what is a Scalar quantity
a quantity with magnitude but no direction
1 of 11
what is a vector quantity
a quantity with magnitude AND direction
2 of 11
how to calculate the horizontal component of a vector
Fh= Fcosθ (side that encloses θ is horizontal)
3 of 11
how to calculate the vertical component of a vector
Fv+ Fsinθ
4 of 11
what are the 4 equations motion with constant acceleration
1. v = u + at 2. s= (u+v)/2 x t. 3.s=ut + 1/2at^2. 4. v^2 = u^2 +2as
5 of 11
what is free fall
the motion of an object undergoing an acceleration of ''g'', where no other force acts except for gravity
6 of 11
what is the value of g
9.81, unless given different value
7 of 11
sign conventions for g (when replacing a with g in Suvat equations)
g always downwards so negative, t always positive, u and v can be positive or negative, s can be positive or negative
8 of 11
projectile motion
horizontal and vertical components of objects motion are completely independent
9 of 11
projectile motion continued
projectiles follow curved path because horizontal remains constant while vertical velocity is affected by acceleration due to gravity g
10 of 11
projectile motion cntd
resolve the velocity in projectile motion by using horizontal and vertical components
