Physics (NEET-UG Academic Component) flashcards for AFMC / NEET-linked AFMC Admission

24 of 66 cards from the Physics (NEET-UG Academic Component) deck — real questions with worked answers.

1. In kinematics, what does the area under a velocity-time graph represent, and what does its slope represent?

   The area under a v-t graph gives displacement; the slope of a v-t graph gives acceleration.

2. State the three equations of motion for uniform acceleration (constant a).

   v = u + at; s = ut + ½at²; v² = u² + 2as (where u = initial velocity, v = final velocity, s = displacement, t = time).

3. For projectile motion launched at angle θ with speed u, give the formulas for time of flight, maximum height, and horizontal range.

   Time of flight T = 2u sinθ/g; Maximum height H = u²sin²θ/2g; Range R = u²sin2θ/g. Range is maximum at θ = 45°.

4. State Newton's three laws of motion.

   1st: A body remains at rest or in uniform motion unless acted on by a net external force (inertia). 2nd: F = dp/dt = ma. 3rd: To every action there is an equal and opposite reaction.

5. Define impulse and state the impulse-momentum theorem.

   Impulse J = F·Δt (force × time); it equals the change in momentum: J = Δp = mv − mu. Impulse is a vector measured in N·s.

6. Distinguish between static, limiting, and kinetic friction. Which coefficient is larger?

   Static friction is self-adjusting up to a maximum (limiting friction = μₛN); kinetic friction (μₖN) acts during relative motion. μₛ > μₖ, so it takes more force to start motion than to keep it moving.

7. What is the work-energy theorem?

   The net work done by all forces on a body equals its change in kinetic energy: W_net = ΔKE = ½mv² − ½mu².

8. State the law of conservation of mechanical energy and give the condition for it to hold.

   In a system where only conservative forces act, total mechanical energy (KE + PE) remains constant. It does not hold when non-conservative forces (e.g., friction) are present.

9. Define power and give its formula in terms of force and velocity. What is its SI unit?

   Power is the rate of doing work: P = W/t = F·v (dot product). SI unit is the watt (W = J/s). 1 horsepower = 746 W.

10. Compare elastic and inelastic collisions in terms of what is conserved.

    In both, momentum is conserved. In an elastic collision, kinetic energy is also conserved; in an inelastic collision, kinetic energy is NOT conserved (some converts to heat/deformation). In a perfectly inelastic collision the bodies stick together.

11. Define moment of inertia and give its formula for a system of particles.

    Moment of inertia is the rotational analogue of mass, measuring resistance to angular acceleration: I = Σmᵢrᵢ², where rᵢ is the perpendicular distance from the axis. SI unit: kg·m².

12. State the moment of inertia of a solid sphere, a hollow sphere, a solid cylinder/disc, and a thin ring about their central axes.

    Solid sphere: (2/5)MR²; Hollow (thin) sphere: (2/3)MR²; Solid cylinder/disc: (1/2)MR²; Thin ring/hoop: MR².

13. State the parallel axis theorem.

    I = I_cm + Md², where I_cm is the moment of inertia about an axis through the center of mass and d is the perpendicular distance to the parallel axis.

14. What is torque, and how is it related to angular momentum and to angular acceleration?

    Torque τ = r × F. It equals the rate of change of angular momentum: τ = dL/dt, and for rigid bodies τ = Iα. When net external torque is zero, angular momentum L is conserved.

15. State Newton's law of universal gravitation.

    Every mass attracts every other mass with a force F = G·m₁m₂/r², directed along the line joining them, where G = 6.67 × 10⁻¹¹ N·m²/kg².

16. Give the formulas for orbital velocity and escape velocity from a planet's surface.

    Orbital velocity (close orbit) v₀ = √(gR) = √(GM/R); Escape velocity vₑ = √(2gR) = √(2GM/R). Thus vₑ = √2 · v₀. For Earth, vₑ ≈ 11.2 km/s.

17. State Kepler's three laws of planetary motion.

    1st (Law of Orbits): planets move in ellipses with the Sun at one focus. 2nd (Law of Areas): the line joining planet to Sun sweeps equal areas in equal times (constant areal velocity). 3rd (Law of Periods): T² ∝ a³ (square of period proportional to cube of semi-major axis).

18. How does acceleration due to gravity g vary with height h and depth d (for h, d << R)?

    At height: g_h = g(1 − 2h/R). At depth: g_d = g(1 − d/R). g is maximum at the surface and zero at the center of the Earth.

19. Define stress, strain, and Young's modulus.

    Stress = restoring force per unit area (F/A); Strain = fractional change in dimension (ΔL/L), dimensionless; Young's modulus Y = longitudinal stress/longitudinal strain = (F·L)/(A·ΔL). SI unit of Y: pascal (Pa).

20. State Hooke's law and define the elastic limit.

    Hooke's law: within the elastic limit, stress is directly proportional to strain (stress = modulus × strain). The elastic limit is the maximum stress up to which a body returns to its original shape after the load is removed.

21. State Pascal's law and the principle behind a hydraulic lift.

    Pascal's law: pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid and the walls. A hydraulic lift uses this to multiply force: F₂/F₁ = A₂/A₁.

22. State Bernoulli's theorem for ideal fluid flow.

    For steady, incompressible, non-viscous flow: P + ½ρv² + ρgh = constant along a streamline (pressure energy + kinetic energy + potential energy per unit volume is conserved).

23. Define surface tension and state the excess pressure inside a liquid drop and a soap bubble.

    Surface tension is force per unit length acting along a liquid surface (N/m). Excess pressure inside a drop: ΔP = 2T/r; inside a soap bubble (two surfaces): ΔP = 4T/r.

24. State Stokes' law and define terminal velocity.

    Viscous drag on a sphere of radius r moving with velocity v in a fluid of viscosity η: F = 6πηrv. Terminal velocity is the constant maximum velocity attained when net force is zero: v_t = 2r²(ρ−σ)g/9η.
