physics

Question 1

distance

Answer 1

distance traveled by object

Question 2

displacement

Answer 2

shortest path in straight line from point A to point B

Question 3

magnitude

Answer 3

numerical value

Question 4

scalar

Answer 4

only has magnitude(numerical value) eg: speed mass volume time

Question 5

vector

Answer 5

has both magnitude and direction eg: velocity weight friction

Question 6

unit of distance

Answer 6

metres

Question 7

unit of displacement

Answer 7

metres

Question 8

speed

Answer 8

rate at which an object covers distance, d/t

Question 9

unit of speed

Answer 9

metres/second

Question 10

velocity

Answer 10

similar to speed but with an added component of direction
displacement/time

Question 11

unit of velocity

Answer 11

displacement/time
meters/second

Question 12

newtons first law

Answer 12

Every object moves in a straight line unless acted upon by a force. an object at rest stays at rest

Question 13

newtons second law

Answer 13

the acceleration of an object depends on the mass and the amt of force applied

Question 14

newtons third law

Answer 14

For every action, there is an equal and opposite reaction.

Question 15

2nd law formula

Answer 15

F=ma
F- net force(newtons)
m- mass(kg)
a- acceleration(m/s^2)
