2. kinetic energy: due to it being transferred through collisions
Sveta_85 [38]3 years ago
4 0
Mechanical energy - this can be either kinetic or potential and has to do with the energy of position and motion of an object

Kinetic energy - this has to do with the speed of an object and how much mass it has; basically how the object is moving

Potential energy - 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

Electrical energy - this is energy that is transferred by the movement of electrons through a conductor: the electrons create a current

Light energy - this is radiant energy from the sun; it's the only kind of energy we can see with our eyes

Thermal energy - this type of energy can be transferred in three different ways: 1) direction contact through collisions (also called conduction), 2) through a fluid making a current created by less dense fluids floating and more dense fluids sinking (also called convection), and 3) by waves traveling with or without a medium (also called radiation)

Sound energy - this type of energy travels through vibrations on waves

Chemical energy - this type of energy is often found in things like batteries or food

Nuclear energy - this is the energy found in the nucleus of an atom

Energy conversions - this is the term used when energy changes from one form to another

Estimate how long it took King Kong to fall straight down from the top of the Empire State Building (380 m high). Express your a
ankoles [38]

Answer:

It will take 8.80 sec to fall from the building

Explanation:

We have given height pf the state building h = 380 m

Initial velocity will be 0 m /sec

So u = 0 m/sec

Acceleration due to gravity g=9.8m/sec^2

We have to find the fall time

According to second equation of motion h=ut+\frac{1}{2}gt^2

So 380=0\times t+\frac{1}{2}\times 9.8\times t^2

t^2=77.55

t = 8.80 sec
