No, the kinetic energy of a moving vehicle actually increases with its speed. Kinetic energy is proportional to the square of the velocity, so the faster the vehicle moves, the more kinetic energy it has.
"Mechanical energy" is basically the sum of potential energy, and kinetic energy - thus, an object has more mechanical energy than another one when this sum is greater. You may just need to calculate these energies and add them up, to find out in specific cases.
Mechanical energy is the sum of potential and kinetic energy in a system. Kinetic energy is the energy of movement, while potential energy is related to an object's position or condition. So, while mechanical energy includes the energy associated with movement, it also encompasses other forms of energy within a system.
The kinetic energy of a vehicle is directly proportional to its mass and velocity. A larger vehicle will have more kinetic energy than a smaller vehicle traveling at the same velocity. This means that a larger vehicle will require more distance to come to a stop compared to a smaller vehicle, all else being equal.
The kinetic energy of a vehicle is directly related to its speed. A vehicle with higher kinetic energy (higher speed) will require a longer stopping distance as more energy needs to be dissipated to bring the vehicle to a stop. This is why speeding increases the likelihood of accidents as it reduces the time available to stop.

Mechanical energy is the sum of kinetic energy and potential energy of some object. So any object in motion, has potential to be in motion, or has both has mechanical energy. Your car in motion has kinetic energy and potential for more kinetic energy in the gasoline that it runs on. So your car has mechanical energy. Or you up on the three-meter diving board at the pool have potential for kinetic energy when you take a swan dive off that board. You have mechanical energy there. But, bottom line, pretty much any object that is either in motion or can be put into motion has a form of mechanical energy.

Kinetic energy is directly involved in moving matter. It is the energy that an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.
When driving uphill, gravity acts against your kinetic energy, requiring more energy to maintain speed. When driving downhill, gravity aids your kinetic energy, allowing you to maintain or increase speed more easily. In both cases, potential energy is converted to kinetic energy as the vehicle moves.
The term 'mechanical energy' is a compound noun, a noun made up of two or more words that form a noun with a meaning of its own.
It would be something like:(Kinetic energy) + (Potential energy) = (constant).However, note that mechanical energy is not conserved: consider an inelastic collision, for example.Refer to the first law of thermodynamics for more information (related links below).
Kinetic energy is the energy of motion, KE=mv2/2.Thermal energy is different from kinetic energy.Thermal energy is associated with the temperature of a body, the heat gained by increasing the temperature. That heat gives molecules more kinetic energy and more potential energy and may also give molecules more more electronic energy.
A roller coaster has more potential energy at the bottom. There are 2 types of energy, potential and kinetic. energy closer to a surface or floor is potential energy and objects in the middle of it all has kinetic energy.
