1. Without are resistance, why do objects with different masses fall at the same speed?

Answer:

Using the relationship to reinforce the understanding

acceleration = forcemass

For the smaller mass, the force is 20 N and the mass is 2 kg, so:

2 kg10 m s-2 = 20 N

For the smaller mass, the force is 40 N and the mass is 4 kg, so:

4 kg10 m s-2 = 40 N

Both objects fall with an acceleration of about 10 metre second-2.

This is often referred to as the acceleration due to gravity and is the value obtained if the air resistance force acting on the falling object is negligible.

Answer:

They think that gravity acts more on a heavier object thus pulling it down faster. In fact, gravity works independently of mass. This means that all objects should fall at the same rate. ... If there is no air resistance, or the same amount of air resistance, then objects of the same mass will fall at the same rate.
