What is the average speed of a person who travels 10 meters in 40 seconds?<\/strong> Understanding motion begins with the concepts of speed<\/strong>, velocity<\/strong>, and acceleration<\/strong>. These are essential for describing how objects move.<\/p>\n\n\n\n Speed<\/strong> refers to how fast something is moving. It is a scalar quantity, meaning it only tells us the magnitude, not the direction. For example, if a car moves at 60 kilometers per hour, we know its speed, but not whether it is going north, south, or another direction.<\/p>\n\n\n\n Velocity<\/strong>, however, is a vector quantity. This means it includes both the speed and the direction of motion. If that same car moves at 60 kilometers per hour to the north, then its velocity is 60 km\/h north.<\/p>\n\n\n\n Acceleration<\/strong> is how quickly velocity changes. This change can occur in three ways: an object can speed up, slow down, or change direction. Any of these changes means the object is accelerating. Even if the speed remains constant but the object turns, it is still accelerating due to the change in direction.<\/p>\n\n\n\n Different units help measure these quantities. Speed and velocity often use meters per second (m\/s) or kilometers per hour (km\/h). Since velocity includes direction, it must be stated with words like \u201cnorth\u201d or \u201cupward.\u201d Acceleration uses units such as meters per second squared (m\/s\u00b2), which means how much the velocity changes every second.<\/p>\n\n\n\n To find average speed<\/strong>, you divide the total distance traveled by the total time taken. For someone traveling 10 meters in 40 seconds, this equals 0.25 meters per second. This means the person covers a quarter of a meter every second on average.<\/p>\n\n\n\n What is the difference between speed and velocity? 2 What is acceleration? 3.

Answer:<\/strong> Speed is how fast an object is moving, while velocity is speed in a given direction.<\/p>\n\n\n\n
Answer:<\/strong> Acceleration is the rate at which velocity changes over time.<\/p>\n\n\n\n
Answer:<\/strong><\/p>\n\n\n\n\n
(a) Speed:<\/strong> meters per second (m\/s), kilometers per hour (km\/h), miles per hour (mph)
(b) Velocity:<\/strong> meters per second (m\/s), kilometers per hour (km\/h), miles per hour (mph) with direction
(c) Acceleration:<\/strong> meters per second squared (m\/s\u00b2), kilometers per hour per second (km\/h\/s), feet per second squared (ft\/s\u00b2)<\/p>\n\n\n\n
Answer:<\/strong>
Average speed = Distance \u00f7 Time = 10 meters \u00f7 40 seconds = 0.25 m\/s<\/strong><\/p>\n\n\n\n
