thermodynamic equilibrium, condition or state of a thermodynamic system, the properties of which do not change with time and that can be changed to another condition only at the expense of effects on other systems.
How can newton’s second law of motion be represented with an equation?
Newton’s second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration) are both vector quantities. If a body has a net force acting on it, it is accelerated in accordance with the equation.
What is mathematical formulation of second law of motion?
Mathematical Formulation of Second Law of Motion ∝ m × (v – u). The rate of change of momentum ∝ m × (v −u) / t. Or, the applied force, F ∝m × (v −u) / t.
What is open system in thermodynamics?
An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. A closed system, on the other hand, can exchange only energy with its surroundings, not matter.
What do you mean by newton’s second law of motion?
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
What is oblique collision?
Oblique Collision- When the colliding objects do not move along the straight line joining their centres, the collision is said to be oblique collision.
What are 3 types of collisions?
There is a sequence of collisions that occur and each can lead to different and severe injuries.
- First Collision: Vehicle.
- Second Collision: Human.
- The Third Collision: Internal.
What is closed system in thermodynamics?
In the field of thermodynamics, a closed system can be defined as a system in which the exchange of energy (in the form of heat or work, for instance) is allowed but the exchange of matter is not (with respect the surroundings of the system).
