movements in two dimensions

• vectors are kind of like ordinary numbers-which are also known as scalars- because thy have a magnitude, which tells you how big they are and what direction they are going.

• separate the vector by components, one y-axis component and one x-axis component

• How do you know when the ball will hit the ground?

• by ignoring the horizontal component and using the s=vt formula

• in harder questions find the starting velocity of each component
