When the length of the pendulum is the experimental variable, which 2 things are controlled variables and need to be kept unchanged?

When checking the relationship between the weight of the bob and the time for 1 cycle, what is the experimental variable?

• weight of the bob

• length of the pendulum

• amplitude

• time for 1 cycle

Which equation shows the correct way to find the average time of 3 cycles of 1.3 seconds, 1.4 seconds, and 1.8 seconds?

• average time = 1.3÷3+1.4+1.8

• average time = 1.3+1.4+1.8÷3

• average time = (1.3+1.4+1.8)÷3

• average time = 1.3 + 1.4 + 1.8

Why should you find the average time of many cycles rather than just the time for 1 cycle?

• The average is more accurate.

• The average is easier to find.

• Timing 1 cycle only is more accurate.

• You can finish more quickly.
