It depends. If you want to lift them up, you have to act a force equal to their weight, so a heavier person would need a force with greater magnitude. If you want to move them horizontally on a plane with friction the heavier person needs a force with greater magnitude again. On a plane without friction no force needs to be acting on them in order to move.

What is the net force on a force gauge?
If the force gauge isn't moving, the the net force must needs be zero.
What is the net force on the force gauge?
If the force gauge isn't moving, the the net force must needs be zero.
How much force 20n needs from not moving?
To counteract a force of 20 N, you need another force, also of 20 N, in the opposite direction.
Desciption of newtons first law of motion in everyday terms?
Anything that's moving keeps moving in a straight line at constant speed, unless a force acts on it.Anything that's not moving can't start moving, unless a force acts on it.Any change of speed or direction needs a force to make it happen.
Which needs more force to lift one book or two books?
Anything that registers a bigger number on a bathroom scale needs more force to lift it. That's going to be two books, compared to one book.
When the box is moving it experiences a friction force of 20 N to the left or toward the mover What force does the mover need to apply in order to keep the box moving to the right at 1 m s?
Since the box not having any acceleration and is moving with constant velocity the net force on the box is zero. Therefore the mover needs to apply a force of 20 N.
Why do cars need petrol if uniform motion requires no resultant force?
A moving object always experiences drag, a unbalanced force slowing it down. Thus it needs a force provided by the engine to counteract this force. The engine doesn't go without petrol (or some other appropriate fuel) so a car needs that as well.
What is slididng friction?
Static friction is the side force between objects that needs to be overcome to move it; sliding friction is the side force between objects that needs to be overcome to keep it moving once it starts to move, and is generally lower than static frictionmove it
When a block is moved on a surface there is an equal and opposite force acting on it - Newton's Third law- therefore the net force is zero the how does the block moves?
-- The equal and opposite forces on it are the vertical forces ... the weight of the block downward and the normal, constraint force of the surface upward. Since the vertical forces are equal and opposite, the net vertical force on the object is zero, and it has no vertical acceleration. -- Nobody ever said that the block needs force to keep moving. In fact, it doesn't. Once it's moving horizontally, no force is needed to keep it moving horizontally. If it weren't for that pesky friction where it touches the surface, it would keep moving forever with no force on it.
Why does apes have bigger mouths then humans?
Apes eat coarser foods, so they need sturdier teeth. Bigger teeth needs bigger jaws, and bigger jaws needs bigger mouths.
What is the net force a person?
Just as with other object, you can deduce the net force using Newton's Second Law. If an object - a person in this case - is at rest (or moving at a constant velocity), the net force must needs be zero. Only if the person is accelerating will there be a non-zero net force.
Is a female bunny bigger than a male bunny?
Usually. She needs to be able to have babies, so she needs to be bigger.
