,VECTORS AND SCALARS
KINEMATICS
VECTOR: A PHYSICAL QUANTITY THAT HAS BOTH MAGNITUDE AND DIRECTION EG: DISPLACEMENT OR VELOCITY
SCALAR: A PHYSICAL QUANTITY THAT HAS MAGNITUDE ONLY EG: DISTANCE OR SPEED
RESULTANT VECTOR: THE SINGLE VECTOR WHICH HAS THE SAME EFFECT AS THE ORIGINAL VECTORS ACTING TOGETHER.

THE RED ARROW IS FORCE ONE.
THE GREEN ARROW IS FORCE TWO.
THE BLACK ARROW IS THE RESULTANT VECTOR.

YOU CAN DETERMINE THE PERPENDICULAR COMPONENTS OF ANY VECTOR .USING A RIGHT ANGLED TRIANGLE, AND THE SIN, COS, AND TAN. RULES
DISTANCE: THE LENGTH OF PATH TRAVELLED FOR EXAMPLE:
FMX
DISPLACEMENT: A CHANGE IN POSITION
SPEED: THE RATE OF CHANGE OF DISTANCE
VELOCITY: THE RATE OF CHANGE OF POSITION
ACCELERATION: THE RATE OF CHANGE OF VELOCITY sine

KNOW THE DIFFERENCE BETWEEN AVERAGE VELOCITY AND INSTANTANEOUS VELOCITY 10

VERTICAL PROJECTILE MOTION IN ONE DIMENSION
PROJECTILES FALL FREELY WITH GRAVITATIONAL ACCELERATION g 9.8ms 2

*NOTE: PROJECTILES TAKE THE SAME AMOUNT OF TIME TO REACH THEIR GREATEST HEIGHT FROM THE POINT OF UPWARD LAUNCH AS THE TIME
THEY TAKE TO FALL BACK TO THE POINT OF LAUNCH.
EQUATIONS OF MOTION
GRAPHS OF MOTIO
MUST BE ABLE TO DRAW THE FOLLOWING GRAPHS:
• POSITION VS TIME
• VELOCITY VS TIME
• ACCELERATION VS TIME
MUST BE ABLE TO INTERPRET GRAPHS OF MOTION:
• DETERMINE THE VELOCITY OF AN OBJECT FROM THE GRADIENT OF A POSITION VS TIME GRAPH.
• DETERMINE THE ACCELERATION OF AN OBJECT FROM THE GRADIENT OF A VELOCITY VS TIME GRAPH.
• DETERMINE THE DISPLACEMENT OF AN OBJECT BY FINDING THE AREA UNDER A VELOCITY VS TIME GRAPH For tutoring

NEWTON'S LAWS
WEIGHT : THE GRAVITATIONAL FORCE THE EARTH EXERTS ON ANY OBJECT ON OR NEAR ITS SURFACE
HOW TO CALCULATE WEIGHT

NORMAL FORCE : THE PERPENDICULAR FORCE EXERTED BY A SURFACE ON AN OBJECT IN CONTACT WITH IT
FRICTIONAL FORCE DUE TO A SURFACE : THE FORCE THAT OPPOSES THE MOTION OF AN OBJECT AND ACTS PARALLEL TO THE SURFACE
WITH WHICH THE OBJECT IS IN CONTACT

COEFFICIENT OF STATIC
MAXIMUM STATIC FRICTION FRICTION
