Forces and Motion

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.
