24 sample cards from the Physics deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
Define power and give its formula and SI unit.
Power is the rate of doing work or transferring energy: P = W/t = Fv. Its SI unit is the watt (W = J/s).
Define efficiency and give its formula.
Efficiency is the ratio of useful output energy (or power) to total input energy (or power), expressed as a percentage: Efficiency = (useful output / total input) x 100%.
Why is the efficiency of a real machine always less than 100%?
Because some input energy is always lost as heat, sound, or to friction and other dissipative forces, so useful output is always less than total input.
Define angular displacement, angular velocity, and angular acceleration with their units.
Angular displacement (theta) is the angle swept, in radians. Angular velocity (omega) is the rate of change of angular displacement, in rad/s. Angular acceleration (alpha) is the rate of change of angular velocity, in rad/s^2.
State the relationships between linear and angular quantities (s, v, a).
s = r.theta; v = r.omega; a (tangential) = r.alpha, where r is the radius of the circular path.
Define centripetal acceleration and give its formula.
Centripetal acceleration is the acceleration directed toward the centre of a circular path: a = v^2/r = r.omega^2.
Define centripetal force and give its formula.
Centripetal force is the net inward force required to keep a body moving in a circle, directed toward the centre: F = mv^2/r = m.r.omega^2.
What provides the centripetal force for (a) a car turning a corner and (b) a planet orbiting the Sun?
(a) Friction between the tyres and the road. (b) The gravitational force between the planet and the Sun.
Define torque (moment of a force) and give its formula and SI unit.
Torque is the turning effect of a force: tau = r F sin(theta) = force x perpendicular distance from the axis. Its SI unit is the newton-metre (N.m).
Define moment of inertia and state what it depends on.
Moment of inertia (I) is the rotational analogue of mass, measuring resistance to angular acceleration: I = sum(m r^2). It depends on the mass of the body and how that mass is distributed about the axis of rotation.
State the rotational form of Newton's second law and the formula for rotational kinetic energy.
Rotational second law: tau = I.alpha (torque = moment of inertia x angular acceleration). Rotational kinetic energy = (1/2)I.omega^2.
Define pressure in a fluid and give the formula for pressure at depth h in a liquid.
Pressure is force per unit area, P = F/A. The pressure due to a liquid column of depth h is P = rho.g.h, where rho is the liquid density.
State Pascal's principle (law).
Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid and to the walls of the container. This is the basis of hydraulic systems.
State Archimedes' principle and the condition for an object to float.
Archimedes' principle: an object immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces. An object floats when the buoyant force equals its weight (i.e., its average density is less than or equal to the fluid's density).
State the equation of continuity for an incompressible fluid.
A1.v1 = A2.v2 (the product of cross-sectional area and fluid speed is constant), meaning fluid speeds up where the pipe narrows.
State Bernoulli's equation and what each term represents.
P + (1/2)rho.v^2 + rho.g.h = constant along a streamline. The terms are static pressure, dynamic (kinetic) pressure per unit volume, and pressure due to height (potential), for an ideal incompressible non-viscous fluid.
According to Bernoulli's principle, how does fluid pressure relate to fluid speed?
Where the speed of a fluid is high, its pressure is low, and where the speed is low, its pressure is high (for a horizontal flow). This explains aerofoil lift and the spin of balls.
Define viscosity and state how it changes with temperature for liquids and gases.
Viscosity is a fluid's resistance to flow (internal friction between layers). For liquids, viscosity decreases as temperature rises; for gases, viscosity increases as temperature rises.
State Stokes' law for the drag force on a small sphere moving through a viscous fluid.
F = 6.pi.eta.r.v, where eta is the coefficient of viscosity, r is the sphere's radius, and v is its velocity relative to the fluid.
Define terminal velocity and state the condition at which it is reached.
Terminal velocity is the constant maximum velocity attained by a body falling through a fluid, reached when the net force is zero (weight = buoyant force + viscous drag), giving zero acceleration.
Define surface tension and give one everyday example of its effect.
Surface tension is the force per unit length acting along the surface of a liquid that makes it behave like an elastic stretched membrane, due to cohesive forces. Example: water droplets forming spherical shapes, or insects walking on water.
Define Simple Harmonic Motion (SHM) and state its defining condition.
SHM is oscillatory motion in which the restoring force (and acceleration) is directly proportional to the displacement from the mean position and always directed toward it: a = -omega^2 x.
Give the formula for the time period of a mass-spring system and a simple pendulum.
Mass-spring: T = 2.pi.sqrt(m/k). Simple pendulum: T = 2.pi.sqrt(L/g), where L is the pendulum length and g is gravitational acceleration.
In SHM, at what positions are velocity and acceleration maximum and minimum?
Velocity is maximum at the mean (equilibrium) position and zero at the extremes. Acceleration is maximum at the extreme positions and zero at the mean position.
What this deck covers
The Physics deck follows the Pharm-D Admission Test Physics syllabus — 10 chapters and 34 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 6.1 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 164 characters, which is long enough to carry the reasoning and short enough to say out loud.
A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.
Physics flashcards FAQ

Yes. The preview here is free to read with no signup, and the full 61-card deck is free inside the Examius app.
What do the Physics cards cover?
They follow the Pharm-D Admission Test Physics syllabus — 10 chapters and 34 topics — so the questions track what is actually examinable.
How should I use these flashcards?
Read the syllabus first so you know the shape of the subject, then drill the deck. Examius schedules each card with spaced repetition, so cards you keep missing come back sooner and ones you know drift further apart.
