It seems like you are trying to fill in the blanks in a statement about the relationship between mass, force, and motion. Here’s a possible way to complete the statement:
"An object with more mass changes in motion more, so it requires more force to accelerate at the same rate."
So the completed sentence would be: "An object with more mass changes in motion more, so it requires more force to accelerate at the same rate."
If you need help with something else or further explanation, feel free to ask!
