When u kick a stone your foot exerts force on the stone and the stone exerts a force ? in size and ? in direction on your foot
equal, opposite
No
When you kick a stone, your foot exerts a force on the stone and the stone exerts a force back on your foot. The force exerted by your foot on the stone is known as the action force, while the force exerted by the stone on your foot is the reaction force.
To understand the size and direction of the forces involved, you can consider Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. This means that the force exerted by your foot on the stone is equal in size to the force exerted by the stone on your foot, but they act in opposite directions.
To calculate the force exerted, you can use Newton's Second Law of Motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, the force exerted will depend on the strength with which you kick the stone, as well as the mass of the stone.
It's important to note that the stone's force on your foot may not necessarily cause you to feel much impact, as the force can spread out and be absorbed by your body and the ground. However, if the stone is exceptionally heavy or you kick it with enough force, you may feel the impact and experience discomfort or injury.
