Why is it harder to move an object up a hill at 90 degrees than at 20 degrees?

While, if the hill is 90 degrees, then it is a cliff. That is to say, that you are not receiving any "help" from the 90 degree hill. You are just lifting the object straight up. Whereas the 20 degree hill provides a ramp.

What makes an object move?
The force of gravity acts on an object if it's on a hill. if it is not then it takes another force, such as a push or pull, to move the object.
Why would a streamlined object be able to move faster than an object that wasn't?
Because when an object is streamlined it becomes smoother so the air becomes weaker and the object becomes stronger to move, but if the object is not streamlined it becomes slower because the air resistance is holding it back so its harder to move with a certain speed. +++ Not quite. The air does not become "weaker", nor does the object become "stronger" to move. The second part is right, and can also be stated as streamlining reduces the air resistance acting on it so reducing the force needed to move it at any given speed.
How can object move?
Object's can move in different ways.Some one can push a object to move it. They can Pick it up and move the object.Machinery can move objects also. And wind can move object's if it is blowing hard enough.
How do electrons move?
Electrons can move from atom to atom and from object to object
Why is friction greatest when an object is stationary?
Because the frictional force must be greater than forces that would cause the object to move. Example: a car parked on a slope does not move despite the force of gravity acting to pull it down the hill. Why? Because the frictional forces are greater than the forces of gravity.

Does mass affect the movementof an object?
Yes. The heavier it is the harder it is to move or if you throw it the less amount of time it will be in the air for. C.Burgess
What force makes it harder to move things?
Friction makes it harder to move things.

Can nonliving things move?
Technically, yes, nonliving things can move. There is a wheel (a nonliving object) that, when on a slope, rolls down a hill, which is considered motion, which is technically moving. Plus, a robot has the ability to move on its own and sense the things around it. Though, contrary to the above answer, a tissue box on a level surface with no unbalanced forces cannot move on its own. Even though a robot is an inanimate object, technically speaking, it can move.
What is the slowest speed an object can move?
The slowest speed an object can move is zero.
Why is friction greatest when an object is stationary?
Because the frictional force must be greater than forces that would cause the object to move. Example: a car parked on a slope does not move despite the force of gravity acting to pull it down the hill. Why? Because the frictional forces are greater than the forces of gravity.
What hill will make two balls move slow?
A steep hill
Why is labour unwilling to move?
