Free Newton's Laws of Motion Flashcards
Three laws from 1687 still run every mechanics course, rocket launch, and car crash analysis. These cards drill the laws, their formulas, and the classic misconceptions exams test.

QUESTION
Tap the card to reveal the answer
QState Newton's first law.
AAn object stays at rest or in uniform motion unless acted on by a net force (inertia)
QState Newton's second law.
AF = ma — net force equals mass times acceleration
QState Newton's third law.
AFor every action there is an equal and opposite reaction
QWhat is inertia?
AAn object's resistance to changes in its motion — proportional to mass
QWhat is the SI unit of force?
AThe newton (N) = kg·m/s²
QA car brakes suddenly — why do passengers lurch forward?
AFirst law: their bodies continue in motion until a force (seatbelt) stops them
QSame force on two masses — which accelerates more?
AThe smaller mass (a = F/m)
QHow does a rocket accelerate in empty space?
AThird law: it pushes exhaust backward; the exhaust pushes the rocket forward
QWhat is the difference between mass and weight?
AMass is the amount of matter (kg); weight is gravity's force on it (W = mg)
QIf action equals reaction, why does anything move?
AThe paired forces act on DIFFERENT objects, so they don't cancel on either one

- One fact per card. For each law, recall one everyday example — seatbelts, rowing, rockets. The law is the pattern; the example is the memory.
- Rate honestly. After each card, choose Again, Hard, Good, or Easy — the spaced repetition algorithm uses your answer to decide when the card returns, right before you'd forget it.
- A few minutes daily beats marathons. Ten new cards a day is roughly 3,650 a year, retained. Deep dives: How to make flashcards that actually work · The spacing effect, explained · How to study for exams with flashcards.
