Active recall
Quick check
Answer each question before opening the answer.
State Newton's first law of motion.
An object stays at rest, or moves at constant velocity, unless acted on by a resultant force.
What does a zero resultant force mean for an object's motion?
Its motion does not change — it stays still or keeps moving at constant velocity (forces are balanced).
