Have you ever wondered which bowling ball to choose at a bowling alley and noticed that the heavier the ball the more pins you knocked down?
This is because the mass changes and increases the object force.
Watch this video about how much force is needed to move a large mass in sports:
Pay attention to how much mass the heavy bag has and how little it moves compared to the test dummy.
Answer these questions in your notebook:
Did it look easier to move the 300 pound bag or the smaller test dummy?
How do you think this idea of mass applies to our roller coasters in science class?
Would anything change if we used a clay ball in place of a marble?
There is more to learn about force and motion using roller coasters. Let's watch these two kids explore science with rollercoasters.... While you are watching it, take some notes in your science notebook or on a piece of paper.
