C. Velocity - speed in a particular direction

Velocity & Direction - St. Mary's H.S.

We can say that Joe has 3 velocities

V = 6.5 m/s N.E.

V = 5 m N/2 seconds =

2.5 m/s North

V = 12 m East/2seconds

= 6 m/s East

1. Velocity is always written with direction

Examples

• 5m/s east

• +5m/s

• 100 m/s downward

• -100 m/s

2. Equation: V = ∆d/∆t

For straight line motion:
v = distance/time and direction

Acceleration
