1. Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs, with one body exerting a force on another, and vice versa.

  2. A table tennis ball hitting a player doesn't hurt as much as a cricket ball hitting a spectator because the table tennis ball has significantly less mass and velocity, resulting in lower kinetic energy and impact force compared to the cricket ball.

  3. When an unbalanced external force acts on an object, its velocity changes, meaning the object accelerates in the direction of the force, altering its speed and/or direction of motion.

  4. A small mass like a bullet has significant destructive power when fired from a gun due to its high velocity, which results in a large amount of kinetic energy. This energy is transferred upon impact, causing substantial damage.

  5. A moving truck, even at low speeds, poses greater danger than when stationary due to its large mass and momentum. The kinetic energy it carries can cause significant damage upon collision, whereas a stationary truck exerts no impact force and thus poses minimal immediate risk.
