Answer :
To describe an object's motion accurately, you must know:
1. Its change in position: Understanding how the object moves from one place to another is crucial. This includes knowing the direction, distance, and speed at which the object travels.
2. Its speed and velocity: Speed refers to how fast an object is moving, while velocity adds the component of direction to speed. Both speed and velocity are essential for describing motion.
3. Its acceleration: Acceleration is the rate of change of velocity over time. It tells us how quickly an object's velocity is changing, either in terms of speeding up, slowing down, or changing direction.
4. Its trajectory: The path an object follows while in motion. This could be a straight line, a curve, a circle, or any other shape depending on the forces acting on the object.
5. Forces acting on the object: Understanding the forces, such as gravity, friction, or applied forces, that influence the object's motion is crucial. These forces determine how the object moves and changes its state of motion.
By knowing these factors, you can accurately describe an object's motion, predict its future behavior, and analyze the forces at play during its movement.
