After breaking up, Jane slapped John with a force of 15 N. But John did not slap back because he knows that he exerted the same amount of force on Jane. What concept supported the idea of John?
Law of Inertia
Law of Acceleration
Law of Interaction
Law of Gravitation
Conservation of Energy
A body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This statement is known as
Law of Inertia
Law of Acceleration
Law of Interaction
Law of Gravitation
Conservation of Energy
Whenever one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts. This statement is known as
Law of Inertia
Law of Acceleration
Law of Interaction
Law of Gravitation
Conservation of Energy
The acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. This statement is known as
Law of Inertia
Law of Acceleration
Law of Interaction
Law of Gravitation
Conservation of Energy
1 Newton of force is equal to
1 kg m/s
1 kg m/s2
