ANGELA'S PENDULUM EXPERIMENT
Angela is studying how long it takes a pendulum, a ball on a string that is tied to a stable device, to swing back and forth. She conducts several trials with the same ball, starting from the same height. She times how long it takes the ball to swing out and back to its original position each time.
The table below shows the data that Angela collected in her pendulum experiment.
ANGELA'S DATA
Trial Length of String (m) Time (s)
1 0.4 1.25
2 0.6 1.55
3 0.8 1.80
4 1.0 2.25
5 1.4 2.50
What conclusion can she draw from the table?
Group of answer choices
The longer the string, the more likely it is for the ball to stop swinging.
The shorter the string, the more time it takes the ball to swing back and forth.
The shorter the string, the less time it takes the ball to swing back and forth.
The longer the string, the less likely it is for the ball to stop swinging.

Based on the data collected in Angela's pendulum experiment, the conclusion she can draw from the table is:
The shorter the string, the less time it takes the ball to swing back and forth.
This is supported by the observation that as the length of the string increases, the time taken for the pendulum to complete a swing also increases. For example, the pendulum with a string length of 0.4 m took 1.25 seconds, while the pendulum with a string length of 1.4 m took 2.50 seconds.
