kinematics

Question 1

what is distance?

Answer 1

distance is the actual or total length travelled by an object in motion it is also a scalar quantity

Question 2

what is displacement?

Answer 2

displacement is the direction moved in a specific direction.it is a vector quantity and is the straight-line distance between the starting position and the final position.

Question 3

what is a vector quantity?

Answer 3

a vector quantity has both magnitude and direction eg displacement velocity acceleration momentum force

Question 4

what is a scalar quantity?

Answer 4

scalar only has magnitude (cm, kg,) eg length area speed mass density temperature

Question 5

how do we find displacement?

Answer 5

displacement=final postion- initial position(start)

Question 6

tip!!!!!!!!!!!!!!!!!!!!!!!!

Answer 6

When writing displacement RMB to write displacement =10km EAST/WEST/NORTH/SOUTH
when the displacement is 0 don’t write east north south-west

Question 7

tip!!!!!!!!!!!!!!

Answer 7

distance travelled and displacement is TWO different things. distance travelled is the total distance that the person travelled but if the person just when back whr it start the displacement is 0

Question 8

tipXD

Answer 8

NORTH

WEST EAST

         SOUTH

Question 9

speed

Answer 9

speed=distance travelled/time taken

Question 10

average speed

Answer 10

average speed =total distance travelled/total time taken

Question 11

what is velocity

Answer 11

velocity is the distaance travelled per unit time in a specified direction and also be defined as the rate of change of displacement 60/h moving towards east.

Question 12

velocity formula

Answer 12

velocity=displacement/time taken

Question 13

acceleration (rate of change of velocity )

Answer 13

acceleration=change in velocity/time taken

a=v-u/t a=acceleration v-u= final position -start poisition t=time taken

Question 14

instantaneous speed

Answer 14

speed at a particular time

Question 15

instantaneous velocity

Answer 15

velocity at a particular time
