Speed and direction together are an object's velocity.
Speed and direction of travel are typically referred to as velocity. Velocity is a vector quantity that includes both the speed of an object and the direction in which it is moving.
Speed plus the direction of travel.
The speed of a moving object taken together with its direction of travel gives the velocity of an object. Velocity is a vector quantity that includes both the speed and direction of an object in motion.
Applying more force in the direction of travel will increase the acceleration and therefore speed. If more force is applyed opposite to the direction of travel, acceleration will decrease.
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
The speed of a moving object taken together with its direction of travel gives the velocity of the object. Velocity is a vector quantity that includes both speed and direction, so it describes how fast an object is moving and in what direction.
No such thing.Scalar quantities are values that have size but not direction such as mass or speed (as opposed to velocity which includes the direction of travel).
Waves.
No, most objects do not travel at a constant speed. Factors like forces acting on the object, changes in direction, and external influences can cause an object's speed to vary. Objects may speed up, slow down, or change direction as they move.
Simly stated, velocity is speed in a defined direction. If you travel 5mph north, the speed is the same as if you travel 5mph east, but the velocity is different.
