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

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.

mass and to the square of speed. If we may assume that both cars are on the same
planet, then we know that the 3,000-lb truck has more mass than the 2,000-lb car.
Since their speeds are equal, their respective kinetic energies are proportional to their
masses, and the truck has 50% more KE than the car has.

What moves faster large molecules or small molecules?
given the same amount of kinetic energy a smaller molecule would have a high velocity according to k=mv^2
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.
A slow moving steamroller has a large amount of kinetic energy too?
Yes.
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.
How does the kinetic energy change if the objects mass is twice as large?
Assuming the larger mass is moving at the same speed as the original mass, the kinetic energy will double.
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.
Which has more kinetic energy- A small object or a large object moving at the speed of 25 mph?
You don't say what speed the small object has. If both have the same speed then the heavier one will have more kinetic energy.
Which of these has the most kinetic energy-?
These include very large things, like planets, and very small ones, like atoms. The heavier a thing is, and the faster it moves, the more kinetic energy it has.
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.
When does a coaster have a large amount of Kinetic Energy and when does it have a large amount of Potential Energy?
The coaster have a large amount of potential energy when it gain height, kinetic energy when it gain speed instead.
Would an object with a larger mass have more kinetic energy than an object with a smaller mass?
Maybe and maybe not. It depends on the speed of the two objects. A small object moving very fast might have more kinetic energy than a large object moving slowly.
Why does an arrow shot from a bow have a large momentum?
When an arrow is shot from a bow it gains kinetic energy from elasticity in the bw string. When pulled back there is potential energy. The farther it it pulled back the more energy is gained. When released it is converted into kinetic energy. Thus it has large Momentum Momentum is the force and speed at which the object is moving
What is the sum of the kinetic and potential energy of large scale objects in a system?
The sum of the potential and kinetic energy of large-scale objects in a system is the Hamiltonian.
