#### Question

A whole brick has more mass than half a brick; thus, the whole brick is harder to accelerate. Given this fact, why doesn't a whole brick fall with a lower acceleration than half a brick? Explain.

#### Step 1

1 of 3

According to $\textbf{Newton's second law}$, the whole brick is harder to accelerate than half a brick, which means that we need more force to accelerate the whole brick than what we need to accelerate half a brick.

But since the force exerted by gravity on a whole brick is greater than the force exerted by gravity on half a brick in a way that it is proportional to the mass;

Thus, the acceleration due to gravity is always constant (for a certain planet's surface).
