According to Newton's first law of motion, what happens to a body when no force is acting on it?
According to Newton's first law of motion, what happens to a body when no force is acting on it?
- It changes direction randomly
- It stops immediately
- It starts accelerating
- It remains at rest or continues to move at a constant speed in a straight line (correct)
What is the relationship between a body's acceleration, mass, and the net force acting on it according to Newton's second law of motion?
What is the relationship between a body's acceleration, mass, and the net force acting on it according to Newton's second law of motion?
- The body's acceleration is directly proportional to the net force
- The body's acceleration is inversely proportional to the net force
- The body's acceleration multiplied by its mass is equal to the net force (correct)
- The body's mass is not related to its acceleration
According to Newton's third law of motion, what can be said about the forces exerted by two bodies on each other?
According to Newton's third law of motion, what can be said about the forces exerted by two bodies on each other?
- The forces have different magnitudes and opposite directions
- The forces have the same magnitude but opposite directions (correct)
- The forces have the same magnitude and same direction
- The forces have different magnitudes and same direction

Study Notes
Newton's Laws of Motion
- A body remains at rest or in motion at a constant speed in a straight line when no force is acting on it, according to Newton's first law of motion.
Newton's First Law of Motion
- A body remains at rest or in motion at a constant speed in a straight line when no force is acting on it.
Newton's Second Law of Motion
- The acceleration of a body is directly proportional to the net force acting on it and inversely proportional to its mass.
Newton's Third Law of Motion
- When two bodies exert forces on each other, the forces are equal in magnitude and opposite in direction.
Investigation and Explanation
- Newton used the three laws of motion to investigate and explain the motion of celestial bodies, tides, and the behavior of comets.
Publication
- The three laws of motion were first stated by Isaac Newton in his publication "Philosophiæ Naturalis Principia Mathematica".
