A body is said to be moving with a non-uniform speed.
Example of direction and velocity. 11 Give examples of motion in which the directions of the velocity and. Instead velocity refers to the time interval it takes for an object to move in a certain direction. In this case acceleration happens in such a manner that the velocity is increasing with the direction changed.
We observe that the viscous force is proportional to the velocity of the object and it is opposite to the direction of motion. Pages 30 Ratings 67 3 2 out of 3 people found this document helpful. Saying Ariel the Dog runs at 9 kmh kilometers per hour is a speed.
A body is said to be moving with a non-uniform speed when the speed of the body changes with time. Velocity is a vector quantity. There are three instances when acceleration can happen.
Examples of Speed and Velocity. The speed and direction of motion of a moving body. For example if you traveled 50 miles in 1 hour going west then your velocity would be 50 miles1 hour westwards or 50 mph westwards.
A volleyball is served up and to the right at an angle 30circ with a speed of 243 ms as seen below. It moves at constant speed but its velocity is constantly changing since its direction is always changing. An example of velocity is a car driving at 75 miles per hour.
Velocity is speed with a direction. Add the quantity obtained from Step 1 and Step 2 to obtain the final velocity. First there is constant velocity but a change in direction.
