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 remains at rest or continues at a constant speed in a straight line (correct)
- It accelerates in a straight line
- It moves in a circular path
- It decelerates in a straight line
What happens if two bodies exert forces on each other according to Newton's laws of motion?
What happens if two bodies exert forces on each other according to Newton's laws of motion?
- The forces have the same magnitude and same direction
- The forces have the same magnitude but opposite directions (correct)
- The forces have different magnitudes and opposite directions
- The forces have different magnitudes and same direction
What is the relationship between the net force on a body and its acceleration and mass?
What is the relationship between the net force on a body and its acceleration and mass?
- The net force is independent of the body's acceleration
- The net force is inversely proportional to the body's mass
- The net force is equal to the square of the body's acceleration
- The net force equals the body's acceleration multiplied by its mass (correct)
