Want this question answered?
The sheep's momentum vector has a magnitude of 250 kilogram-meters per second,and a direction of east.
Momentum = (mass) x (velocity) = (1,100) x (30) = 33,000kg-m/sec due east
Speed is just a magnitude (25 m/s), which is known as a scalar value. Velocity, however, is a magnitude with a direction (25 m/s East), which is known as a vector value.
Velocity is a vector that has both magnitude and direction. Magnitude tells you how fast it is moving (speed) and direction tells you which way it is moving. For example car traveling at 60 mph due East has a sped of 60 mph and direction East. The combination of speed and direction is velocity.
Remember that velocity is a vector quantity which means it needs two criteria to be defined; a magnitude, and a direction. When we discuss the magnitude of velocity, what we are talking about is the speed (30m/s, 45mph, etc). Those examples are examples of speed; it is only when we add a direction that it becomes 'velocity'. So, the difference is: "25m/s" is a speed, but "25m/s east" is a velocity. Speed (the magnitude of velocity) is calculated by taking the total displacement divided by the total time. Speed=(distance travelled)/(time it takes). Hope this helps

In physics, velocity is the rate of change of position. It is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is speed. For example, "5 meters per second" is a scalar and not a vector, whereas "5 meters per second east" is a vector. So in short the difference between velocity and speed is that speed is determined by magnitude whereas both magnitude and direction determine velocity.
Speed is how fast the movement is. It contains only a magnitude. Velocity is speed plus a direction, and is known as a vector.Speed: 40mphVelcoity:40mph/east
Velocity is a vector, meaning it has a direction, like east, north, up. Speed isa magnitude without direction, 60 miles per hour is a speed; 60 miles per hour north is a velocity. When a care is going 60 mph in a circle the speed is constant but the velocity changes as the direction changes. The magnitude of the velocity is the same but the direction changes thus the velocity changes. Velocity changes if either the speed/magnitude or the direction change.

Well, picture this: A canoe moving east through the water at 3 miles per hour hits the pier, and bounces off of it. About an hour later, a battleship moving east through the water at 3 miles per hour hits the pier, keeps right on going, and demolishes the entire pier.What's the difference ? Both craft had the same velocity ... 3 miles per hour eastward. But each one had different momentum. The difference between velocity and momentum is that momentum also depends on the mass of the object, as well as its velocity.Momentum of an object is (mass) multiplied by (velocity).
The change of velocity is 75 km/hr west.
