What does a ramp reduce?
It reduces the amount of lifting force and also reduces the wind energy of all of the substances and molecules in the prototype (the item that you're moving)
How can you decrease the effort force needed to push a weight to the top of a ramp?
Lengthen the ramp, decrease the mass of the object, use a machine (e.g., a block and tackle) to pull the weight up the ramp, reduce the friction of the weight against the ramp, move the ramp further from the center of gravity of the earth, submerge the ramp in a liquid...tbere may be more ways but this should give you some ideas to consider.
What will happen to the effort force if the height of a ramp is increase?
More force will be required to push an object along the ramp.
What if The force of friction acting on a cart on a ramp is exactly balanced by the force of gravity acting on the cart down the ramp?
The cart stays where it is and doesn't move.
Which would best reduce the amount of energy need to pull a wagon up ramp?
A

What is an Egyptian ramp?
An Egyptian ramp is a ramp with a platform in the middle to reduce the incline of the ramp and/or to change the direction of incline.
When a ramp is at a angle of 10.5 degrees what will be the applied force?
The applied force will depend on the required force, and the angle to the ramp (or the horizontal) at which the force is applied.
With how much force does a ramp push a ball rolling down it?
A ramp exerts no force, just gravity.
How can you decrease the effort force needed to push a weight to the top of a ramp?
Lengthen the ramp, decrease the mass of the object, use a machine (e.g., a block and tackle) to pull the weight up the ramp, reduce the friction of the weight against the ramp, move the ramp further from the center of gravity of the earth, submerge the ramp in a liquid...tbere may be more ways but this should give you some ideas to consider.
Does a ramp reduce the amount of work being done in science?
No. It reduces the amount of force required, but it does not reduce the total amount of work. In fact, due to friction, it will probably increase the total amount of work.
What will happen to the effort force if the height of a ramp is increase?
More force will be required to push an object along the ramp.
Why does a ramp not reduce the amount of work. Please explain in words or with numbers?
Assuming 100% efficiency, the amount of work depends on the weight and the vertical distance (that is, opposite to the pull of gravity) moved. If you use a ramp then you reduce the force by an amount k, that's true, but the distance you have to push in the direction of the force is multiplied by k. The work done is [original force]/k times [vertical distance]times k and the k cancels out. For vertical lifting k=1.
What if The force of friction acting on a cart on a ramp is exactly balanced by the force of gravity acting on the cart down the ramp?
The cart stays where it is and doesn't move.
How do you increase the efficiency of pushing a concrete block up a wooden ramp?
Reduce the friction of it and the ramp, for example, mounting it on wheels.
How would the input force needed to push a wheelchair up a ramp change if you increase the height of the ramp but not its length?
The input force would increase as the height of the ramp increased. It wouldn't matter the distance. Ask me another one.
Which is the main force that causes a toy car to roll down a ramp?
The gravitational force is.
