Why does a large truck have greater kinetic energy than a small car going the same speed?
/2mv^2 where m is mass and v is velocity. The fuel used is proportional (in a simplified view) to the kinetic energy of the car. Therefore if cars are to driven at the same speed (and ignoring the individual efficiencies of different models) the car that has a larger mass uses more fuel to get to and maintain the same speed
What else can I help you with?
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 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.
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.
A cart pushing ten bricks or a cart pushing twenty bricks using the same force and going the same distance which has greater kinetic energy?
The same force could not be applied to travel the same distance if there is a larger mass in one instance. Applied force will accelerate a given mass twice as much as a mass half as large. If both are moving the same distance, the 20-brick cart had more kinetic energy when in motion.
What is the sum of the kinetic and potential energy of large scale objects in a system?
The sum of kinetic and potential energy of large scale objects in a system is called the total mechanical energy. It remains constant in the absence of external forces like friction or air resistance, according to the law of conservation of energy. Mathematically, it can be represented as the sum of kinetic energy and potential energy: Total Mechanical Energy = Kinetic Energy + Potential Energy.

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.
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.
What are two factors that give a large meteorite more kinetic energy than a batted baseball?
Kinetic energy is determined by the formula, Ek = mv2/2, and a large meteor has more mass and velocity than a baseball. Mass matters, but the velocity gets squared. is More Information: Two factors that give any meteorite higher kinetic energy than a batted baseball, are their comparative masses and velocities. A baseball may weigh about 9 oz and travels a little over a hundred miles an hour off the bat. Even a meteorite of small mass has more kinetic energy than that because of its high velocity (maybe about 25,000 miles an hour, or more). A large meteorite would have high velocity also, but given large mass, it would have extremely high kinetic energy.
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.
What possesses most kinetic energy?
Kinetic energy is calculated as (1/2) x mass x speed squared, so to have a lot of kinetic energy, an object must have a large mass, a large speed, or both. Stars have tremendous amounts of kinetic energy, galaxies even more.Kinetic energy is calculated as (1/2) x mass x speed squared, so to have a lot of kinetic energy, an object must have a large mass, a large speed, or both.

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.

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.
