It is much more difficult to move a dresser full of clothes than an empty dresser. Why?
An object in motion stays in motion.
It takes more force to move an object with more mass.
It takes more friction to move the empty dresser.

Would a person weight less on Mars or on Earth?
They would weigh the same on both locations
They would weigh less on Mars cause it has less gravity
They would weigh less on Earth cause it has more gravity
They would weigh more on Mars cause it has more gravity
