Flashcard: Fundamentals of Classical Physics — 20 carte

Free fall height — calculation method?

Use last second distance and equations of motion.

Point motion graphs — slope indicates?

Velocity of the object.

Object collision — impulse formula?

Impulse equals change in momentum.

Projectile motion — key equations?

Displacement, range, and time formulas.

Acceleration change — sign effect?

Determines speeding up or slowing down.

Moment of inertia — depends on?

Mass distribution relative to rotation axis.

Elastic collision — energy conservation?

Kinetic energy and momentum are conserved.

Angular momentum — formula?

L = Iω, with I = moment of inertia.

Electrostatics — Coulomb's law?

F = k |q₁ q₂| / r².

Electric field — calculation?

E = k |q| / r² from point charges.

Free fall — impact velocity?

v = √(2gh).

Point graphs — area under v-t?

Displacement during interval.

Object collision — inelastic?

Kinetic energy not conserved.

Projectile motion — initial velocity components?

v₀ cos θ and v₀ sin θ.

Acceleration — change in velocity?

a = Δv / Δt.

Moment of inertia — parallel axis theorem?

I = I_cm + Md².

Elastic collision — velocity relation?

Derived from conservation laws.

Angular momentum — external torque?

L changes if torque acts.

F = k |q₁ q₂| / r².

Electric field — superposition?

Sum of individual fields vectorially.
