An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.
What is Newton's Second Law of Motion?
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
What is Newton's Third Law of Motion?
For every action, there is an equal and opposite reaction.
What is the theory of relativity?
The theory of relativity, proposed by Albert Einstein, includes the special and general relativity theories that describe the motion of objects and how they are affected by gravitational forces and time dilation.
What is the principle of superposition?
The principle of superposition states that when two or more forces act on a point, the resultant force is the sum of the individual forces.
What is the Doppler Effect?
The Doppler Effect is the change in frequency or wavelength of a wave relative to an observer moving relative to the source of the wave.
What is Archimedes' Principle?
Archimedes' Principle states that a body submerged in fluid experiences a buoyant force equal to the weight of the fluid it displaces.
What is Pascal's Principle?
Pascal's Principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished to every point in the fluid.
What is Hooke's Law?
Hooke's Law states that the force needed to extend or compress a spring is proportional to the distance it is stretched.
What is Kepler's First Law?
Kepler's First Law states that planets move in elliptical orbits, with the sun at one focus of the ellipse.
What is the Heisenberg Uncertainty Principle?
The Heisenberg Uncertainty Principle states that you cannot simultaneously know the exact position and momentum of a particle.
What is Bernoulli's Principle?
Bernoulli's Principle states that as the speed of a fluid increases, the pressure within the fluid decreases.
What is Snell's Law?
Snell's Law relates the angle of incidence and refraction to the refractive indices of the two media.
What are Maxwell's Equations?
Maxwell's Equations are a set of four equations that describe how electric charges and currents create electric and magnetic fields.
What is the Photoelectric Effect?
The Photoelectric Effect occurs when light of a certain frequency causes electrons to be emitted from a material.
