What is the definition of energy in scientific terms? It’s the k 12 plz help mehhh

Physics

Aleks [24]4 years ago
3 0

Explanation:

In science energy is simply defined as the ability to do work. Anything that causes work to be done must have expended some form of energy .

Energy is broadly categorized into two parts;

  • Kinetic energy is the energy due to the motion of a body.
  • Potential energy is the energy at rest in a body.
  • Other forms of energy stems these two forms of energy.
  • Thermal energy, mechanical energy are examples of kinetic energy.
  • Chemical energy, gravitational energy are examples of potential energy.
  • Energy is neither created nor destroyed but transformed from one form to another according to the law of conservation of energy.

is it possible for the gravitational force between two 50-kg objects to be less than the gravitational force between a 59-kg obj
Eva8 [605]

OF COURSE !  

The gravitational force between two objects doesn't ONLY depend on the product of their masses.  It also depends on the distance between them.

I'm not even going to work out the numbers for my example.  I'm just going to state without proof that at the top of the 2nd frame, the gravitational force between you and your bowling ball is greater than the gravitational force between you and the whole darn Andromeda galaxy !  My reasoning is based on the fact that your bowling ball is maybe 1 foot from your center of mass, whereas the Andromeda galaxy is more like 2.5 million light years from it.  That right there is going to give your bowling ball a big advantage when it comes to gravity !

____ is the force that moves people to behave, think, and feel the way they do, resulting in behavior that is energized, directe
pogonyaev

Answer:

Motivation

Explanation:

Motivation is the force that directs one's behavior. This force is required for repeated actions. There are two types of motivation:

Intrinsic

This type of motivation is comes from the individual

Extrinsic

This type of motivation is comes from an external influence.

Both conscious and unconscious factors influence motivation.

What happens when visible light strikes a surface?
Amiraneli [1.4K]
Absorption: 

<span>If the wavelength of the light happens to match the distance between two electron levels in the material, it can be absorbed. Light disappears and its energy becomes part of the heat energy of the material. </span>

<span>Metals have so many free electrons that all wavelengths are absorbed -- they are opaque to xrays, visible light, radio waves, everything. </span>
<span>Pigments have specific electron gaps that absorb only the light of a specific wavelength, which we see as color </span>
<span>Transparent materials do not happen to have any gaps between electron levels that match any of the wavelengths of visible light. </span>

Derive the dimension of Power ​
stellarik [79]

Answer:

The dimension of power is energy divided by the time or [ML^2T^-3]

Explanation:

Power =\frac {Work Done}{Time}

We can derive Dimensions of Power from both formula.

Power = Force * Velocity

As,

Force = mass * acceleration

Therefore, Dimensions of

Force = [M]*[LT^-2] = [MLT^-2]

Since,

Velocity = \frac{Length}{Time}

Now, Dimension of

Velocity = [LT^-1]

We have Both Dimensions,Now we can derive Dimensions Of Power,

Power = Force * Velocity

Power =[MLT^-2] * [LT^-1]

Power =[ML^2T^-3]

Two 1.1 kg masses are 1 m apart (center to center) on a frictionless table. Each has +10 JC of charge. What is the initial accel
sweet-ann [11.9K]

Answer:

acceleration = 0.8181 m/s²

Explanation:

given data

mass = 1.1 kg

apart d = 1 m

charge q = 10 μC

to find out

What is the initial acceleration

solution

we know that acceleration is

acceleration = \frac{force}{mass}   .................1

here force = k \frac{q1q2}{r^2}

here q1 q2 is charge and r is distance and Coulomb constant k = 9 × 10^{9} Nm²/C²

force = 9*10^{9} \frac{(10*10^{-6})^2}{1^2}

force = 0.9 N

so  from equation 1

acceleration = \frac{0.9}{1.1}

acceleration = 0.8181 m/s²
