### Understanding Unbalanced Forces

#### Key Concepts:

**Unbalanced Forces:**
- Unbalanced forces occur when two forces acting on an object are not equal in size, causing the object to move in the direction of the larger force.

**Applications:**
1. **Rocket Engines:**
- A rocket engine propels an object forward very quickly due to the large, unbalanced force it generates against the thrust.
- When a parachute is deployed, it provides a significant unbalanced force in the opposite direction, slowing the car down.

![Rocket Engine Example](image1)

2. **Motorbike Turning:**
- Leaning to one side while on a motorbike helps in turning corners.
- Turning the bike creates friction between the tires and the road, which changes the direction of the bike.

### Short Answer Questions:

1. **Scenario Analysis:**
- **Situation:** A driver and his passenger exit their car, which has run out of gas. Unsure of the nearest gas station, they push on opposite ends of the car with equal force.

- **Questions:**
1. *Sketching the situation*:
- Draw the car as a rectangle.
- Use arrows at both ends of the rectangle (one pointing left and one pointing right) to show the equal forces applied by the driver and passenger.

2. *Balance of Forces:*
- The forces on the car are balanced because the equal forces applied in opposite directions cancel each other out, resulting in no movement of the car.

2. **Floatplane Example:**
- **Scenario:** A floatplane lands on a harbor. As the float touches the water, the plane slows down.

- **Questions:**
1. *Balancing Forces:*
- The forces on the plane are unbalanced during landing as the water exerts resistance.

2. *Type of Force:*
- The water exerts a resistive force (drag) on the floatplane’s floats, causing it to slow down.

3. *Sketching the Landing:*
- Draw the floatplane with arrows indicating various forces:
- The direction of the plane's motion (forward) with one arrow.
- The drag force of the water (backward) with another arrow.
