18001022727Both speed and velocity provide a method of measuring an object's change in location relative to time. In reality, an object's speed and velocity are the same in a straightline motion (since distance and displacement will be the same). Speed and velocity are both measured in meters per second (m/s) as their SI units. The symbol ms 1 represents both speed and velocity. The magnitude of a moving body's speed and velocity are identical only if the body moves in a single straight line. Speed and velocity have their dimensional.
formula as [M^{0}LT^{1}].
Speed is the pace at which an item moves along a route in time. For example, 50 km/hr (31 mph) shows the speed at which a car travels down a road. We define the rate of change of distance as speed (how much distance (m) has been traveled in a time(s)). We determine speed by the rate at which the body travels. Speed is a scalar quantity since it only has magnitude. The formula for speed is:
Speed (or rate, r) is a scalar quantity that can be represented by the equation r = d/t. A vehicle travelling at 45 miles per hour is an example of speed. Someone cleaning a room in 10 minutes is an example of quickness. A jaguar's speed is an example of speed. When an object's speed is constant (it does not increase or decrease), we say it is travelling at a constant speed. The speedometer on a vehicle displays the instantaneous speed.
Velocity is the rate and direction of movement. For example, 50 km/hr west describes the velocity with which it travels. We define the rate of change of displacement as velocity ( change of distance in a particular direction with respect to time).
The velocity of an item determines its speed and the direction it moves in. Velocity is a vector quantity because it has both magnitude and direction. The formula for velocity is:
We define the displacement of a body in a particular time interval as velocity. Velocity (v) is a vector quantity that represents displacement (or change in position, s) over time (t), as expressed by the equation v = s/t. We refer to the rate of motion, speed, or action as velocity. A vehicle traveling at 75 miles per hour is an example of velocity. So, whether it's a moving automobile, a dropped ball, or the earth traveling around the sun, everything has velocity. We define velocity as the speed with a direction. The dog runs at a speed of 9 km/h (kilometers per hour). A negative velocity is an item that moves in the opposite direction. When an item slows down, its acceleration vector is pointed in the opposite direction as its velocity (in this case, a positive acceleration).
The initial velocity of an item defines how quickly it moves when gravity initially applies force to it. The final velocity is a vector quantity that quantifies the speed and direction of a moving body after it has attained maximum acceleration. If an item is already moving and subsequently decelerates and stops, we say that its ultimate velocity to be zero. The letter 'v' represents the final velocity, whereas the letter ‘u’ represents the initial velocity. When a moving body comes to a complete stop or if a body moves downhill at first, its velocity is negative. Whereas, if the body moves upward at first, its velocity is positive. We refer to the rapidity of motion or activity as velocity. Celerity is a synonym. The ratio of average displacement or position change (a vector quantity)to time is called average velocity. To be entirely correct, we must evaluate instantaneous velocity using calculus since approaching "instantaneous" causes lowering of time to zero.
To calculate velocity, divide the distance by the time taken to cover the distance, then multiply by the direction. For example, if you went 50 miles in one hour westward, your velocity would be 50 miles/1 hours westward or 50 miles per hour westward.
