How do the length and the height of a ramp affect the amount of force needed to raise a load?
The height and length give an inclination angle. If you assume a straight ramp, this angle is arctan(height/length). Beware: length is measured over ground, i.e. horizontally. The force needed to raise a mass over such an ramp is sin(angle)*mass*gravitational_constant Beware: friction neglected here, example: steel ball rolling up a extreme hard, flat surface. The force of gravity acts vertically downwards on the object, and it is the component of this force down the slope that has to be overcome in order to raise the load, plus any frictional force opposing the movement. The applied force will be least if the force is directed parallel to the slope
How will the angle of the ramp affect the speed of the marble?
if its steeper it'll go faster
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 lenght?
The effort needed would increase.
How does ramp angle affect speed?
it affects speed because it could make it go slower or faster
How does an inclined plane reduce the amount of input force needed?
Because the force of gravity is no longer straight down on the object, it is at an angle. thus when you have a ramp some of the force due to gravity is dispersed in the x plane, causing the force down on the y plane (vertical) due to gravity ( mass x gravity) to be less thus decreasing the amount of force needed to lift.
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.

How will the angle of a ramp affect the speed of a car going down it?
The larger the angle of the ramp, the faster the car will go down it.
How does the angle of a ramp affect the distance a toy car will travel?
the steeper the ramp, the farther the car goes. if your ramp is flatter, it won't go as far.

How can you measure sliding friction?
Since friction is a force, you need either a force meter or a ramp to measure it. It would be easier to measure with the force meter, but the ramp is more reliable. Method 1: Force meter. - attach a force meter to the object. - place the object on the horizontal surface you want to test. - pull the object horizontally until it moves. Keep pulling, while looking at the force meter. - the sliding friction is the average value of that force as you keep pulling. Method 2: Ramp - place your object on the ramp. the ramp should have as its surface the material you want to test. - raise 1 end of the ramp until the object begins to slide. this is the maximum angle you need. - Decrease the angle of elevation slightly. - place the object again on the ramp and nudge it. If it keeps moving, decrease the angle again. Repeat until the object is seen to stop after the nudge. - Use the equation friction = weight of the object in newtons x tangent of the angle. - repeat all steps and take an average value.
How does ramp angle affect speed?
it affects speed because it could make it go slower or faster
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.
Will mass affect a toy car going down a ramp?
yes it will ,to determine the force downward f=mgsinø where f is force in newtons, m is mass in kg, g is gravity 9.8 ms-2 , ø = is the angle from the ground. ---------------------------ø
