3.The motion of an object involves changes in both distance and what?
Ans- time
4.An object moves along a straight line. It moves +3.0 cm then -5.0 cm. It has a ____________ of -2.0 cm and travels a ____________ of 8.0 cm.
Ans- displacement; distance
5.Motion from one place to another is called ____________ motion. Ans- translational

1. To describe the position of an object accurately, scientists use coordinate systems.
- Yes, your answer is correct. Scientists use coordinate systems to accurately describe the position of an object. These systems typically involve a reference point and a set of axes (such as x, y, and z) to specify the position in three-dimensional space.
2. In science, we have to describe the motion of an object relative to other objects.
- Yes, your answer is correct. When describing the motion of an object, it is important to consider its motion in relation to other objects or a specific reference point. This allows scientists to determine the object's position, speed, and direction with respect to its surroundings.
3. The motion of an object involves changes in both distance and time.
- Yes, your answer is correct. The motion of an object encompasses changes in both distance and time. Distance refers to the actual path traveled by the object, while time measures the duration of the motion. By analyzing the changes in distance and time, scientists can determine various aspects of the object's motion, such as speed, acceleration, and displacement.
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.
- Yes, your answer is correct. Displacement refers to the change in position of an object. In this case, the object moves +3.0 cm (forward) and then -5.0 cm (backward). The resulting displacement is -2.0 cm, indicating that the object ended up 2.0 cm back from its initial position. Distance, on the other hand, refers to the total path traveled by the object. Thus, the total distance traveled is 8.0 cm, obtained by adding the magnitudes of the individual displacements.
5. Motion from one place to another is called translational motion.
- Yes, your answer is correct. Translational motion refers to the movement of an object from one place to another in a straight line. It is the type of motion commonly observed in everyday situations, such as walking, driving, or throwing a ball.
