This term we've been exploring forces...Today we've been exploring the effects of gravity and mass on momentum, acceleration p, and velocity.
We have started building our own loop-the-look 'roller coaster' marble runs and have been predicting how different balls will fare through the loop.
We predict that the greater the mass to surface area ratio then the quicker the ball will travel. This is because there will be less friction and air resistance affecting the ball's travel.
