CIE IGCSE Physics equations (2023 onwards)

What is the equation to calculate speed?

• speed = distance/time
• speed = time/distance
• speed = time x distance 
• speed = speed/time 

The equation for finding average acceleration is

• (final velocity - initial velocity) ÷ time

• (initial velocity - final velocity) ÷ time

• initial velocity + final velocity + time

• initial velocity + final velocity - time

The equation for finding acceleration is

•  $a=\frac{\Delta v}{t}$  

•  $a=\frac{v}{t}$  

•  $a=\frac{\Delta v}{T}$   

•  $a\ =\ v\times t$  

What does  $\Delta$  mean in an equation

• change in

• increase in

• decrease in

• constant value
