If you think of a car, fuel is burnt to make the car move. Chemical energy into kinetic energy. The reason the car stops when the fuel runs out is because the car is having to work against forces acting against it like friction with the road, air resistance and gravity acting on it's own mass.
The cars motion or kinetic energy is converted into kinetic energy in the particles in the air and heat due to friction.
Total energy can still be conserved even if the energy of motion is not conserved if other forms of energy are changing in response. For example, potential energy may increase to compensate for a decrease in kinetic energy. As long as the total energy in a closed system remains constant, conservation of energy is upheld.

What is conserved during collisions?
Momentum and energy are conserved during collisions. Momentum is the product of an object's mass and velocity, while energy is the capacity to do work. In an isolated system, the total momentum and total energy before and after a collision will remain constant.
Energy is conserved when an object gains speed while falling?
Yes, energy is conserved in a falling object when it gains speed. The potential energy of the object due to its position is converted into kinetic energy as it accelerates, keeping the total energy constant.
What is mhecanical energy?
Mechanical energy is the sum of potential energy and kinetic energy in a system. Potential energy is the energy stored in an object due to its position, while kinetic energy is the energy an object possesses due to its motion. Total mechanical energy is conserved in a closed system, meaning it remains constant unless acted upon by an external force.
What is the the total energy of motion and position of an object?
The total energy of an object is the sum of its kinetic energy (energy of motion) and potential energy (energy of position). Kinetic energy is associated with the object's motion, while potential energy is associated with its position in a gravitational or electric field.
Why both kinetic and potential energy are often treated as kinds of mechanical energy?
Kinetic energy is associated with an object's motion, while potential energy is associated with its position or state. In the context of mechanical energy, the total energy of a system can be seen as the sum of kinetic and potential energy. This distinction allows for a comprehensive understanding of how energy is transformed and conserved in mechanical systems.

Is energy conserved only in exothermic reactions?
No, energy is conserved in all chemical reactions, not just exothermic ones. In an exothermic reaction, energy is released as heat to the surroundings, while in an endothermic reaction, energy is absorbed from the surroundings. The total energy of the system and surroundings remains constant during both types of reactions.
What are the characteristics of mechanical energy?
Mechanical energy is the sum of kinetic and potential energy in a system. It is associated with motion and position of an object. Mechanical energy is conserved in the absence of non-conservative forces like friction.
What is total minus energy kinetic energy is equal to?
Total minus kinetic energy is equal to potential energy. Potential energy is the energy stored in an object due to its position or state, while kinetic energy is the energy of motion.
How is enery related to motion?
While a object is in motion it poesses Kinetic Energy(the energy or motion).
Comparison between elastic and inelastic collision?
In an elastic collision, kinetic energy is conserved and momentum is conserved. Both objects bounce off each other after the collision. In an inelastic collision, kinetic energy is not conserved, but momentum is conserved. The objects stick together or deform after the collision.
Energy related to motion or position of matter is?
Kinetic energy relates to the motion of matter, while potential energy refers to the position of matter in a given system. Together, these two forms of energy make up the total mechanical energy of a system.
What is the total kinetic energy and potential energy?
It is the sum of potential and kinetic energy.
