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.
What else can I help you with?
If an object is accelerating how does its kinetic energy change?
The kinetic energy of an object increases as it accelerates. This is because kinetic energy is directly proportional to the square of the object's velocity. As the object accelerates, its velocity increases, resulting in a greater kinetic energy.
An avalanche demonstrates what kind of energy conversion?
Gravitational potential energy to kinetic energy
As an object falls the gravitational potential energy of the object is converted to what?
As an object falls, its gravitational potential energy is converted into kinetic energy. This occurs as the object accelerates due to gravity, increasing its speed and kinetic energy.
What energy transformation occurs when a jet plane rapidly accelerates on the runway?
When a jet plane accelerates on the runway, the engines convert chemical energy from fuel into kinetic energy of motion. This kinetic energy increases as the plane gains speed, allowing it to overcome inertia and take off into the air.
When an object that is falling loose potential energy what is this transformed into?
The potential energy is transformed into kinetic energy, heat and sometimes sound.

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?

Is a pushed down spring kinetic energy?
No the energy stored in a compressed spring is not kinetic energy.
What energy is used when skydiving?
Potential energy is converted to kinetic energy when skydiving. As the skydiver jumps from the plane, they have a high potential energy due to their height above the ground. This potential energy is then converted into kinetic energy as the skydiver accelerates towards the ground.
Which example best illustrates a change from elastic potential energy to kinetic energy?
A ball dropped from a height transforms its stored elastic potential energy due to gravity into kinetic energy as it accelerates downward.
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.
What happens with the potential energy when objects drops?
When an object drops, its potential energy is converted into kinetic energy as it accelerates towards the ground. As the object falls, its potential energy decreases while its kinetic energy increases until it reaches the ground, where it has no more potential energy but maximum kinetic energy.
