Kinetic energy equals mass times velocity squared. Since the velocities are the same, they cancel out. Then kinetic energy is dependent on the mass of the 2 objects. Since the truck has more mass, it will have more kinetic energy.

Why solar energy should be introduced on a large scale?

solar energy should be introduced on a large scale because the sun is nature's ultimate energy source


What are the practical benefits of discovering Emc2?

if you mean the equation E = mc 2 (squared), it has no real practical benefits at the present for the average person. It describes a relationship between matter and energy in terms of how much energy can result when converting something completely to energy or how much energy is used up to create matter. It is not something we are able to do at the present time. What it does do is give scientists a better understanding of how are universe works. Although it is not possible to prove that the equation is correct, the equation does seem to work when used by physicists and other scientists when studying the world around us and in developing other formulas and equations. Matter is "stuff". It could be wood, oil, stone, metal, cotton, food, air, gas, dirt, water, anything. Energy could be heat, light, magnetism, gravity, electricity, kinetic energy (something moving or falling), potential energy (something ready to move by itself but being held back as when holding something in your hand and letting it go so it drops becoming kinetic energy). We are able to partially convert matter to energy. One way is to burn something. We burn wood to generate heat and light energy. It is not a complete conversion as we have ashes left over that no longer burn the same way. We burn a candle to create light and some heat energy and some left over gasses that do not burn. When we burn gasoline in an engine (as in an automobile), the heat is converted to kinetic energy (the car moves). We can also explode things to release a large amount of energy at once (and some by products that no longer burn). We generally are not able to convert energy back into matter although it does occur in nature as when plants use sunlight (together with other materials) to grow. We know this because the amount of plant is greater than the amount of material used for the plant and the only other requirement for the plant to grow is light.


Is it easier to get large amounts of energy from fossil fuels than from other energy sources?

no


How does the mass of object affect stopping distance?

With a given braking system (car or rocketship), the system has to dissipate the Kinetic energy of the object. Kinetic formula for K.E. is 1/2MV2 (that 2 means squared). Therefore, the stopping distance increases linearly with the MASS. Another way to look at it is the Force required to stop the MASS, which is: F=M x A, so again as MASS increases the required Force increases Linearly.

If a large truck and a small car are moving at the same speed which has the greater kinetic energy?

The truck - greater mass.


What form of energy that is found in large moving objects?

Kinetic energy is the form of energy found in large moving objects. It is energy associated with motion.


A slow moving steamroller has a large amount of kinetic energy too?

Although a slow-moving object may not have a high speed, it can still possess a significant amount of kinetic energy if it has a large mass. This is because kinetic energy depends not only on speed but also on the object's mass. In the case of a steamroller, its large mass contributes to its substantial kinetic energy even when moving slowly.


Which has more kinetic energy- A small object or a large object moving at the speed of 25 mph?

The large object moving at 25 mph would have more kinetic energy compared to the small object, assuming they have the same mass. Kinetic energy is dependent on both mass and velocity, so in this case, the larger object would have more kinetic energy due to its greater mass.


Does a small horse has the same amount of kinetic energy as a larger horse moving at the same speed?

The more massive horse that is moving at the same speed will have greater kinetic energy. How do you define large and small? A small fat horse may have more mass than a large skinny horse.


Is Kientic energy greater than potential energy?

It depends on the specifics of the situation. Kinetic energy is the energy an object possesses due to its motion, while potential energy is the energy that an object possesses due to its position or state. In general, kinetic energy can be greater than potential energy, for example when an object is moving quickly or has a large mass.


How does the kinetic energy change if the objects mass is twice as large?

If an object's mass is twice as large, its kinetic energy will also be twice as large, assuming the velocity remains constant. Kinetic energy is directly proportional to an object's mass, so an increase in mass will result in a proportional increase in kinetic energy.


Would an object with a larger mass have more kinetic energy than an object with a smaller mass?

Yes, an object with a larger mass would have more kinetic energy than an object with a smaller mass if they are moving at the same speed. Kinetic energy is directly proportional to mass and speed, so a larger mass would contribute to a greater amount of kinetic energy, assuming the speed is constant.


Where is the most kinetic energy?

The most kinetic energy is typically found in moving objects that have a high velocity and a large mass. For example, a speeding car on a highway or a fast-moving bullet fired from a gun would have a significant amount of kinetic energy due to their velocity and mass.


Which quantity has the greatest influence on the amount of kinetic energy that a large truck has while moving down the highway?

Kinetic energy is equal to mv2/2, where m is mass and v is speed. Since speed is squared in this formula, changes in speed have a greater influence on the kinetic energy than do changes in mass.


Should a large truck and a small car moving at the same speed have the same kinetic energy?

No. The large truck has more kinetic energy than the car. Mass is a variable in the equation for determining kinetic energy. Kinetic energy equals 1/2 the mass of the object time the speed (really velocity) squared.


What has more kinetic energy a large dog sitting on a sidewalk or a small cat running down the street?

A small cat running down the street has more kinetic energy than a large dog sitting on a sidewalk. Kinetic energy is directly proportional to an object's mass and speed, and since the cat is in motion, its kinetic energy is greater even though it is smaller in size compared to the dog.
