when you know both speed and direction of an objects motion you know the velocity of an object.
Why speed is considered as incomplete quantity to describe motion?
Because it doesn't have direction - Velocity is usually used to describe motion in physics because it has both speed and direction.
How do you describe an object's motion?

How does gravity keep objects in motion?
It doesn't. It will change an objects direction and/or speed but its inertia that keeps it moving.

Is velocity an objects speed and direction of motion?
Velocity is an objects speed in a given direction e.g. a runner having run round a circular track of 400m in circumference has 0 velocity.
Describe the law of conservation of momentum?
An object in motion tends to stay in motion at a constant speed and direction, unless some force acts upon it to change its speed and/or direction.
