Momentum Video

When two objects with similar air resistance are dropped from the same height at the same time, they will

• Hit the ground at the same time

• Hit the ground at different times, with the object with more mass hitting first

• Hit the ground at different times, with the object with less mass hitting first

They hit the ground at the same time because:

• Acceleration due to gravity is constant

• Acceleration due to gravity depends on mass

• Velocity due to gravity depends on mass

What do you think would happen if the smaller ball was dropped below the larger ball?

What do you think will happen?

• 1 ball will come out twice as fast

• 2 balls will come out at the same speed
