forces and motion

scalars are quantities that only provide information about size, for example, speed, distance, time, mass

Vectors are quantities that provide information

about size and direction, for example, displacement, acceleration, weight, velocity

distance= length from one point to another unit-m

speed=distance travelled in 1 second unit-m/s

s=d/t

ave speed = u+v/2

RoCoS = v-u/t

displacement=length between 2 points in certain direction
