Lab #9.1 Mechanics: Chapter 9  An Uphill Climb
Lab #9.1 Mechanics: Chapter 9 An Uphill Climb

PurposeIn this experiment, you will determine what advantage—if any—there is in using an inclined plane to move an object to a higher elevation. DiscussionWhy are ramps used when lifting heavy objects? Does it make the task easier (requires less force)?...

Lab #6.3b Mechanics: Chapter 6  the Weight
Lab #6.3b Mechanics: Chapter 6 the Weight

Purpose In this activity, you will investigate the relationship between weight and mass. Discussion Mass and weight are different quantities. Mass is a measure of an object's inertia, the extent to which an object resists changes to its state of...

Lab #6.3a Mechanics: Chapter 6  Putting the Force Before the Cart
Lab #6.3a Mechanics: Chapter 6 Putting the Force Before the Cart

Purpose In this activity, you will observe the motion of a variety of objects under a variety of conditions. You will interpret your observations to learn the relationship between force, mass, and acceleration. Discussion Some of the most fundamental laws...

Lab #5.5 Mechanics: Chapter 5  The Big BB Race
Lab #5.5 Mechanics: Chapter 5 The Big BB Race

Purpose In this activity, you will compare the path of a projectile launched horizontally with that of an object in free fall.DiscussionSuppose a ball bearing (BB) were launched horizontally at the same time another BB were dropped from the same...

Lab #4.7 Mechanics: Chapter 4  Sonic Ranger
Lab #4.7 Mechanics: Chapter 4 Sonic Ranger

Purpose In this activity, you will use graphs to investigate motion. The graphs will represent your own motion and will be drawn by the computer as you move. Discussion Graphs can be used to represent motion. For example, if you...

Lab # 4.1 Mechanics: Chapter 2  Go! Go! Go!
Lab # 4.1 Mechanics: Chapter 2 Go! Go! Go!

Purpose In this experiment, you will plot a graph that represents the motion of an object. Discussion Sometimes two quantities are related to each other, and the relationship is easy to see. Sometimes the relationship is harder to see. In...

Lab # 2.1   Mechanics:  Walking the Plank
Lab # 2.1 Mechanics: Walking the Plank

Purpose In this activity, students will measure and interpret the forces acting on an object when the object is in equilibrium. Discussion Consider two sign painters who work on a scaffold (a plank of wood suspended by ropes at both...
