratio of potential difference to current is constant for variations in potential difference'. The ratio of potential difference to current is known as resistance ( symbol: R ).It should be noted that Ohm's Law is NOT a universal law, and only applies as described in the second paragraph, above. In fact, it applies in very few cases. Hardly any conductors obey Ohm's Law unless their temperatures are held constant (which doesn't normally happen in practice!) and devices such as diodes, etc., do not obey Ohm's Law.So there are three, not four, quantities involved with Ohm's Law: potential difference (which is also known as voltage) expressed in volts (symbol: V), current expressed in amperes (symbol: A), and resistance expressed in ohms (symbol: the Greek upper-case character 'omega').
How and can you increase the potential energy an object has?
You can increase an object's potential energy by either increasing its height or applying a force in the direction opposite to the field it is in. This applies to gravitational potential energy (increasing height) and elastic potential energy (stretching a spring).
