PHYSIC S

Think back to GCSE 1.Write down the definition of velocity Speed in a given direction 2.Write down the calculation for velocity But that is how you calculate speed, which you just said is different to velocity

Distance (x) Displacement (s)

Velocity (v) = Displacement (s) Time (t) Speed (v) = Distance (x) Time (t) Scalar Vector Magnitude Direction  Magnitude

s [m] t [s] Gradient = dy/dx = s/t = v

s [m] t [s] v [m/s] t [s]

+ve direction Consider the motion of a projectile (negligible air resistance)

v [m/s] t [s] If the acceleration due to gravity is -9.8 ms -2
