How would the kinetic energy of a 12000-kg train compare with the kinetic energy of a 900-kg compact car if both were traveling at the same speed?
The kinetic energy of the 12000-kg train would be much greater than that of the 900-kg compact car, as kinetic energy is directly proportional to the mass of the object. Therefore, the train would have significantly more kinetic energy than the compact car when traveling at the same speed.
What else can I help you with?
A dump truck a sports car and a bicycle are traveling at the same velocity's compare their kinetic energies?
The kinetic energy of an object is given by the formula KE = 0.5 * m * v^2, where m is the mass and v is the velocity of the object. Since all three are traveling at the same velocity, the object with the largest mass (the dump truck) will have the highest kinetic energy, followed by the sports car, and then the bicycle.
What energy is in a traveling bullet?
A traveling bullet primarily carries kinetic energy due to its motion through the air. This kinetic energy is derived from the initial potential energy stored in the bullet when it was fired.
If two bicycles have the same mass but one is traveling at 10 ms and the other is traveling at 15 ms which has more kinetic energy?
The bicycle traveling at 15 m/s has more kinetic energy because kinetic energy is proportional to the square of the velocity. Since the mass is the same for both bicycles, the one traveling faster will have a greater kinetic energy.
Which car has the most kinetic energy?
A car traveling at a higher speed will have more kinetic energy than a car moving at a slower speed. So, the car with the most kinetic energy would be the one traveling at the highest speed.
A truck and a car are traveling down the highway at the same speed If the truck has a greater mass than the car how do their kinetic energies compare?
The kinetic energy of an object is directly proportional to its mass and speed. Since the truck has a greater mass than the car but they are traveling at the same speed, the truck will have more kinetic energy than the car.

The kinetic energy of an object is directly proportional to its mass and speed. Since the truck has a greater mass than the car but they are traveling at the same speed, the truck will have more kinetic energy than the car.
How to compare kinetic energy on a car?
The formula for kinetic energy is: KE =( mv2)/2 m= mass (not weight) v= velocity A more massive car will have more kinetic energy than a lighter one traveling at the same speed. A faster moving car will have much more kinetic energy than an identical car moving slower.
How does the kinetic of solids liquids and gases compare?
The kinetic energy is lowest in solids, higher in liquids, and highest in gases.
Calculate the kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph?
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
Does kinetic energy decrease when traveling up hill?
Yes, kinetic energy decreases when traveling uphill because some of the energy is converted into potential energy to overcome gravity. This results in a decrease in the speed of the object.
Why does a train have more kinetic energy than a car traveling at the same speed?
A train has more kinetic energy than a car traveling at the same speed because the train has significantly more mass. Kinetic energy is directly proportional to an object's mass - the more mass an object has, the more kinetic energy it will possess at a given speed.
What type of energy a car is traveling 45 mph have?
A car traveling at 45 mph has kinetic energy, which is the energy of motion. As the car moves, its speed and mass contribute to its kinetic energy. This energy is what enables the car to perform work and overcome resistance while in motion.
Which has a greater kinetic energy a car traveling at 30 km h or a car half that mass traveling at 60 km h?
60. K= 1/2mv^2 therefore when v is larger, there is more kinetic energy
