Which device converts electric energy into rotational kinetic energy?
Some options:electric motorsolenoideinstein electromagnetic pump with no moving partsetc.
Distinguish between heat and internal energy?
Heat is defined as "energy in transit owed to a difference in temperature". The "internal energy" (or intrinsic energy) is the sum of the energy of all the atoms or molecules in a given body. In gases it includes the molecules or atoms kinetic energy (translation energy), rotational energy, vibrational energy, electronic energy... Solids lack the kinetic and rotational energies. Internal energy is thermal energy. So is heat, but heat is thermal energy in motion due to a difference in temperature.
How do you calculate the gain of Kinetic Energy?
You calculate the new kinetic energy, you calculate the old kinetic energy, then you subtract.
What is kinetic energy versus square velocity?
Kinetic energy is directly proportional to the square of an object's velocity. If you graph the object's kinetic energy against the square of its speed, the graph is a straight line, and the slope of the line is 1/2 of the object's mass.
What type of energy is kinetic and potential?
Kinetic and potential energy are types of mechanical energy.
Is it possible to change translational kinetic energy of an object without changing it rotational energy?
yes
What is a form of kinetic energy that occurs within a molecule when the bonds are stretched or bent a translational b rotational c vibrational d internal?
Vibrational.
Why does a Screw takes less forces to move into wood than a nail?
a screw possesses both rotational kinetic energy and translational kinetic energy while a nail possesses only translational kinetic energy as it moves through the piece of wood hence the screw moves faster since its motion is backed by more energy than the nail.
What is translational energy?
The kinetic energy of an object is the energy which it possesses due to its motion.Translation kinetic energy is energy due to motion along a path (as opposed to rotational kinetic energy, which energy do the motion created when an object rotates, or changes its orientation in space.)
What will be greater in a disk rotational kinetic energy or translational kinetic energy?
Either of those quantities can change without any change to the other. They're independent of each other, so there's no general reason why either one should be greater. You can throw a frisbee without spinning it at all. And you can balance it on the point of a pencil and spin it without giving it any translational KE at all.
How does a bowling ball being rolled down a bowling alley have kinetic energy?
Kinetic energy is the energy a moving body - in this case, the bowling ball - has. The ball actually has two forms of kinetic energy: rotational and translational. The rotational energy is the energy of it's spin, and the translational energy is the energy of it's motion towards the pins.
A basketball rolling across a flat floor has energy?
A basketball rolling across a flat floor has translational and rotational kinetic energy. There's a force of gravity pulling the ball down towards the floor, and a reaction force pushing the ball up away from the floor.
What two types of energy can make up the mechanical energy of an object?
A generator transforms mechanical energy into electricity, by spinning a magnet in a coil.The regenerative braking system in hybrid cars similarly transforms the braking mechanical energy into electricity.Please see the related links for details.
What portion of the total kinetic energy of a rolling object is translational energy?
If an object is rolling without slipping, then its kinetic energy can be expressed as the sum of the translational kinetic energy of its center of mass plus the rotational kinetic energy about the center of mass. The angular velocity is of course related to the linear velocity of the center of mass, so the energy can be expressed in terms of either of them as the problem dictates, such as in the rolling of an object down an incline. Note that the moment of inertia used must be the moment of inertia about the center of mass. If it is known about some other axis, then theparallel axis theorem may be used to obtain the needed moment of inertia.
What are the two basic kinds of kinetic energy?
Linear and rotational
What is the name given to the type of energy that noisy things have?
First of all, you worded the question poorly but I'll answer it the best that I can. If you are referring to the energy that is producing the sound it is vibrational energy. Either some potential energy(eg. gravity) was converted in kinetic energy(eg. motion), or there are inefficiencies which cause some of the work being done on/by the system to be converted back to kinetic energy. Within Kinetic Energy there are different types (translational, vibrational, rotational, etc.) and any of them can be wasted in inefficient systems. The short answer: Kinetic Energy.
What transforms rotational kinetic energy into electricity?
