kinematics Flashcards
Displacement definition
kinematics
shortest distance from a fixed point in a specified direction
Distance definition
kinematics
the length travelled by (object) between 2 points
Scalar Quantities
kinematics
- distance
- speed
Vector Quantities
kinematics
- displacement
- velocity
- acceleration
Speed definition
kinematics
distance travelled per unit time
Velocity definition
kinematics
change in displacement per unit time
Instantaneous vs Average
kinematics
instantaneous
rate of change in distance/displacement at that period
average
total distance/displacement / total time taken
Acceleration definition
kinematics
rate of change of velocity

Using of EOMs
kinematics
- only applicable when acceleration is constant
- only interested in the initial and final position of the object
Projectile Motion definition
kinematics
occurs when the path of the object in motion is a parabola
