Kinematics Uniform Motion How can uniform motion be I. Any object moving at a constant velocity expressed and how can it be II. When graphed, the line of best fit represents the average speed calculated? a. y = mx + b; where ?m? is the constant (slope) and ?b? is the initial value b. velocity = displacement / time (m/s) Vectors and Scalars What is the difference betw- I. A vector is a measurement that has a direction component een a vector and a scalar? a. Velocity and displacement are vector quantities (e.g. 5 km/h [S]) II. Speed and distance are scalar quantities (e.g. 15 m away) Uniform Acceleration What is uniform acceleration I. Accelerated motion (non-uniform) occurs when an object travelling in a
