Kinematics:
Mechanics: Branch of physical science that deals with energy and forces and their e ect on bodies
Vector: Physical quantity that has both magnitude and direction. eg. Force
Scalar: Physical quantity that has only magnitude. eg. Direction
Resultant vector: Single vector that has same e ect as original vectors acting together
Distance: Length of path travelled (scalar quantity)
Displacement: Change in position (vector quantity)
Speed: Rate of change of distance (scalar quantity)
Velocity: Rate of change of position / Rate of displacement (vector quantity)
Acceleration: Rate of change of velocity
Vertical projectile motion:
