Today we used a force to move an object.
Prediction: We predicted that the different sized and different weight balls would take different amounts of force to make them move the same distance (1metre)
Results: The tennis ball took the most number of breathes to go one metre. The golf ball took a few less breathes and the ping pong ball took the least number of breathes to go one metre.
Conclusion: This is because the heavier the object is, the more force is needed to move it.
