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 torque (moment of force).
Torque is the turning effect of a force about a point or axis; τ = rF sinθ, where r is the moment arm and θ the angle between r and F. SI unit: N·m.
State the first condition of equilibrium.
The vector sum of all forces acting on a body is zero: ΣF = 0 (i.e., ΣFx = 0 and ΣFy = 0).
State the second condition of equilibrium.
The vector sum of all torques acting on the body about any point is zero: Στ = 0.
Distinguish between translational and rotational equilibrium.
Translational equilibrium: net force is zero (no linear acceleration); rotational equilibrium: net torque is zero (no angular acceleration).
Define displacement and how it differs from distance.
Displacement is the shortest straight-line vector from initial to final position (has direction); distance is the total path length (a scalar).
Distinguish between average velocity and instantaneous velocity.
Average velocity = total displacement/total time; instantaneous velocity is the velocity at a particular instant (limit of average velocity as time interval approaches zero).
Define acceleration and give its SI unit.
Acceleration is the rate of change of velocity, a = Δv/Δt; SI unit is m/s². It is a vector quantity.
State the three equations of uniformly accelerated motion.
vf = vi + at; S = vi t + ½ a t²; 2aS = vf² − vi².
State Newton's first law of motion.
A body at rest remains at rest and a body in uniform motion continues in a straight line at constant speed unless acted upon by a net external force (law of inertia).
State Newton's second law of motion.
The rate of change of momentum of a body is directly proportional to the applied net force and is in the direction of that force; F = ma.
State Newton's third law of motion.
To every action there is an equal and opposite reaction; the action and reaction forces act on two different bodies.
Define linear momentum and give its formula and SI unit.
Linear momentum is the product of mass and velocity, p = mv; it is a vector with SI unit kg·m/s. It is the quantity of motion of a body.
State the law of conservation of linear momentum.
If no external force acts on a system, the total linear momentum of the system remains constant: total momentum before collision = total momentum after collision.
Distinguish between elastic and inelastic collisions.
In an elastic collision both momentum and kinetic energy are conserved; in an inelastic collision momentum is conserved but kinetic energy is not.
Define impulse and state its relation to momentum.
Impulse = force × time of contact = FΔt; it equals the change in momentum: FΔt = Δp. SI unit: N·s.
What is projectile motion?
Two-dimensional motion of a body under gravity after being projected, having a constant horizontal velocity and a vertically accelerated motion (a = g downward).
For a projectile launched at angle θ with speed v, what are the initial horizontal and vertical velocity components?
Horizontal: vx = v cosθ (constant); Vertical: vy = v sinθ (changes due to gravity).
Give the formulas for time of flight, maximum height, and range of a projectile launched at angle θ with speed v.
Time of flight T = (2v sinθ)/g; Maximum height H = (v² sin²θ)/(2g); Range R = (v² sin2θ)/g.
At what launch angle is the range of a projectile maximum, and why?
At 45°, because R = (v² sin2θ)/g is maximum when sin2θ = 1, i.e., 2θ = 90°.
Define work and state when work done by a force is zero.
Work W = F·d = Fd cosθ (force times displacement in force direction). Work is zero when θ = 90° (force perpendicular to displacement) or when displacement is zero. SI unit: joule (J).
Define kinetic energy and give its formula.
Kinetic energy is the energy possessed by a body due to its motion; K.E. = ½ m v².
State the work-energy principle (theorem).
The net work done on a body equals the change in its kinetic energy: W = ΔK.E. = ½ m vf² − ½ m vi².
Define gravitational potential energy and give its formula.
It is the energy stored in a body due to its position/height in a gravitational field; P.E. = mgh.
Define power and give its SI unit and formula.
Power is the rate of doing work, P = W/t = F·v; SI unit is the watt (W), where 1 W = 1 J/s.
What this deck covers
The Physics deck follows the FSc Pre-Medical Physics syllabus — 12 chapters and 41 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 5.0 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 119 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
How many Physics flashcards are in this FSc Pre-Medical deck?
60 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these FSc Pre-Medical flashcards free?
Yes. The preview here is free to read with no signup, and the full 60-card deck is free inside the Examius app.
What do the Physics cards cover?
They follow the FSc Pre-Medical Physics syllabus — 12 chapters and 41 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.
