A change in an object’s position is called * 1 point a. force b. motion c. pulling d. pushin
The correct answer and explanation is:
Correct Answer: b. motion
Explanation (300 words):
A change in an object’s position with respect to time and a reference point is known as motion. In physics, motion refers to the movement of an object from one location to another, and it can be described in terms of speed, direction, velocity, and acceleration.
When we observe something moving—like a car driving down a road, a leaf falling from a tree, or a person walking—we are witnessing motion. This movement means that the object has changed its position relative to a specific point or frame of reference, such as the ground or a nearby object.
There are several types of motion, including:
- Linear motion – moving in a straight line (e.g., a train on tracks)
- Rotational motion – spinning around an axis (e.g., a spinning wheel)
- Oscillatory motion – moving back and forth (e.g., a pendulum)
- Projectile motion – curved path under gravity (e.g., a thrown ball)
Let’s clarify the incorrect options:
- a. Force: A force is a push or pull that can cause an object to move, stop, or change direction, but it is not the motion itself. Force can lead to motion, but it is a separate concept.
- c. Pulling and d. Pushing: These are types of forces. They describe ways in which motion might be initiated, but they are not the definition of motion.
In summary, motion is the term that describes a change in an object’s position over time. Understanding motion is essential in physics because it helps us analyze how and why objects move and interact with forces in their environment.
