just tell me the answers in a very very short sentence, no explanation

Answer 1

1. Scientists describe motion in terms of position, velocity, and acceleration.
2. Three kinds of motion are linear (car driving), circular (planet orbiting), and oscillatory (pendulum swinging).
3. Scientists describe position using coordinates relative to a reference point.
4. A one-dimensional coordinate system uses a single axis to indicate position and direction.
5. Distance is the total path traveled; displacement is the straight-line distance from the start to the end point.
6. Displacement is calculated as the final position minus the initial position.
7. Changes in time are calculated by subtracting the initial time from the final time.
8. A steeper line in a displacement vs. time graph represents a higher speed.
9. Cartesian coordinate systems describe points in space using x and y coordinates; they can be interpreted by locating points on a grid.
