1. define the following vocabulary terms: a. speed: b. direction: c. velocity: d. vector: e. position: f. acceleration: g. force: h. newton:

a) Speed: It is the ratio of distance covered and time interval to cover that distance

it is given as

b) Direction: it will define for vector quantities and shows the required direction for it

c) Velocity : It is rate of change in position or it is ratio of displacement and time

d) Vector : it is a type of physical quantity which will be defined by magnitude and direction both

e) Position : it is defined as the distance with respect to a given reference or origin

f) Acceleration : it is defined by rate of change in velocity.

g) Force = it is push or pull on an object which will create acceleration to the object

F = ma

it is product of mass and acceleration

h) Newton : it is SI unit of force or we measure force in this unit
