Two ways to think about this:
From Newton's Second Law: F=ma, a=F/m. Since the mass is in the denominator, a large mass means a small acceleration. In other words, for a given force, it will take a long time to change its velocity. (There will also be a lot of friction, so some items can't be moved at all.)
From kinetic energy calculations: KE = (1/2)mv2, so more mass means more kinetic energy for a given speed. It takes a lot of energy to make something big move.
In any case, it is not the SIZE of the object that matters, but rather its MASS.

Do objects that move in space ever slow down?
No and yes. All objects in space move, but the gravity of the sun and the planets slow down a spacecraft or other object if they get too close.
How does friction affect a way objects move?
Friction will slow down the moving object
What 2 objects oppose to forces and slow objects?
Strictly speaking, the only thing that opposes to force and slows objects in all scenarios is friction. If you are trying to move an object upwards, gravity is a downward force and as such is capable of doing opposing upwards forces and causing the object to slow down as well
Why do some objects move continuously while some moving objects stop suddenly?
Because of friction, Friction is what causes moving objects to slow down and eventually stop. This is an important science idea we can use to describe the force that pushes back on a moving object and makes it slow down and stop.
Objects in space continue to move because there is no?
force in the opposing direction (Newtons first law). There are no gas molecules so no drag or 'wind resistance' to slow the objects down. RESISTANCE

What do you do with a inclined plane?
it makes it easier to move objects (usually heavy, large, hard to move, etc) to an area with a higher elevation
Why are they assuming the large molecules will stay on their own side of the membrane?
Because they are to big and move to slow

What objects snap to when you move them?
What do objects snap to when you move them
What large mass of frozen water can move rocks and boulders moves slow and changes the earth?
It is a diamond
Why do objects in space continue to move in a straight line at a constant speed?
Because there is no air in space, there is no friction to slow said object down.
What is the name for the study of why objects move?
The study of why objects move is dynamics, whereas the study of how objects move is kinematics.
