Physics
You have studied about different types of forces in this chapter. Observe the given picture.
What are the types of forces displayed in the picture? Specify the exact location of the force exerted and the type of forces involved. Tabulate your observation. Discuss it in class.
Answer
| Location of Force | Type of Force | Explanation |
|---|---|---|
| Hands of players pulling the rope | Muscular force (contact force) | Players use their muscles to pull the rope. |
| Rope being pulled tightly | Tension force (contact force) | The rope is stretched due to equal and opposite pulls by both teams. |
| Feet of players against the ground | Frictional force (contact force) | Friction between the shoes and ground prevents slipping and helps players push backward. |
| Players standing on Earth | Gravitational force (non-contact force) | Earth pulls players downward, keeping them on the ground. |
| Ground supporting the players | Normal force (contact force) | The ground pushes upward on players, balancing their weight. |
