A change in an object’s position is called a. Force b. motion c. pulling d. pushing
The correct answer and explanation is:
The correct answer is b. motion.
Explanation:
A change in an object’s position refers to the object moving from one place to another. This concept is called motion in physics.
Motion is the process by which an object changes its location or position over time. Whenever an object moves from its original place to a different place, it is said to be in motion. Motion can be described in terms of distance, displacement, speed, velocity, and acceleration.
- Force (option a) is related but different; it is a push or pull upon an object resulting from its interaction with another object. Force can cause motion, but force itself is not the change in position.
- Pulling (option c) and pushing (option d) are types of forces. When you pull or push an object, you apply a force to it, which may cause it to move. But pulling or pushing are actions, not the change in position itself.
To better understand motion, consider a simple example: If you push a ball on the ground, it starts rolling. The ball’s change from one spot to another is its motion. The push you apply is a force that causes the ball to move, but the actual change in the ball’s position is called motion.
In physics, motion can be classified in different ways:
- Linear motion: movement in a straight line.
- Rotational motion: movement around an axis.
- Oscillatory motion: back-and-forth movement, like a pendulum.
Motion is a fundamental concept in physics because it describes how objects move in the universe. The study of motion without regard to its causes is called kinematics, while the study of motion and its causes (forces) is called dynamics.
In summary, the change in an object’s position is known as motion because motion precisely means that an object has moved from one location to another. Forces like pushing or pulling can cause motion, but motion itself is the outcome—the actual change in position.
