- Newton’s Third Law of Motion states, “When one object exerts a force on a second object, the second one exerts a force on the first that is equal in magnitude and opposite in direction.”
- This law is sometimes called the “Law of Action and Reaction”.
- Even though the forces are equal in magnitude (strength) and opposite in direction, they do not cancel each other. This law addresses two objects, each with only one force exerted on it.
- Each object is exerting one force on the other object.
- Each object is experiencing only one force.
- The action and reaction forces are reciprocal (opposite) on an object.
- Examples may include:
- A swimmer swimming forward:
- The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward.
- A ball is thrown against a wall:
- The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
- A person is diving off a raft:
- The person puts a force on the raft (action force) pushing it, and the raft puts a force on the diver (reaction force) pushing them in the opposite direction.
- A person pushes against a wall (action force), and the wall exerts an equal and opposite force against the person (reaction force).
- The Space Shuttle engines push out hot gases (action force), and the hot gases put a force on the shuttle engines (reaction force) so the shuttle lifts (there is no sling shot doing it!)
A single brain is not always capable of making key decisions on its own. To come up with an efficient solution, an individual requires the help and advice of others. A team is established when individuals get together on a common platform with the common goal of completing a task. To guarantee optimum compatibility, team members should ideally come from similar backgrounds and have a single aim. To provide their best, the team members must complement each other and function as a single unit in tight cooperation. "There is no I in Team Work," as the saying goes, and each member must put the needs of his team first. Personal interests must take a second seat. Any team's performance is directly proportionate to the relationship between its members and their combined efforts. What is the definition of teamwork? Teamwork is defined as the sum of each team member's efforts toward the fulfilment of the team's goal. In other words, any team's backbone is its ability t
