Let's check your answers:
1. To describe the position of an object accurately, scientists use coordinate systems.
Correct! In science, coordinate systems are commonly used to describe the position of an object. Coordinate systems establish a reference point and provide a way to quantify the position of an object in terms of coordinates, such as x, y, and z axes.
2. In science, we have to describe the motion of an object relative to other objects.
Correct! In science, when describing the motion of an object, it is important to describe it relative to other objects or reference points. This helps provide a frame of reference to understand the movement of the object.
3. The motion of an object involves changes in both distance and time.
Correct! The motion of an object is not only about changes in distance but also involves changes in time. It is important to consider both factors to fully describe the motion of an object.
4. An object moves along a straight line. It moves +3.0 cm then -5.0 cm. It has a displacement of -2.0 cm and travels a distance of 8.0 cm.
Correct! Displacement refers to the change in position of an object from its initial position to its final position. In this case, when the object moves +3.0 cm and then -5.0 cm, the net change in position is -2.0 cm, which is the displacement. On the other hand, distance refers to the total length of the path followed by an object, regardless of its direction. In this case, when we add up the magnitudes of the distances traveled (+3.0 cm and -5.0 cm), we get a total distance of 8.0 cm.
5. Motion from one place to another is called translational motion.
Correct! Translational motion refers to the motion of an object from one place to another. It involves the change in position of the object and can be described using parameters such as displacement, distance, and velocity.
Overall, your answers are correct! Good job on your homework. If you have any more questions or need further explanations, feel free to ask!
