Question 1

S explain the left-hand side
V
A

Answer 1

displacement
velocity
time
the slope of the displacement = velocity
the slope of velocity = acceleration

Question 2

S explain the right hand side
V
A

Answer 2

Displacement
velocity
time
the area under acceleration = velocity
the area under velocity = displacement
