Momentum — definition?

Product of mass and velocity.

Momentum — vector or scalar?

Vector quantity.

Newton’s Second Law — focus?

Force equals rate of change of momentum.

Impulse — formula?

F × Δt = Δp.

Impulse — what does it measure?

Force applied over time.

Conservation of momentum — condition?

No external forces act.

Elastic collision — energy?

Kinetic energy conserved.

Inelastic collision — energy?

Kinetic energy not conserved.

Circular motion — force?

Centripetal force toward center.

Centripetal force — formula?

mv²/r.

Angular displacement — units?

Radians.

Angular velocity — formula?

ω = θ/t.

Instantaneous velocity — in circular motion?

v = rω.

Electric field — effect?

Force on charges.

Electric field strength — symbol?

E.

Potential difference — measures?

Energy transferred per charge.

Electromagnetic induction — cause?

Changing magnetic flux.

Particle kinetic energy — formula?

p²/(2m).
