• The pupil explains uniform circular motion.
• The pupil understands the tangential direction.
• The pupil illustrates constant acceleration and acceleration due to gravity.
• The pupil identifies the relationship between relation between different terms.
• The pupil explains the relation between the slope and acceleration.

Asking questions and making hypothesis :

• The pupil asks for the applications of scalars and vectors.
• The pupil imagines rest and motion of Earth w.r.t other planets.
• The pupil asks for the difference of distance and displacement.
• The pupil asks for the zero displacement around the circle.
• The pupil imagines the rotator motion for planets .
• The pupil asks for the difference of instantaneous speed and average speed.
• The pupil asks for the decrease and increase of speed for vertically thrown and freely falling bodies.

Experiments and Field investigation:

• The pupil proves the relation between distance and displacement.
• The pupil proves the variation of speed and direction of motion.
• The pupil experiments and proves the direction of speed is tangential for a body in circular motion.
• The pupil find the acceleration and velocity of an object moving on an inclined plane.
• The pupil performs experiments with reasonable speed and neatness.

Collecting information and project work:

• The pupil collects the information about relativity of rest and motion.
• The pupil do the project of examples of scalar and vector quantities.
• The pupil collects the paper cutting about rest and motion.
• The pupil collects information about the objects, which are in uniform and non-uniform motion.
• The pupil collects information about the objects in different types of motions.

Drawing and Model making :

• The pupil draws the graph between distance and time.
• The pupil draws the tables to record observations of an experiment.
• The pupil draws the tangential direction of velocity to a body in circular motion at different points.

Appreciation and Aesthetic values:

• The pupil appreciates the importance of scalars and vectors in physics.
• The pupil appreciates the applicability of rest and motion to Earth practically for higher concepts.
• The pupil appreciates the relation between the concept of motion and our daily life.

Teaching notes:

• There must be a reference point to describe the position of the given body.
• Distance ≥ Displacement.
• Distance is a scalar quantity and Displacement is a vector quantity.
• The physical quantities which are described by only magnitude are called scalar quantities.
• The physical quantities which are described by both magnitude and direction are called as vector.
• Average velocity =  (Total dispalcement)/(Total time.)
• Instantaneous velocity is defined as the velocity at that particular time (second).
• When the velocity of a body decreases with time, then acceleration is called retardation or negative accelearation.
• The acceleration of a freely falling and vertically projected bodies is called acceleration due to gravity.
• The value of acceleration  due to gravity changes w.r.t height, depth , at equator and at poles.
• The standard value of acceleration due to gravity on Earth is 9.8 m/s2.
