Circular Motion
The unit used for angular displacement in circular motion.
What is radian?
This quantity is defined as force per unit mass.
What is gravitational field strength?
The type of motion where acceleration is proportional to displacement and directed toward equilibrium.
What is simple harmonic motion?
The SI unit of thermodynamic temperature.
What is kelvin?
Energy of a photon depends on this quantity.
What is frequency?
This quantity describes how quickly angular displacement changes with time.
What is angular velocity?
The law that describes gravitational force between two masses.
What is Newton’s law of gravitation?
The maximum displacement from the equilibrium position.
What is amplitude?
The quantity of substance measured in the SI unit mole.
What is amount of substance?
The experiment that demonstrates the particle nature of light.
What is the photoelectric effect?
The acceleration experienced by an object moving in a circular path that always points toward the centre.
What is centripetal acceleration?
Electric field strength is defined as force per unit of this quantity.
What is charge?
The acceleration equation that describes SHM.
What is acceleration proportional to displacement and opposite in direction?
The equation relating pressure, volume, temperature, and number of moles.
What is the ideal gas equation?
The relationship between photon energy and frequency.
What is E = hf
If the radius of circular motion doubles while speed remains constant, this happens to centripetal acceleration.
What is it halves?
The work done per unit charge in moving a charge between two points.
What is electric potential?
This phenomenon occurs when a system oscillates with large amplitude at a specific driving frequency.
What is resonance?
The internal energy of an ideal gas depends only on this quantity.
What is temperature?
The wavelength associated with a moving particle.
What is de Broglie wavelength?
Explain why a satellite moving in circular orbit does not require thrust to maintain its motion.
What is gravity provides the centripetal force required for circular motion?
Explain why electric field lines never cross.
What is the field direction at a point must be unique?
Explain why damping reduces the amplitude of oscillations over time.
What is energy is dissipated from the system (often as heat)?
State the first law of thermodynamics.
What is the change in internal energy equals heat supplied plus work done on the system?
The principle that explains why electrons occupy discrete energy levels in atoms.
What is quantisation of energy?
