WHAT IS SPEED?
KNOW >
I know that speed is the distance covered by a moving object in a certain time.
APPLY >>
I can calculate the speed of an object by applying the equation:
speed = distance travelled ÷ time taken.
EXTEND >>>
I can extend my knowledge of speed and explain the difference between average speed and instantaneous speed. CONCEPT 2
DESCRIBING JOURNEYS WITH DISTANCE-TIME GRAPHS
KNOW >
I know how to interpret distance-time graphs and I can calculate the speed of an object using values from the distance-time graph.
APPLY >>
I can apply my knowledge of distance-time graphs to compare the speed of an object at different times of the journey and to also describe what acceleration is.
EXTEND >>>
I can extend my knowledge of distance-time graphs to explain complex journeys. CONCEPT 3
RELATIVE MOTION
KNOW >
I know how to describe relative motion.
APPLY >>
I can apply my knowledge of relative motion to calculate the relative speed between two moving objects. uyuyuyg
EXTEND >>>
I can extend my knowledge of relative motion to predict how objects may appear to move when viewed from different points of view.
