Question 1

Which physics formulas and principles are utilized in these calculators?

Accepted Answer

Our physics tools implement fundamental laws of classical mechanics and electromagnetism, including Newton's Second Law of Motion (F = m·a), Work-Energy theorem (W = F·d·cosθ), Power equations (P = W/t), and Ohm's Law (V = I·R).

Question 2

How is mechanical work calculated when the force is applied at an angle?

Accepted Answer

Mechanical work depends on the directional alignment of force and displacement. The formula W = F · d · cos(θ) multiplies the force magnitude by distance and the cosine of angle θ between the force vector and the direction of movement.

Question 3

What is the relationship between Voltage, Current, and Resistance in Ohm’s Law?

Accepted Answer

Ohm's Law defines that electrical current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R): I = V / R. Power (P) dissipated by the circuit equals voltage times current: P = V · I.

Question 4

What standard units of measurement (SI units) are expected for physics inputs?

Accepted Answer

Calculators use standard International System of Units (SI): mass in kilograms (kg), acceleration in meters per second squared (m/s²), force in Newtons (N), distance in meters (m), energy in Joules (J), and power in Watts (W).

Question 5

How does the projectile motion calculator determine flight trajectory, height, and range?

Accepted Answer

The calculator resolves launch velocity into horizontal and vertical components, applying kinematic equations under constant downward gravitational acceleration (g = 9.81 m/s²) while assuming negligible air resistance.
