Two crates, one heavy and one light, are at rest on a waxed floor. Which crate will need the greater force to give the same change in speed? Explain.

The heavy one because mass times force is equal to speed. The lighter one has less mass to it goes faster without as much effort. I hope that helps!

Explanation:

Force is defined as the multiplication of mass and acceleration.

Mathematically,        F = m × a

where              m = mass

                        a = acceleration

This relation clearly indicates that force is directly proportional to mass. That is more is the mass of an object more will be the force required to move the object from its initial position.

Hence, we can conclude that heavy crate will need greater force to give the same change in speed.
