Chap 2 - 4

Question 1

Acceleration formula

Answer 1

a=(v-u) / t
acceleration(m/s²)=
(end speed-initial speed) /time

Question 2

Distance?

Answer 2

Area under Speed-Time graph
D=Speed*time

Question 3

Pressure formula

Answer 3

P=F/A
Pressure(Pa)=Force(N) / Area(m²)

Question 4

Force formula

Answer 4

F=ma
Force(N)=mass(kg) * acceleration(m/s²)

Question 5

When speed is constant, what is resultant force

Answer 5

resultant force = 0

Question 6

What is Newton’s Third Law?

Answer 6

Every action has its equal opposite reaction

Question 7

Resultant Force Fomula

Answer 7

Fr = force in same direction - force in opposite direction
