Science
Undergoing projectile motion
projectile
Rate of chanc5in velocity with time
Acceleration
Acceleration is constant
Uniformly accelerated Motion (UAM)
Cannot be created or destroyed (Before and After the collision are equal)
Law of conservation
it is the sum of potential energy and kinetic energy.
Mechanical energy
change of momemtum is called?
Impulse
bodies change their momemtum through..
Collision
Energy possessed by an objects by virtue of its motion
Kinetic energy
Energy stored in a stretched
Elastic potential energy
Energy possessed by a object because of its location and position
gravitational potential energy
Is energy possessed by a objects at rests
Potential energy
change in internal energy
First law of thermodynamics
energy of a substance is the sum if the molecular kinetic energy
Internal energy
Heat flows from higher to lower (It does not require any external energy to occur)
Spontaneous
lover to higher (it needs mechanical energy to occur)
non-spontaneous
heat transfer (Electromagnetic)
Conduction
Transfer of heat from one location(fluids)
Convection
the transfer of heat energy through space by electromagnetic radiation.
Radiation
is made of waves of different frequencies.
Electromagnetic radiation
needs no specific direction
scalar
needs a specific direction
Vector
When two objects try to pull each other this is?
gravitational force
Constant velocity
Uniform motion
Is a facility where electricity is generated from energy source
Powerplant
is device that converts mechanical energy into electrical energy
Generator
Are power cables that carries high voltage electricity over long distances
Transmission lines
carrier electricity at lower voltage
Distribution lines
it is a rotating shaft with blades
Turbine
either increases or decreases the voltage
transformer
is an encounter between two objects resulting in exchange of impulse and momentum
Collision
bounce off after collision
Elastic collision
sitck together after collision
Inelastic collisions
heat is produced using a combination process. Makes fuel and an oxidizer for that fuel like air.
Combustion engine
burning of fuel takes place outside the engine
External combustion engine
burning fuel takes place inside the cylinder or turbine engine
internal combustion engine
product of the mass of a particle and its velocity
momemtum
heat flows from a hotter object to a cooler object
Heat pump
amount of matter an object contains
Mass
force gravity applies to an object
Weight
