The correct answer and explanation is:
The correct answer is d. reference point.
Explanation:
A reference point is a fixed place or object used to determine if another object is in motion. It serves as a baseline or starting point from which the movement of an object can be observed and measured. Without a reference point, it is impossible to tell if an object has changed position because movement is always relative.
For example, when you see a car moving on a road, you know it is moving because you compare its position to fixed objects around it, such as trees, buildings, or signs. These objects serve as reference points. If the car’s position changes relative to these points, then it is moving.
In physics, motion is defined as a change in position of an object with respect to a reference point over time. The reference point itself is usually considered stationary, so it provides a frame of reference. The choice of reference point depends on the context and what is considered fixed in the situation.
The other options are related concepts but do not serve as a basis for measuring movement:
- Meter (a): The meter is a unit of length or distance, not a baseline for observing movement.
- Force (b): Force is a push or pull acting on an object, causing it to accelerate, but it is not a basis for measuring movement.
- Speed (c): Speed is a measure of how fast an object moves, but it requires a reference point to determine displacement.
In summary, without a reference point, we cannot determine whether an object has moved. Motion is always described relative to a reference point, making it fundamental in understanding and measuring movement.
