Physics

Module 1

Kinematics

the study of motion without considering its causes

Position

the location of an object at any particular time

Reference Frame

the position of an object as it relates to stationary objects

Displacement

the net change in position of an object (written as Δd)

Magnitude

the size or amount, of distance traveled

Scalar

a quantity, that has magnitude and sometimes a sign but no direction

Vector

a quantity, that has both magnitude and direction

Distance

an object moves is the length of the path between its initial and final position

Speed

the rate at which an object changes its location

Average Speed

the distance traveled divided by the time during which the motion occurs

Instantaneous Speed

the speed of a specific instant in time

Velocity

the speed and direction of an object

Average Velocity

the displacement divided by the time over which displacement occurs (Δd/ /Δt)

Instantaneous Velocity

the velocity at a specific instant in time

Independent Variable

the horizontal axis

Dependent Variable

the vertical axis

Tangent

a straight line

Acceleration

the rate of change of velocity
