Final answer:
Forces are interactions between objects that cause a change in motion. There are two options that are not true about forces: 'amount of matter in an object' and 'measured on kilograms'.
Step-by-step explanation:
Forces are interactions between objects that cause a change in motion. There are several characteristics of forces that are not true. The first option, 'amount of matter in an object,' is not true because the amount of matter in an object is not related to the force exerted on it. Another incorrect option is 'measured on kilograms,' as force is actually measured in units called newtons, not kilograms.
