Question a
State Newton's third law of motion.
Worked Solution & Example Answer:State Newton's third law of motion. - Leaving Cert Physics - Question a - 2006
Step 1
Newton's third law of motion states that action and reaction are equal
Answer
In the context of Newton's third law, when body A exerts a force on body B, body B exerts a force back on body A. These forces are equal in magnitude but opposite in direction. This principle highlights that forces always come in pairs; thus for every action, there is an equal and opposite reaction.
Step 2
(and) opposite
Answer
To elaborate, the force that body B exerts on body A is not only equal in strength but also acts in the opposite direction to the force applied by body A on body B. This ensures that the net force acting on a system remains balanced unless an external force is applied.
