Answer:
1).Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
2).The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance. It's a scalar quantity which means it is defined only by magnitude.
Answer:
speed: speed is the distance traveled by an object in unit time.
: Speed, being a scalar quantity, is the rate at which an object covers distance.
velocity: velocity is the speed of an object moving in an definite direction.
: velocity is a vector quantity; it is direction-aware.
