Experiment: Activity 1 - Mass vs Friction

Complete pg 3 on your own by tomorrow. I'll go through the answers in class tomorrow and further explain on your observations in today's experiment.

Important points to take note in today's experiment

• Aim: To infer the relationship between the amount of force needed to move stationary objects(s) and the mass of the object(s).
• We tried out Block A & B of the same size and mass in our experiment today. 
• We observed that when Block B was added to Block A, we need even more weights to move the both blocks. [This is an observation]
• What can you conclude from the experiment? The greater the mass of the objects, the greater the amount of force needed to move these objects. [This is a conclusion]
• We repeated the experiment 3 times and recorded 3 readings before taking the average. This is to ensure reliability and consistency in the results.
