This was the essential question on a homework assignment.
Speed tells how fast an object is moving but it does not tell the direction.
Velocity tells how fast an object is moving and it also tells the direction.
When velocity is positive, the object is moving up.
When velocity is negative, the object is moving down.
What else can I help you with?
What is vector and resultant velocity?
A vector is used to represent direction and magnitude of speed. Velocity is the speed of an object and a specification of its direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. Therefore a vector can be used to represent a velocity. The term "resultant velocity" implies a change in velocity which can be determined using vector analysis.
In the acceleration equation what do v1 and v2 represent?
v1 = initial velocity v2 = final velocity
Can velocity be 0 but speed not 0?
Yes, velocity can be 0 while speed is not 0. Velocity is a vector quantity that includes both speed and direction, so if an object is moving in a straight line and comes to a stop, its velocity is 0 but its speed is not 0. Speed, on the other hand, is a scalar quantity that only considers the magnitude of the motion, regardless of direction.
When mass is decreased?
An object travelling at a velocity close to the speed of light had a higher mass than when at rest.
When ever an object is standing still which value is always zero?
Its speed, velocity, and acceleration are all zero.
How can you use integers to reprsent the speed and velocity of an object?
You can sometime use integers but often speed or velocity can also be irrational.

How can an arrow be used to represent and explain velocity?
An arrow can be used to represent and explain velocity by its length and direction. The length of the arrow indicates the speed of the object, while the direction of the arrow shows the object's movement. A longer arrow represents a faster speed, and the arrow pointing in a specific direction indicates the object's velocity in that direction.
The speed of an object and the direction of its motion?
the object's 'velocity'
What does a constant negative velocity graph represent in terms of an object's motion?
A constant negative velocity graph represents that the object is moving in the negative direction at a steady speed.
What describes the direction and speed of an object?
Velocity describes the speed and direction of an object.velocityvelocity
What is the speed of an object plus its direction?
The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.
What is the specific direction of a speed of an object?
The specific direction of an object's speed is known as velocity. Velocity includes both the speed of the object and the direction in which it is moving.
What measures speed and direction an object travels?
Velocity measures both speed and direction that an object travels. The magnitude of velocity represents the speed of the object, while the direction of velocity indicates the direction in which the object is moving.
What is the difference between an object's speed and a object's velocity?
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
What includes a moving object's direction and speed?
The velocity of a moving object includes its direction and speed. Velocity is a vector quantity that describes both the object's speed (magnitude of velocity) and its direction of motion.
What is shared between speed and velocity?
Both speed and velocity represent how fast an object is moving. However, velocity also includes the direction of movement, while speed is a scalar quantity that only indicates the magnitude of the movement.
