mechanics

Question 1

suvat equations

Answer 1

1. s=ut+1/2at^2
2. s=vt-1/2at^2
3. v^2=u^2+2as
4. s=u+v/2 x t
5. v= u + at

Question 2

newton’s 2nd law

Answer 2

f=ma

Question 3

newtons 3rd law

Answer 3

every action has an equal and opposite reaction

Question 4

newton’s 1st law

Answer 4

an object will stay in motion or at rest unless an equal and opposite force acts on it

Question 5

equation used for horizontal projectiles

Answer 5

s=ut+1/2at^2

Question 6

equation used for vertical projectiles

Answer 6

for maximum height- v^2=u^2+2as

time taken-s=ut+1/2at^2
