Learning Objectives
Candidates should be able to:
(a) define and use displacement, speed, velocity and acceleration
(b) use graphical methods to represent distance, displacement, speed, velocity and acceleration
(c) identify and use the physical quantities from the gradients of displacementtime graphs and areas under and gradients of velocitytime graphs, including cases of nonuniform acceleration
(d) derive, from the definitions of velocity and acceleration, equations which represent uniformly accelerated motion in a straight line
(e) solve problems using equations which represent uniformly accelerated motion in a straight line, including the motion of bodies falling in a uniform gravitational field without air resistance
(f) describe qualitatively the motion of bodies falling in a uniform gravitational field with air resistance
(g) describe and explain motion due to a uniform velocity in one direction and a uniform acceleration in a perpendicular direction.

Key inquiry question:
How can we describe the motion of objects moving in a straight line?
1. Speed, velocity and acceleration
• Physical quantities can be scalar (e.g. distance, speed) or vector (e.g. displacement, velocity, acceleration) quantities. Scalar quantities can be added algebraically. Vector quantities can be added using graphical methods (parallelogram method or ‘headtotail’ method).
• Average speed of a body is given by total distance travelled / total time taken (v = d/t). Instantaneous speed is the speed at any instant.
• Acceleration of a body is defined as its change in velocity / time taken (a = (v  u)/t). The direction of acceleration is the direction of the change in velocity.
• Acceleration is: zero when velocity is constant (i.e. no change in velocity); positive (object is accelerating) when velocity is increasing; negative (object is decelerating) when velocity is decreasing
2. Graphical analysis of motion
• Displacementtime and velocitytime graphs of a body allow us to deduce when the body is: at rest; moving with uniform velocity and acceleration; moving with nonuniform velocity and acceleration.
• Gradient of a displacementtime graph gives the velocity of the moving object; Gradient of a velocitytime graph gives the acceleration of the moving object; Area under a velocitytime graph gives the displacement travelled by a body.
Students’ prior knowledge of Kinematics
Primary level:
Students will not have been introduced to the concepts to describe motion. They would have knowledge of the effects of a force to stop or move an object; change its speed (move faster or slower) or direction of motion.
Lower secondary level:
Students learn that speed:
• is a measure of how fast an object is moving;
• depends on the distance (length) travelled and the time taken (unit: m/s).
Objects usually do not move at the same speed, hence, it is more useful to measure its average speed which is defined as total distance travelled / total time taken. Speed at any instant is the average speed over an extremely short time interval.
Students’ common misconceptions and learning difficulties in Kinematics
Displacement, velocity and acceleration:
Students’ concepts of displacement, velocity, and acceleration are not well differentiated. They often think that: same position means same velocity for two objects; same velocity means same acceleration for two objects; larger (or smaller) velocity means larger (or smaller) acceleration; zero velocity means zero acceleration; and acceleration and velocity are always in the same direction. Displacementtime and velocitytime graphs: Students often view the position and velocity graphs as the actual path of the object, rather than a graphical representation of an object’s motion

Technology:
mystery could take the form an describe it all equation, called model.
Give the challenge to solve the mystery of a predictive equation that can be use to tell the future, more precisely the movement of a car, in a physics lesson.
Through the model selected by the students, it gives an indication of the students prior knowledge about what they know now, so that the teacher can understand the gaps of understanding for personalised mentoring http://iwant2study.org/ospsg/index.php/interactiveresources/physics/02newtonianmechanics/01kinematics/38kinematics1d
