…Average speed is the measure of how fast an object is moving, taking into account the distance traveled and the time it took to travel that distance. It is calculated by dividing the total distance traveled by the total time taken.
No, average speed and instantaneous speed are different concepts. Average speed is the overall speed of an object over a period of time, while instantaneous speed is the speed of an object at a specific moment in time.
Yes, average speed can be negative if the object is moving in the opposite direction of the positive direction used in the calculation. For example, if an object travels 10 meters north and then 5 meters south, its average speed would be -5 meters per second.
The most commonly used units for average speed are meters per second (m/s) and kilometers per hour (km/h). However, other units such as miles per hour (mph) and feet per second (ft/s) can also be used depending on the situation.
Changing the time interval does not affect the calculated average speed, as long as the total distance traveled remains the same. This is because average speed is a measure of the overall speed of an object, not the speed at a specific moment in time.
