Final answer:
Velocity is defined as the rate at which an object changes its position with respect to time. It has both magnitude and direction. Examples of velocity include a car moving at a constant speed on a highway and a ball being thrown vertically upward and then falling downward.
Step-by-step explanation:
Velocity is defined as the rate at which an object changes its position with respect to time. It is a vector quantity, meaning it has both magnitude and direction.
An example of a picture that identifies velocity is a car moving at a constant speed of 60 miles per hour on a highway. The car's velocity is 60 miles per hour in the forward direction.
Another example is a ball being thrown vertically upward. As it moves upward, its velocity decreases until it reaches its highest point, where its velocity is zero. Then, as it falls downward, its velocity increases in the downward direction.
