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 starts accelerating
- It moves in a circular path
- It remains at rest or continues to move at a constant speed in a straight line (correct)
- It slows down gradually
According to Newton's second law of motion, what is the relationship between a body's acceleration, mass, and net force acting on it?
According to Newton's second law of motion, what is the relationship between a body's acceleration, mass, and net force acting on it?
- The body's acceleration is directly proportional to the net force
- The body's acceleration multiplied by its mass is equal to the net force (correct)
- The body's acceleration is equal to the net force
- The body's acceleration is inversely proportional to its mass
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 the same magnitude and same direction
- The forces have different magnitudes and opposite directions
- The forces have the same magnitude but opposite directions (correct)
- The forces have different magnitudes and same direction
