If a physical property varies with temperature, you can use it to set up a scale to measure temperature. Such a property is a thermometric property. The device that thus measure temperature is called a thermometer. Thermometric Property Thermometer Volume expansion of a gas Gas thermometer Volume expansion of a liquid Laboratory or clinical thermometer Volume expansion of a solid …
Definition: If two bodies A and B are separately in thermal equilibrium with a third body C, then A and B are also in thermal equilibrium with each other. – This implies that it is meaningful to define a quantity (called temperature) that can be used to describe the thermal state of the body. If two bodies have the same …
Heat and Thermal Energy Heat is energy in transit that flows from the hotter body to the colder body. In Physics, “heat” is a flow quantity and not a property of an object. Heat flows into or out of an object. This heat comes from/goes into the heat energy or thermal energy of the object. Thermal energy is one of …

Friction Friction is the force that resists the motion of one surface relative to another with which it is in contact. It is parallel to the contact surfaces and opposite to the direction of motion or impeding motion. Body In Motion Friction between a moving object and its environment plays a crucial role by acting to diminish the object’s velocity. …
When two or more external forces acting on a body produce a net resultant force, i.e, the vector sum of forces is not zero, the forces are unbalanced. Newton’s Second Law Of Motion Newton’s Second Law of Motion says that the resultant force acting on a body produces a net acceleration and causes the body to accelerate in the direction …
Newton’s 3 Laws Of motion Newton’s 3 laws of motion are: We will explore first and third law of motion in this post and the 2nd law of motion in greater details in the subsequent posts. Newton’s First Law Of Motion When two or more external forces acting on a body produce no net resultant force, i.e., vector sum of …
