Physics module 1: Kinematics - Motion in a straight Line with perfect solutions 2024

Dot point #1: correct answersdescribe uniform straight-line (rectilinear) motion and uniformly accelerated motion through: - qualitative descriptions - the use of scalar and vector quantities What is motion? correct answersChanging position in space. Motion is dependant on position. What is distance? correct answersA measure of how far it is from one point to another. What is displacement? correct answersa straight line distance from the initial position to the final position. What is a scalar quantity? correct answersA measurement that only has magnitude. Give examples of scalar quantities correct answers- Mass (Kg) - Energy (J) - Speed (ms-1) - Time (t) - Distance What is a vector quantity? correct answersa quantity that has both magnitude and direction. Give examples of vector quantities correct answers- Displacement(m) - Velocity(ms-1) - Acceleration (ms-2) - Forces (N) - Weight (mg) What are the SI units and symbol for the following quantities? - Displacement - Initial velocity - Final Velocity - Acceleration - Time correct answers- S and m - u and ms-1 - v and ms-1 - a and ms-2 - t and s
