According to Newton's laws of motion, what happens to an object when the net force acting on it is zero?
According to Newton's laws of motion, what happens to an object when the net force acting on it is zero?
- It remains at rest or continues to move at a constant velocity. (correct)
- It immediately comes to a stop.
- It accelerates indefinitely.
- It moves in a random direction.
What is the relationship between the force acting on an object and its acceleration, according to Newton's second law of motion?
What is the relationship between the force acting on an object and its acceleration, according to Newton's second law of motion?
- Force has no effect on acceleration.
- Force is inversely proportional to acceleration.
- Force and acceleration are unrelated.
- Force is directly proportional to acceleration. (correct)
According to Newton's third law of motion, when a force is exerted by object A on object B, what is the reaction?
According to Newton's third law of motion, when a force is exerted by object A on object B, what is the reaction?
- Object B exerts a force in the same direction on object A.
- Object B exerts a greater force on object A.
- Object B exerts no force on object A.
- Object B exerts an equal and opposite force on object A. (correct)
