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.

To compare kinetic energy of cars, you can calculate it using the formula KE = 1/2 * m * v^2, where m is the mass of the car and v is its velocity. The car with higher kinetic energy will have either greater mass, higher velocity, or both. Remember that kinetic energy is directly proportional to both mass and the square of velocity.

What parts of a car use kinetic energy?
The wheels and engine components of a car use kinetic energy. When the car is in motion, kinetic energy is generated and transferred to these components to enable movement.
Identify the item that has kinetic energy?
A moving car has kinetic energy.
A car's motor does 2500 kJ of work in moving the car however the car only has 18 kJ of kinetic energy. Explain how this can happen?
The car's motor does work to transfer energy, a portion of which is used for purposes other than kinetic energy, such as overcoming friction, air resistance, or internal mechanical losses. Therefore, not all the energy output by the motor contributes to the car's kinetic energy, resulting in a discrepancy between the work done by the motor and the car's kinetic energy.
What correctly describes the difference in kinetic energy between the two cars?
The kinetic energy of a moving object is determined by its mass and speed. If two cars have different masses but the same speed, the car with the greater mass will have more kinetic energy. If they have the same mass but different speeds, the car moving faster will have more kinetic energy.
What is a energy transformation in a car engine?
The chemical energy is transformed in kinetic energy.
Is a real car a kinetic energy?
A real car possesses kinetic energy when it is in motion due to the movement of its mass. This kinetic energy is a form of energy associated with an object's motion and is dependent on its speed and mass.
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.
Why that the car is an ex of kinetic energy?
Kinetic energy is "moving energy". A car moves, it has kinetic energy. In the case of a car crash the energy is released-->smash/bang!!!
Is a car a kinetic or potential energy?
Energy due to motion is kinetic energy, so the energy of the car due to it's motion is kinetic.
What kind of energy does a moving car have?
A moving car has kinetic energy, which is the energy of motion possessed by an object. The amount of kinetic energy that a car has is influenced by its mass and velocity.
What will a car's kinetic energy be if the car's speed triples?
If a car's speed triples, its kinetic energy will increase by a factor of nine since kinetic energy is proportional to the square of velocity.
What energy has a moving car got?
A moving car has kinetic energy, which is the energy of motion. This energy is determined by the car's mass and speed.
What is an example of kinetice energy?
An example of kinetic energy is a moving car. As the car is in motion, it possesses kinetic energy due to its velocity. The faster the car is moving, the more kinetic energy it has.
In the following situations which one does not have kinetic energy?
A stationary car parked on the side of the road does not have kinetic energy, as kinetic energy is the energy of motion and the car is not moving.
Which is example of kinetic energy?
Any moving object has kinetic energy.
What is kinetic energy and what is an example of a kinetic energy?
Kinetic energy is the energy possessed by an object in motion. An example of kinetic energy is a moving car.
Which of the best demonstrates kinetic energy?
A moving car is a good example of kinetic energy. The car's motion is powered by its kinetic energy, which is generated from its speed and mass.
