Lecture 5: Rearranging Formula

Question 1

What does SUVAT stand for

Answer 1

S is displacement
U is initial velocity
V is final velocity
a is acceleration
t is time

Question 2

In a Velocity/time graph what does the area under the graph mean ? How do you calculate this?

Answer 2

Displacement
Mean velocity x time
Mean is the 1/2 way between v and u
Therefore
S = 1/2 (u + v ) t

Question 3

What does the gradient represent in a velocity/time graph?

Answer 3

The acceleration

Change in velocity/ time

Question 4

What the second SUVAT equation need to learn?

Answer 4

V= u + at

Question 5

What’s the third SUVAT equation need to learn ?

Answer 5

S = ut + 1/2at^2

Question 6

What’s the fourth SUVAT equation?

Answer 6

V^2 = u^2 + 2as
