Physics Equations

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
