Question
Which law applies here?
- Newton’s first law of motion
- Newton’s second law of motion
- Newton’s third law of motion
- More than 2 laws of motion
Hint:
Newtons third law
The correct answer is: Newton’s third law of motion
Newton’s third law of motion.
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself
When a person is walking on the ground, he is pushing the ground backward with some force and as per newton's third law, the ground exerts an equal and opposite force on the person. This reactive force enables the person to move forward
