Another thing I noticed was that the father seemed taller and bigger than the child. Finally, I noticed that the bicycles made a noise when the brake was being used. / I think that knowing when something has more mass, it will make it harder for other objects or people to make it stop if it was moving. - Aime O]]> 2020-11-16 21:07:44 UTC https://padlet.com/canderson257/9z5cujs20lyb7n7p/wish/929312492 giselle_mora1 https://padlet.com/canderson257/9z5cujs20lyb7n7p/wish/929314022 One thing I noticed was that Paul's father stopped slower.

2) For paul it was not as hard to stop to bike from moving since hes smaller and weighs less.
