DownloadWhat is the first law of thermodynamics?
Flip card
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed (also known as the law of energy conservation).
What is Youngs modulus?
Flip card
Youngs modulus is a measure of the stiffness of a solid material and is defined as the ratio of stress to strain in the linear elasticity regime of a uniaxial deformation.
What is Kirchhoffs Voltage Law (KVL)?
Flip card
Kirchhoffs Voltage Law states that the sum of all electrical voltages around any closed network is zero.
What is the purpose of a transformer in an electrical circuit?
Flip card
A transformer is used to increase (step-up) or decrease (step-down) AC voltages in an electrical circuit.
Define the term fluid mechanics.
Flip card
Fluid mechanics is the branch of physics that studies the behavior of fluids (liquids and gases) and the forces on them.
What is Pascals principle?
Flip card
Pascals principle states that a pressure change at any point in an incompressible, confined fluid is transmitted undiminished throughout the fluid.
What is the difference between scalar and vector quantities?
Flip card
Scalar quantities have magnitude only (e.g., temperature, mass), while vector quantities have both magnitude and direction (e.g., velocity, force).
What is the unit of electrical resistance?
Flip card
The unit of electrical resistance is the ohm (Ω).
