This can be either kinetic or potential and has to do with the energy of position and motion of an energy- This is related to mechanical energy.It is so because mechanical energy is the sum total of kinetic and potential energy.
This is radiant energy from the sun;it is the only kind of energy we can see with our eyes-It is related to light energy which consists of white light along with its seven colors and these are also electromagnetic radiations.
This is the energy that is transferred by the movement of electrons through a conductor;the electrons create a current-This is related to electric energy.
This type of energy is often found in things like batteries or food-This is related to chemical energy .It is chemical energy which is converted to electrical energy in battery.
This type of energy travels through vibrations on waves-This is related to sound energy which travels in a medium in the form of compressions and rarefactions.
This type of energy is found in the nucleus of an atom-This is related to nuclear energy.For instance the energy produced during nuclear fusion and fission from unstable nuclei.
This is the term used when one type of energy changes from one form to another-This is related to energy conversions.
This type of energy is stored energy;it can be increased by getting into a higher position and/or stretching an object such as a rubber band-This is related to potential energy .It is the energy gained by a body due to its position or change in configurations.
This type of energy can be transferred in three different ways i.e conduction,convection and radiation-We know that heat is transferred in three different ways mentioned above and heat is nothing else than transferred thermal energy.Hence, it is related to thermal energy.
This has to do with the speed of an object and how much mass it has;basically how the how the object is moving-This is related to kinetic energy which is the energy gained by a body due to its motion.
Mathematically it is written as
Elastic potential energy is given by:
Where k is the spring constant in N/m and x is displacement from equilibrium position in m. Evaluating:
A/ The potential energy is stored in the spring is 44.1 J.
Answer:
The cart will accelerate to the left
Explanation:
The cart is initially at rest. In order to understand its motion, we should consider the net force acting on the cart. We have two forces acting on it:
- A force of 7 N to the left
- A force of 5 N to the right
Therefore, the net force is
in the direction of the stronger force (so, to the left).
According to Newton's second law:
a net force different from zero produces an acceleration of the object, in the same direction as the net force. Therefore, the cart will accelerate to the left.
