ΣF wagon = (m wagon + m hanging mass ) ∙ a wagon The Force of gravity is sometimes called “weight” and is equal to the mass of the object times the acceleration due to gravity (g = 9.80 m/s 2 ). Find the weight of each hanging mass. F gravity = F wt = m ∙ g = m ∙ 9.80 m/s 2 Weight of 0.025 Kg hanging mass = [ ] N Weight of 0.050 Kg hanging mass = [ ] N Weight of 0.100 Kg hanging mass = [ ] N
Analysis Questions 1. Should the force acting on the wagon be constant for all trials? Explain why or why not. [ ] 2. Was the force constant for all trials? Use data to justify your answer. [ ] Use three data range statements to justify each of the following relationship statements. 3. Write a relationship statement for the relationship between the displacement and the time when the hanging mass and wagon mass are constant. (For example, Trials 1&2 are one set of data) [ ] 4. Write a relationship statement for the relationship between the wagon mass and the acceleration when the hanging mass and displacement are constant. (For example, Trials 1, 3 & 5 are one set of data) [ ] 5. Write a relationship statement for the relationship between the hanging mass and the force when the mass of the wagon and the displacement are constant. (For example, Trials 1, 7 &13 are one set of data). [ ] 6. Write a relationship statement for the relationship between the force acting on the wagon and the mass of the wagon when the hanging mass and the displacement are constant. (For example, Trials 2, 4 & 6 are one set of data). [ ]
