Simple machines are basic mechanical devices that use a single applied force to perform a specific task, such as lifting an object or applying a force to an object. There are six types of simple machines: lever, pulley, inclined plane, wedge, screw, and wheel and axle. These machines can be combined to create more complex machines, such as a car or a computer.

Activity 1.1 in a simple machines unit might involve practicing problems to test students' understanding of these devices. An answer key for this activity might include solutions to the following types of problems:

  1. Identifying the type of simple machine: For example, a student might be presented with a diagram of a hammer and asked to identify which simple machine it represents. The answer key would indicate that a hammer is a type of wedge.

  2. Calculating mechanical advantage: Simple machines can increase the force applied to an object, known as mechanical advantage. For example, a student might be asked to calculate the mechanical advantage of a lever with a fulcrum located 3 meters from a load and a force applied 6 meters from the fulcrum. The answer key would indicate that the mechanical advantage is 2, as the load is moved twice the distance of the force.

  3. Determining the efficiency of a simple machine: The efficiency of a simple machine is the ratio of the output force to the input force. A student might be asked to calculate the efficiency of a pulley system with a mechanical advantage of 4 and an input force of 100 Newtons. The answer key would indicate that the efficiency is 25%, as the output force is 400 Newtons (4 x 100 Newtons) and the input force is 100 Newtons.

In conclusion, activity 1.1 in a simple machines unit might involve practicing problems to test students' understanding of these basic mechanical devices. An answer key for this activity could include solutions to problems involving identification of simple machines, calculation of mechanical advantage, and determination of efficiency.
