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.
What is the difference 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 work and give its formula.
Work is done when a force moves a body through a displacement: W = F·S·cosθ, where θ is the angle between force and displacement. SI unit: joule (J).
When is the work done by a force zero, maximum, and negative?
Zero when θ = 90°; maximum (positive) when θ = 0°; negative when θ = 180° (force opposes motion).
Write the formulas for kinetic energy and gravitational potential energy.
Kinetic energy KE = ½mv²; gravitational potential energy PE = mgh.
State the work-energy theorem.
The net work done on a body equals the change in its kinetic energy: W = ½mvf² − ½mvi².
State the law of conservation of energy.
Energy can neither be created nor destroyed; it only changes from one form to another, and the total energy of an isolated system remains constant.
For a body falling freely, how do KE and PE change while total energy stays constant?
As the body falls, PE decreases and KE increases by an equal amount, keeping total mechanical energy (KE + PE) constant.
What is meant by absolute (gravitational) potential energy?
It is the work done in bringing a body from infinity to a point in a gravitational field. U = −GMm/r, taken as zero at infinity (hence negative for a bound body).
Write the formula for escape velocity and its approximate value from Earth.
vesc = √(2GM/R) = √(2gR) ≈ 11.2 km/s for Earth.
Define power and give its formula and SI unit.
Power is the rate of doing work: P = W/t = F·v. SI unit: watt (W), where 1 W = 1 J/s.
Define efficiency and how it is calculated.
Efficiency = (useful output energy or power / total input energy or power) × 100%. It is always less than 100% due to energy losses.
Define angular displacement and its SI unit.
Angular displacement is the angle swept by a rotating body about its axis. SI unit: radian (rad). One revolution = 2π rad.
Define angular velocity and give the relation between linear and angular velocity.
Angular velocity ω = Δθ/Δt (rad/s). Linear velocity v = rω, where r is the radius.
Write the relation between linear acceleration and angular acceleration.
a = rα, where α is angular acceleration (rad/s²) and r is the radius of the circular path.
Define centripetal force and give its formula.
Centripetal force is the net inward force keeping a body in circular motion, directed toward the centre: Fc = mv²/r = mrω².
Define centripetal acceleration and give its formula.
Centripetal acceleration is directed toward the centre of the circle: ac = v²/r = rω².
Define moment of inertia and its SI unit.
Moment of inertia is the rotational analogue of mass, the resistance to angular acceleration: I = Σmr². SI unit: kg·m².
Give the moment of inertia of a solid sphere, a thin hoop/ring, and a solid disc about their central axes.
Solid sphere: I = (2/5)MR². Hoop/ring: I = MR². Solid disc/cylinder: I = ½MR².
Write the formula for rotational kinetic energy and angular momentum.
Rotational KE = ½Iω²; angular momentum L = Iω. Unit of L: kg·m²/s.
Define viscosity and name the coefficient that measures it.
Viscosity is the internal friction or resistance to flow between layers of a fluid. It is measured by the coefficient of viscosity η (unit: Pa·s or N·s/m²).
State Stokes' law for the drag force on a sphere moving through a fluid.
F = 6πηrv, where η is viscosity, r the radius of the sphere, and v its velocity.
Define terminal velocity and write its formula for a sphere falling in a fluid.
Terminal velocity is the constant maximum velocity attained when drag plus buoyancy balance weight: vt = (2r²(ρ − σ)g)/(9η), where ρ is sphere density and σ fluid density.
State Bernoulli's equation and the principle it expresses.
P + ½ρv² + ρgh = constant. It states that for an ideal fluid, the sum of pressure energy, kinetic energy, and potential energy per unit volume stays constant; where speed is high, pressure is low.
Define a progressive (travelling) wave and write the wave speed relation.
A progressive wave transfers energy through a medium without transporting the medium itself. Wave speed v = fλ, where f is frequency and λ is wavelength.
What this deck covers
The Physics deck follows the UVAS DVM Admission Test Physics syllabus — 13 chapters and 43 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 3.8 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 115 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 UVAS DVM Admission Test deck?
50 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these UVAS DVM Admission Test flashcards free?
Yes. The preview here is free to read with no signup, and the full 50-card deck is free inside the Examius app.
What do the Physics cards cover?
They follow the UVAS DVM Admission Test Physics syllabus — 13 chapters and 43 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.
