The difference between speed and velocity is...

• Speed has direction.

• Velocity has direction.

• They are the same thing.

This occurs when an object speeds up, slows down, or changes direction.

• Speed

• Velocity

• Acceleration

Acceleration =

• $\frac{\left(FinalVelocity\ -\ InitialVelocity\right)}{Time}$

• $\left(FinalVelocity\ -\ InitialVelocity\right)$

• $\frac{Time}{\left(FinalVelocity\ -\ Initial\ Velocity\right)}$

• $\frac{\left(InitialVelocity\ -\ FinalVelocity\right)}{Time}$
