Kinematics
The science of describing the motion of objects using words, equations, diagrams, graphs and numbers
Vector quantity
-has direction and magnitude
Scalar quantity
has magnitude. no direction
distance
How much ground is covered during an object's motion
displacement
How much ground an object has covered in a specified direction during its motion
speed
-Scalar Quantity<br/><br/>- The rate of change of distance moved with time
Instantaneous Speed
the speed at any given instant in time
Average speed
distance/time
velocity
-vector quantity<br/><br/>- rate of change of distance moved with time in a specified direction ( rate of change of direction)
Uniform velocity
rate of change of displacement is constant
Acceleration
Rate of change of velocity with time
Uniform acceleration
rate of change of velocity with time is constant
