According to Newton's laws of motion, what happens to an object when it is not acted upon by a force?
- It stays in motion at a constant speed in a straight line (correct)
- It remains at rest
- It changes direction
- It accelerates
When two bodies exert forces on each other, what can be said about the magnitude and direction of these forces?
When two bodies exert forces on each other, what can be said about the magnitude and direction of these forces?
- The forces have different magnitudes and opposite directions
- The forces have the same magnitude and the same direction
- The forces have the same magnitude but opposite directions (correct)
- The forces have different magnitudes but the same direction
What is the relationship between an object's acceleration, mass, and net force?
What is the relationship between an object's acceleration, mass, and net force?
- Acceleration minus mass equals net force
- Acceleration multiplied by mass equals net force (correct)
