| (a) |
Provide examples of objects that exhibit, or appear to exhibit, uniform motion. (K) |
| (b) |
Discuss the concept of 'frame of reference' in determining whether an object is in motion and in constructing representations of an object's motion. (S, K, A) |
| (c) |
Construct scale diagrams of displacement vectors (i.e., collinear, non-collinear [perpendicular], and non-collinear [non-perpendicular]) to represent changes in an object's position. (S, A) |
| (d) |
Design and carry out experiments to determine the properties of uniform motion, using technologies such as photogates, motion detectors, ticker timers and stopwatches to collect distance and time data effectively and accurately. (S, STSE, A) |
| (e) |
Discuss the importance of distinguishing between scalar (e.g., distance, speed and time) and vector (e.g., position, displacement, velocity and acceleration) quantities when studying motion. (K) |
| (f) |
Construct and analyze graphs (i.e., distance-time, position-time, speed-time and velocity-time) using student-collected data obtained from objects undergoing uniform motion or through computer simulations. (S, A) |
| (g) |
Describe quantitatively the relationship among distance, time and speed for everyday objects that undergo uniform motion. (K) |
| (h) |
Derive the relationship between speed, distance and time (i.e., $v={\Δd}/{\Δt}$) and between velocity, displacement and time (i.e., $v ↖ {→}={\Δd ↖ {→}}/{\Δt}$) using student-collected data from objects undergoing uniform motion. |
| (b) |
Solve problems related to the motion of objects that travel at a constant speed in a straight line. (S) |
