### 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. ![Motorbike Turning](image2)---### 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.This content provides an understanding of un

Short Answer Questions 1. A driver and his passenger get out of their car, that has run out of gas on the street. They cannot agree on which gas station is closer, so they begin pushing with equal force on opposite ends of the car. a. Make a sketch of this car-pushing situation using arrows to represent the forces on the car. b. Use your sketch to explain whether the forces on the car are balanced or unbalanced.
