Introduction (10 - 12 minutes)

1. Recap of Previous Knowledge: The teacher starts the class by reminding students of the basic concepts of motion they have already learned, such as the definitions of speed, velocity, and acceleration. The teacher will also review the equations of motion for uniformly accelerated motion that they have covered in the previous lessons. This step is crucial to ensure that students have the necessary background knowledge to understand the topic of uniformly varied motion.

2. Problem Situations: The teacher presents two problem situations to kick-start the students' thinking. One problem could be about a car accelerating from rest to a certain speed in a given time, and the other about a ball thrown up in the air and then falling back down. The teacher asks the students to think about how the motion changes in each situation and what factors might be causing the changes.

3. Real-World Context: The teacher then contextualizes the importance of the subject by explaining how uniformly varied motion is a fundamental concept in many real-world applications. For instance, it is essential in understanding the motion of vehicles, the behavior of objects in freefall, and even the physics of sports such as tennis or soccer.

4. Attention-Grabbing Introduction: To pique the students' interest, the teacher shares two intriguing stories related to uniformly varied motion.

   • The first story could be about the Paralympic athletes who use specially designed wheelchairs that allow them to accelerate and decelerate quickly, highlighting the importance of understanding uniformly varied motion in designing such equipment.
   • The second story could be about the Apollo missions and how the astronauts had to carefully plan their take-offs and landings, considering the uniformly varied motion of the spacecraft due to the gravitational pull of the moon.

These stories not only make the topic more engaging but also help students to see the practical applications of uniformly varied motion.

2. Introduction of the Five Key Variables: The teacher introduces the five key variables of uniformly varied motion: initial velocity (u), final velocity (v), acceleration (a), time (t), and displacement (s).

   • Initial velocity (u): The teacher defines initial velocity as the speed and direction of the object at the start of the motion.

   • Final velocity (v): The teacher defines final velocity as the speed and direction of the object at the end of the motion.

   • Acceleration (a): The teacher explains that acceleration is the rate at which the velocity of an object changes. It could either be an increase or decrease in speed, or a change in direction.

   • Displacement (s): The teacher defines displacement as the change in position of the object in a particular direction.

3. Equations of Motion for Uniformly Varied Motion: The teacher explains the fundamental equations of motion that connect these variables:

   • v = u + at (Equation 1)
