What is the relationship between a body's acceleration, mass, and net force according to Newton's second law of motion?
What is the relationship between a body's acceleration, mass, and net force according to Newton's second law of motion?
- Acceleration plus mass equals net force
- Acceleration divided by mass equals net force
- Acceleration multiplied by mass equals net force (correct)
- Acceleration minus mass equals net force
According to Newton's first law of motion, what happens to a body in the absence of a force?
According to Newton's first law of motion, what happens to a body in the absence of a force?
- It decelerates until it stops
- It changes direction randomly
- It remains at rest or continues at a constant speed in a straight line (correct)
- It accelerates indefinitely
According to Newton's third law of motion, what is the relationship between the forces exerted by two bodies on each other?
According to Newton's third law of motion, what is the relationship between the forces exerted by two bodies on each other?
- Forces have the same magnitude but opposite directions (correct)
- Forces have different magnitudes and opposite directions
- Forces have different magnitudes and same direction
- Forces have the same magnitude and same direction
