Classical mechanics
This law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
What is Newton's second law of motion
This phase change involves a substance transitioning from a liquid to a gas.
What is evaporation?
What are the two types of electric charges?
The two types of electric charges are positive and negative.
The transition of a substance directly from the solid phase to the gaseous phase without passing through the intermediate liquid phase is called?
Sublimation
He discovered the electron
Who is Joseph John Thomson
This principle states that in the absence of non-conservative forces, the total mechanical energy of a system remains constant.
What is the principle of conservation of mechanical energy
This law of thermodynamics states that energy cannot be created or destroyed, only transformed.
What is the first law of thermodynamics?
What is the SI unit of the charge?
Coulomb.
The distance between two successive crests or troughs of a wave is called?
Wavelength.
He pointed out that gravitation and acceleration are equivalent
Who is Einstein
This principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished throughout the fluid.
What is Pascal’s principle
The device that converts thermal energy into mechanical work.
What is Heat engine?
What is the role of a battery in a circuit?
Battery provides the electric potential or voltage needed to push electric current through the circuit.
Sound travels fastest through ____
Solid
He recognized that the tendency of bodies to move towards one another is what's responsible for holding moon in its orbit
Who is Issac Newton
This property of an object describes its resistance to changes in its state of motion.
What is inertia
thermodynamics, this process occurs at constant pressure.
What is isobaric?
What happens when two opposite magnetic poles are brought near each other?
Opposite magnetic poles attract each other.
What is the speed of sound in dry air at 20 °C?
343 m/s
He proved the that objects of different masses fall at the same rate
Who is Galileo Galilei
This principle states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces.
What is Archimedes' law
This law states that the entropy of an isolated system always increases over time.
What is second law of thermodynamics?
Why are metals typically good conductors of electricity?
They have free electrons that can move easily through the material, allowing electric current to flow.
If the mass of the pendulum is doubled, what happens to the time period?
Remains the same
He developed the uncertainty principle
Who is Warner Heisenberg
