Heat Energy II: Thermal Expansion

Heat Energy II: Thermal Expansion

Expansivity or Expansion is the amount a material expands or contracts per unit length due to a one-degree change in temperature. CONTENT CONCEPT OF EXPANSIVITY THERMAL EXPANSIVITY CONSEQUENCES AND APPLICATION OF EXPANSION   CONCEPT OF EXPANSIVITY Thermal expansivity is the tendency of matter to change in volume in response to a change in temperature. It…

Heat Energy I: Heat Transfer

Heat Energy I: Heat Transfer

Heat is defined in physics as the transfer of heat energy over well-defined boundaries around a thermodynamic system. Thermodynamic free energy is the amount of work that a thermodynamic system can perform. CONTENT TRANSMISSION OF HEAT METHODS OF HEAT TRANSFER CONDUCTION CONVECTION RADIATION   TRANSMISSION OF HEAT Heat transfer, any or all of several phenomena,…

HEAT ENERGY AND TEMPERATURE

HEAT ENERGY AND TEMPERATURE

Heat energy is transferred from one body to another due to temperature differences. If two bodies of different temperatures are brought together, the energy will be transferred from the hotter body to the colder body, that is, the heat flow. The effect of this energy transfer is usually but not always, that the temperature of…

RELATIONSHIP BETWEEN WORK AND POWER

RELATIONSHIP BETWEEN WORK AND POWER

Work is called the process of transferring energy to the movement of an object by applying a force. It is usually expressed as the product of displacement and force. Power is the amount of energy transmitted per unit time. CONTENT CONCEPT OF WORK WORK DONE IN FORCE FIELD INTERCHANGEBILITY OF WORK AND ENERGY CALCULATING WORK…

ENERGY, A TOOL FOR WORK

ENERGY, A TOOL FOR WORK

The word energy comes from ancient Greece. This may be the first time it appeared in Aristotle’s works in the 4th century BC. In the International System of Units (SI), the unit is JOULES, named after JOULES. It is a derived unit. It is equal to that consumed (or work done) by applying a force…

DENSITY, RELATIVE DENSITY CALCULATOR

DENSITY, RELATIVE DENSITY CALCULATOR

Mass and volume determine the physical size, which is called density, and is the characteristic of each substance. Relative density calculator is obtained by the ratio of the density of the substance at a certain temperature to the density of water used as a reference at the same temperature or at a certain other temperature….

CIRCULAR MOTION (REVOLUTION)

CIRCULAR MOTION (REVOLUTION)

In physics, circular motion or revolution is the movement of an object along the circular motion of a circle or along the circular path of rotation. It can be uniform, with a constant rotation angle rate and a constant speed, it can also be non-uniform, with a varying rotation rate. CONTENT MEANING OF CIRCULAR MOTION…

LINEAR MOTION: SPEED AND VELOCITY

LINEAR MOTION: SPEED AND VELOCITY

Speed is the rate at which things move. Velocity is speed with a direction. CONTENT THE CONCEPT OF DISTANCE, SPEED, VELOCITY AND UNIFORM SPEED/VELOCITY CALCULATIONS ON SPEED, VELOCITY AND ACCELARATION VELOCITY – TIME GRAPH   THE CONCEPT OF DISTANCE, SPEED, VELOCITY AND UNIFORM SPEED/VELOCITY Distance: Distance is the total movement of an object without considering…

MOTION: FORCE AND FRICTION

MOTION: FORCE AND FRICTION

Friction is the force that resists the relative movement of solid surfaces, fluid layers, and material elements sliding against each other. CONTENT A) FORCE DEFINITION OF FORCE TYPES B) FRICTION DEFINITION OF FRICTION TYPES OF FRICTION COEFFICIENT OF FRICTION ADVANTAGES AND DISADVANTAGES OF FRICTION WAYS OF REDUCING FRICTION   DEFINITION OF FORCE In physics, force…

MOTION AND IT’S DERIVATIVES

MOTION AND IT’S DERIVATIVES

Motion and movement refers to the change of position in space. Movement indicates a change in position. CONTENT DEFINITION OF MOTION TYPES OF MOTION CAUSE AND EFFECT OF MOTION EQUATION OF MOTION   DEFINITION OF MOTION Movement, in physics, changes in the position or direction of the body over time. Movement along a straight line…
