Summary: Motion is physics.
You decide if something is moving by using a reference point. A reference point is the point in which you are using to tell whether the person or thing is moving or not. If something is moving, then the distance between its reference point and itself is different than it was before. Distance is the scalar quantity in between two point while displacement is a VECTOR quantity and is the able to be defined by using a distance concept. The difference between Scalars & Vectors are that Vectors are quantities that are completely described by both direction and a magnitude while a Scalar is only fully described by a Magnitude such as a numerical value.
SP4: Analyzing and interpreting data: I used data from an experiment or small lab that we did in class to find the displacement and distance in the different steps and directions we walked. We also used the pythagorean theorem to help find the displacement in some of our steps. A pattern we noticed was that the distance was always bigger than the displacement.
