Speed is a scalar magnitude (it only tells you how much). Velocity is composed of the object's speed and the direction in which it's moving. This corresponds to the definition of a vector.
Using "miles" and "hours" as an example:
- "30 miles per hour (mph) " is a speed
- "30 miles per hour (mph) north" is a velocity
- "30 mph north" and "30 mph east" are different velocities with the same speed.
- "30 mph north" and "35 mph north" are different velocities/speeds with the same direction.
- If you add "30 mph" plus "30 mph", you get 60 mph ... maybe.
- If you add "30 mph north" plus "30 mph south", you get standing still.
- If you add "30 mph north" plus "30 mph east", you get 42.426 mph northeast, using vector calculations.
Therefore, when a vehicle travels on a winding road maintaining a speed of 30 mph, its speed remains the same but its velocity is changing with each turn.
What else can I help you with?
What is the difference an objects speed and an objects velocity?
Speed only tells how fast something is going, while velocity tells speed and direction.
How do you measure an objects speed and direction?
Velocity
What is the difference of an objects speed and an objects volocity?
when you know both speed and direction of an objects motion you know the velocity of an object.
Which term can be described both the speed and the direction of an objects motion?
VELOCITY
Consists of an objects speed and direction?
angular velocity
Two objects traveling at the same speed have different velocities if they...?
...travel in different directions relative to a reference point. Velocity is a vector quantity that includes both speed and direction, so even if objects are moving at the same speed, their velocities can differ if they are moving in different directions.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
What includes the speed of the objects and the direction of its motion?
Speed and direction is called velocity.
The measure of an objects speed and direction is the objects?
The measure of an object's speed and direction is the object's velocity. Velocity is a vector quantity that includes both the speed (magnitude) and the direction of motion of an object.
What forces can affect an objects velocity but not the speed?
Centripetal forces can.
What term can best describe both speed and direction of an objects motion?
That is called "velocity".
What is it called When an objects speed is not changing?
Terminal velocity if it has reached its top speed. Or obviously constant speed.
