A car travels 90 meters due north – In the realm of physics, the journey of a car traveling 90 meters due north unfolds as a captivating narrative, revealing fundamental principles of motion and navigation. This exploration delves into the intricacies of distance, displacement, velocity, and speed, providing a comprehensive understanding of how these concepts govern the movement of objects.
The car’s northward trajectory serves as a poignant illustration of displacement, a vector quantity that encapsulates both the magnitude and direction of an object’s change in position. By contrasting displacement with distance, we illuminate the nuances of these closely related yet distinct concepts.
Overview: A Car Travels 90 Meters Due North
A car travels 90 meters due north. This scenario exemplifies a simple motion of an object in one dimension. It serves as a fundamental concept in physics, particularly in the study of kinematics. Understanding the distance, direction, displacement, velocity, and speed of the car provides insights into its motion and the broader principles of motion in general.
Distance and Direction
The distance traveled by the car is 90 meters. Distance is a scalar quantity that measures the length of the path traveled by an object. In this case, the car travels a distance of 90 meters in a straight line.
The direction of the car’s motion is due north. Direction is a vector quantity that indicates the orientation of an object’s motion. Due north refers to the direction directly towards the geographic North Pole.
Displacement
The displacement of the car is also 90 meters due north. Displacement is a vector quantity that measures the change in position of an object. In this case, the car’s displacement is 90 meters due north because it has moved 90 meters in that direction.
It is important to note that displacement is different from distance. Distance measures the length of the path traveled, while displacement measures the change in position. In this case, the distance and displacement are the same because the car travels in a straight line.
Velocity and Speed
The velocity of the car is 90 meters per second due north. Velocity is a vector quantity that measures the rate of change of displacement. In this case, the car’s velocity is 90 meters per second due north because it is moving 90 meters in that direction every second.
The speed of the car is 90 meters per second. Speed is a scalar quantity that measures the rate at which an object travels. In this case, the car’s speed is 90 meters per second because it is traveling 90 meters every second.
It is important to note that velocity and speed are different. Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only measures the rate of travel.

Top FAQs
What is the difference between distance and displacement?
Distance refers to the total length of the path traveled by an object, while displacement represents the net change in the object’s position, considering both magnitude and direction.
How is velocity calculated?
Velocity is a vector quantity that incorporates both speed and direction. It is calculated by dividing the displacement of an object by the time taken to complete that displacement.
What practical applications do these concepts have?
These concepts find application in navigation systems, engineering design, projectile motion calculations, and even in understanding the movement of celestial bodies.
