Which of the following is an accurate statement about Newton's second law of motion?
- The net force acting on an object is directly proportional to its acceleration and inversely proportional to its mass
- The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (correct)
- The acceleration of an object is directly proportional to its mass and inversely proportional to the net force acting on it
- The net force acting on an object is directly proportional to its mass and inversely proportional to its acceleration
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that:
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that:
- The force exerted by object A on object B is greater than the force exerted by object B on object A
- The force exerted by object A on object B is in the same direction as the force exerted by object B on object A
- The force exerted by object A on object B is equal and opposite to the force exerted by object B on object A (correct)
- The force exerted by object A on object B is unrelated to the force exerted by object B on object A
