Where does the kinetic energy come from when a car accelerates uniformly starting from rest?

Chemical energy in the gasoline is released by burning a mixture of 'atomized'
gasoline and air. Most of the energy is used to heat the surrounding air, by means
of the engine's cooling system. The remaining small part of the energy is used
to turn the engine parts, which transfer the kinetic energy to the vehicle by way
of the transmission and the wheels.
When the vehicle needs to slow down or stop, the kinetic energy is instantly and
efficiently used to heat more of the surrounding air, by means of the braking system.

The kinetic or potential energy associated with the motion and position of an object is?
This is actually two questions. Energy relating to the motion of an object is kinetic energy. Energy related to its position is potential energy (as with a brick suspended at some distance above the ground). Release the brick and its potential energy is converted to kinetic energy. The two are complementary. As the brick accelerates toward the ground its kinetic energy increases; as the distance decreases during that acceleration, it's potential energy decreases.
Sprinters set in the starting blocks at the beginning of a race rely on what kind of energy conversion?

If the potential energy of a swing is 200 J at its highest point and 50 J at its lowest point what is the kinetic energy of the swing at its lowest point if mechanical energy is conserved?
150J, as the potential energy has been converted to kinetic energy as the swing accelerates downwards (and forwards) from the top of its swing. Therefore the decrease in potential energy corresponds directly to the increase in kinetic energy if we are ignoring things like friction. So KE = 200-50= 150
What kind of energy is energy motion?
It is kinetic energy.
Energy an object has due to its motion?
kinetic energyThe energy of motion is kinetic energy.
Does kinetic energy decreases as a box accelerates down an inclined plane?
Kinetic energy increases; potential energy decreases, because the object is now in motion
What is the initial transfer of energy that accelerates the rock down the side of the mountain?
Potential energy is converted into kinetic energy
Dropping an iron ball is kinetic energy?
Anything in motion has kinetic energy. KE=1/2 m v^2 The ball starts with potential energy due to its height above the ground. The energy is converted to kinetic energy as the object accelerates.
Is kinetic energy of a body in motion equals the product of half its acceleration?
No. Kinetic energy is 1/2 times mass times velocity squared - so as you can see, acceleration doesn't even enter the equation. If it accelerates, the speed will change, though, and so will its kinetic energy.

What causes the current to decrease as an induction motor accelerates?
Because power is needed to accelerate the rotor and thus increase its kinetic energy.
