if the question is this For which course, certification or exam are you uploading?
and if this is it 1. Motion and Forces:
Distance vs. Displacement:
Distance is the total path length covered; displacement is the straight-line
distance from start to end point.
Speed vs. Velocity:
Speed is how fast an object is moving; velocity is speed in a given direction.
Acceleration:
Acceleration is the rate of change of velocity. a = \frac{{\text{Change in
Velocity}}}{{\text{Time taken}}}a=
Time taken
Change in Velocity
.
2. Laws of Motion:
Newton's First Law:
An object remains at rest or in uniform motion unless acted upon by an external
force.
Newton's Second Law:
F = maF=ma, where FF is the force applied, mm is the mass, and aa is acceleration.
Newton's Third Law:
For every action, there is an equal and opposite reaction.
3. Energy:
Forms of Energy:
Kinetic (motion), Potential (stored), Thermal (heat), Chemical (bonds), Nuclear
(atomic), Electrical, and Light.
Conservation of Energy:
Energy cannot be created or destroyed, only transferred or transformed from one
form to another.
4. Waves and Optics:
Wave Characteristics:
Amplitude (height of wave), Wavelength (distance between peaks), Frequency (number
of waves per second), and Wave Speed (v = \lambda \times fv=λ×f).
Reflection and Refraction:
Reflection is the bouncing back of light waves from a surface; refraction is the
bending of light as it passes from one medium to another.
5. Electricity and Magnetism:
Ohm's Law:
V = IRV=IR, where VV is voltage, II is current, and RR is resistance.
Magnetic Fields:
Magnetic fields are produced by moving charges. The Earth itself acts like a giant
magnet.
6. Thermodynamics:
Laws of Thermodynamics:
1st Law: Energy cannot be created or destroyed, only transferred or transformed.
2nd Law: Heat naturally flows from areas of high temperature to low temperature.
3rd Law: As temperature approaches absolute zero, the entropy of a perfect crystal
approaches a minimum value.
7. Modern Physics:
Quantum Mechanics:
Study of particles at the atomic and subatomic level. Particles can behave as both
waves and particles (wave-particle duality).
Special Relativity:
Einstein's theory that explains the relationship between space and time, especially
concerning high velocities and the speed of light. what would the answer be for the
