Write 3 – 4 sentences to describe the kinetic and potential energy of a particle and how the two terms are related.
1 answer:
Potential energy is position relative, and kinetic energy is motion relative. The primary relationship between the two is their ability to transform into each other. In other words, potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and then back again.
Potential energy defined as :
The energy stored in a body due to either its position or change in shape is known as potential energy. Water stored in a reservoir is an example of potential energy.
PE=mgh
where,
PE is the potential energy
m is the mass of the body
g is the acceleration due to gravity
h is the height above the surface of the earth
Kinetic energy is defined as :
Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.
Kinetic Energy Formula:
For the Kinetic formula, Ek, is certainly the energy of a mass, m, motion, of course, is v2.
KE =
KE = Kinetic energy
m = mass of the body
v = velocity of the body
What are the similarities between potential energy and kinetic energy?
One of the most important similarities between potential energy and kinetic energy is that they can both be converted into each other's form of energy. When a force is applied to potential energy it converts to kinetic energy. This means that when an object such as a ball is still it has the potential to move.

<em><u>Note: There is no image to take as a reference, so I'm assuming F2 directed to the right and F1 to the left, and F2=2F1</u></em>
Answer:
<em>to the right</em>
Explanation:
<u>Net Force</u>
When several forces are applied to a particle or a system of particles, the net force is the sum of them all, considering each force as a vector. As for the second Newton's law, the total force equals the product of the mass by the acceleration of the system:
If the net force is zero, then the system of particles keeps at rest or at a constant velocity.
The system of particles described in the question consists of two objects of masses m1=M and m2, where
Two forces F1=F and F2 act individually on each object in opposite directions and
We don't get to see any image to know where the forces are applied to, so we'll assume F2 to the right and F1 to the left.
The net force of the system of particles is
The mass of the system is
Thus, the acceleration of the center of mass of the system is
Since F2 is greater than F1, the direction of the acceleration is to the right.
Note: If the forces were opposite than assumed, the acceleration would be to the left
