OBJECTIVE 4 Experimental Investigation
OBJECTIVE 5 Data Analysis & Making Conclusions
Method
1. The student put masses on the sledge and pulled it gently with a Newton metre, to measure the
force needed until it just started to move. (Force is measured in units called Newtons or N.)
2. The student recorded the force shown by the Newton metre which was needed to move the sledge.
3. Extra masses were then added to the sledge to make it heavier.
4. The student recorded the force needed to move the heavier sledge.
5. The student collected 5 sets of results, using different masses.
a. Use the graph grid to draw a graph of the results, plotting MASS in grams against FORCE in
Newtons. (Decide what sort of graph is best and then decide whether mass or force should be
plotted on the ‘y’ or ‘x’ axes.)

b) Study the graph which you have drawn and write a conclusion about what it shows.
