What is the relationship between different forms of energy?
Most forms of energy can be transformed into other forms
. When you turn a toaster on, what happens to the electrical energy? The electrical energy is transformed to thermal energy.
What are the different forms of energy quizlet?
- mechanical energy (kinetic or potential) kinetic or potential energy associated with the motion or position of an object.
- heat energy (thermal) …
- light energy (electromagnetic energy) …
- sound energy. …
- nuclear energy. …
- electrical energy. …
- chemical energy.
What is the relationship between different forms of energy?
When the kinetic energy
of an object changes
, energy is transferred to or from the object. When the motion energy of an object changes, there is inevitably some other change in energy at the same time. Kinetic energy may take different forms (e.g., energy in fields, thermal energy, energy of motion).
When you turn a toaster on what happens to the electrical energy?
1. A toaster draws electric current (electrical energy) from a wall outlet and
converts these moving electric charges into heat (thermal energy) in the filaments that turn red hot to cook your toast
.
What is the relationship between work and energy quizlet?
Work-Energy Theorem:
The work done on an object is equal to it’s change in kinetic energy
.
What are the four forms of energy?
Energy exists in many different forms. Examples of these are:
light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy
and so on. Each form can be converted or changed into the other forms.
What are the 10 energy types?
- Kinetic Energy. Kinetic energy is energy of motion. …
- Potential Energy. …
- Mechanical Energy. …
- Nuclear Energy. …
- Ionization Energy. …
- Chemical Energy. …
- Electromagnetic Energy. …
- Thermal Energy.
What are the two types of energy quizlet?
- Kinetic Energy. The energy of motion.
- Energy. The ability to do work or create change.
- Potential Energy. Stored energy.
- Gravitational Potential Energy. Energy due to position. …
- Elastic Potential Energy. …
- Chemical Energy. …
- Nuclear Energy. …
- Electromagnetic energy (radiant)
What are the two main types of energy?
- Potential energy.
- Kinetic energy.
Which of the following are forms of kinetic energy coiled spring?
Elastic energy
is a form of potential energy that is stored in an elastic object – such as a coiled spring or a stretched elastic band.
What is the best example of a device that converts electrical energy to light and sound?
For example,
a bulb
converts electrical energy into light energy and a speaker converts it into sound energy.
When you turn a toaster on what happens to the electrical energy quizlet?
When you turn a toaster on, what happens to the electrical energy?
The electrical energy is transformed to thermal energy
.
Is a device that converts electrical energy into mechanical energy?
Electric motor
: An electric motor is an electrical device that converts electrical energy to mechanical energy.
Which best describes the work-energy theorem?
An work-energy theorem describes
the relationship between work and energy
. The work-energy theorem states that whenever work is done, energy changes. The net force and net work are zero, and, according to the work-energy theorem KE=0; the kinetic energy dosen’t change.
What is the relationship between work and energy?
The relationship between work and Kinetic Energy, also called the Work-Energy theorem, states that
the work done by the sum of all the force acting over any particle/ object is equal to the change in the Kinetic Energy of the particle.
Which increases kinetic energy the most?
It turns out that an object’s
kinetic energy increases as the square of its speed
. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Thus a modest increase in speed can cause a large increase in kinetic energy.
