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 accelerates in the direction of the force
- It remains at rest or continues to move at a constant speed in a straight line (correct)
- It decelerates and comes to a stop
- It moves in a circular path
What does Newton's second law of motion state about the relationship between force, mass, and acceleration?
What does Newton's second law of motion state about the relationship between force, mass, and acceleration?
- The acceleration of a body is directly proportional to its mass and inversely proportional to the net force acting on it
- The acceleration of a body is directly proportional to the net force acting on it and inversely proportional to its mass (correct)
- The acceleration of a body is directly proportional to its mass and the net force acting on it
- The acceleration of a body is directly proportional to the net force acting on it and its mass
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 according to Newton's third law of motion?
- The forces have different magnitudes and same direction
- The forces have different magnitudes and opposite directions
- The forces have the same magnitude but opposite directions (correct)
- The forces have the same magnitude and same direction
