Thanks again for the help! -MC
You're welcome! Let's check the answers and also understand how we arrived at them:
1. Average speed is the distance an object travels divided by the time it takes.
To calculate the average speed, you need to divide the total distance covered by an object by the time it took to cover that distance. For example, if an object travels a total distance of 100 kilometers in 5 hours, the average speed would be 100 km / 5 h = 20 km/h.
2. The velocity of an object is its speed in a certain direction.
Velocity is a vector quantity that includes both the speed of an object and its direction. Speed refers to how fast an object is moving, while direction refers to the path it is taking. For example, if a car is moving at a speed of 60 km/h towards the north, its velocity would be 60 km/h north.
3. The steepness of the line on a position-time graph measures the object's speed.
In a position-time graph, the slope or steepness of the line represents the object's speed. The steeper the line, the greater the speed of the object. On the other hand, a horizontal line on the graph indicates that the object is at rest and has zero speed.
4. Displacement always includes a direction and is used in measuring velocity.
Displacement refers to the change in position of an object from its initial point to its final point. It is a vector quantity that not only considers the distance covered but also the direction of the movement. Displacement is used in measuring velocity because velocity is the rate at which an object's displacement changes with time.
