FAQ HUB

Frequently Asked Physics Questions & Formulas

Q1What is Newton’s Second Law of Motion Formula?

F = ma: The net force acting on an object equals its mass times its acceleration. Force is measured in Newtons (N), mass in kg, and acceleration in m/s². For example, applying a 20 N force to a 5 kg mass produces an acceleration of 4 m/s².

Q2What are the SUVAT Kinematic Equations in physics?

SUVAT equations describe motion under constant acceleration: v = u + at, s = ut + ½at², v² = u² + 2as, and s = ½(u + v)t. Variables stand for: s = displacement, u = initial velocity, v = final velocity, a = acceleration, t = time.

Q3How does Ohm’s Law Formula (V=IR) work in electrical circuits?

V = IR states that voltage equals current multiplied by resistance. Voltage (V) is in Volts, current (I) in Amperes, and resistance (R) in Ohms (Ω). For example, a 2 A current through a 10 Ω resistor requires 20 Volts.

Q4What is the Wave Equation Formula v = fλ?

The wave equation is v = fλ (wave speed = frequency × wavelength). Wave speed (v) is measured in m/s, frequency (f) in Hz, and wavelength (λ) in meters. For sound at 440 Hz travelling at 343 m/s, λ = 0.78 m.

Q5What is Specific Heat Capacity and its Formula Q = mcΔT?

Q = mcΔT calculates thermal energy transfer. Q is heat energy in Joules, m is mass in kg, c is specific heat capacity (J/kg·K), and ΔT is temperature change. Water has a high specific heat of 4200 J/kg·K.

Q6What does Einstein’s E = mc² Formula mean in Physics?

E = mc² demonstrates mass-energy equivalence. Energy (E) equals mass (m) times the speed of light squared (c² = 9×10¹⁶ m²/s²). Even 1 gram of matter contains an immense 9×10¹³ Joules of energy.
