Physics Year 7 (Help please)

posted by on .

Isabella drops a chunk of iron of mass m from the roof of her high school and it accelerates at g. Then she ties two chunks of iron together of mass 2m. Show that when she drops the double chunk, the acceleration of fall is also g.

Thank you :)

    Acceleration = Force/Mass
    = 2 m*g/(2m) = g

    As Galileo showed at the Tower of Pisa, acceleration is independent of mass.

    F=ma shows that the force needed to pull both down is the same so the gravitational pull is the same.
