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 moves in a circular path
- It remains at rest or in motion at a constant speed in a straight line (correct)
- It accelerates indefinitely
- It stops moving immediately
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?
- Acceleration minus mass equals the net force
- Acceleration plus mass equals the net force
- Acceleration divided by mass equals the net force
- Acceleration multiplied by mass equals the net force (correct)
What is the magnitude and direction of the forces exerted by two bodies on each other, according to Newton's third law of motion?
What is the magnitude and direction of the forces exerted by two bodies on each other, according to Newton's third law of motion?
- 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 opposite directions
- The forces have different magnitudes and same direction
