Vector arrow length shows
Vector arrow length shows
Magnitude of the vector
Vector arrow direction shows
Vector arrow direction shows
Direction of the vector
Can vectors be negative?
Can vectors be negative?
Yes, depending on direction
Speed vs velocity
Speed vs velocity
Speed: magnitude only. Velocity: magnitude + direction
Why velocity changes on a roundabout
Why velocity changes on a roundabout
Direction constantly changes
Constant speed, changing direction means
Constant speed, changing direction means
Acceleration
Scalars: positive or negative?
Scalars: positive or negative?
Generally non-negative
