distance covered by the object per unit time is the speed of the object.
That is called speed, as opposed to velocity, which is a combination of speed and direction.
K
The net force is in the same direction as the acceleration of an object.
Yes. The simplest such case is when the object is moving along a circle.
Speed is how fast something is going when the direction in which it is travelling is unimportant. Velocity is a measurement of the rate at which an object is changing its position. As such, in order to measure it, one must define both the speed at which an object is moving, and also the direction of movement.
No force is required to keep an object moving at constant speed in a straight line. Force is required only to change its speed or direction.
velocity
The net force is in the same direction as the acceleration of an object.
Moving in the positive direction at an increasing speed. (Accelerating positively)
The drag envelope is the space around a moving object that causes friction, pushing in the opposite direction of where the object is going.
Yes. The simplest such case is when the object is moving along a circle.
Once an object is moving in space, no fuel is needed tokeep it going, only to change its speed or direction.
wichever direction you start walking in is the direction you will be going.................................................................idiot

How fast it is going in a certain direction

The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
