1. Physics 1 Module #5 Supporting Standards

2. Speed, Velocity, Acceleration Speed is the total distance/total time. Measured as m/sec or km/hr. The hiker in the graph had An average speed of 5 hours5000 m = 1000 m/hr Readiness

3. Velocity Velocity is the speed of an object in a specific direction. Measured as m/sec and direction like north, south, etc. Example: The airplane travels at 500 km/hour to the East.

4. Acceleration Acceleration is changing directions or speed which includes slowing down or speeding up. 2 Measured as m/sec 2

5. Calculating Average Speed Use the Speed= total distance/total time formula from the science chart. Find your total distance from the graph, data table, or story problem and divide. Remember: Distance goes inside the house. Readiness Distance Time

6. Calculating Average Speed Using a graph, find the last point on the graph. Find total distance and total time. Set up your division correctly. Divide and solve.

7. Motion Graphs Identify different types of motion on a distance/time graph and a speed graph including constant speed, velocity, and acceleration. Readiness Note: This is a distance/time graph.

8. Motion graphs Note that this is a velocity/time graph. This graph means something completely different from the graph you just studied on the previous page. What are the differences?

9. Potential and Kinetic Energy Compare and Contrast Potential and Kinetic Energy. Potential energy is the energy of position. If an object is high off the ground, it has potential. It a rock is pulled back in a sling-shot, then it has potential. Kinetic energy is the energy of motion. If an object is moving it has kinetic energy. If it is going fast, it has high kinetic energy. If it is going slow it has low kinetic energy. Readiness

10. Potential and Kinetic Energy

11. Energy Transformations Energy transforms into other types of energy. For example, in a flash light, chemical energy (battery) turns into electrical (light switch and wires) which then turns into light energy (light shining from flashlight). Readiness

12. Work Pushing a box up a ramp to the back of a truck is the same amount of work as lifting it up to the back of a truck. You just use less force when you use the ramp. Work = force x distance (use science chart to calculate work) An object has to move a certain amount of distance for their to be work. You also have to apply force. Example: 20N x 0 m = 0 J Readiness
