What else can I help you with?
Is there friction when a toy car rolls down a ramp?
Yes Friction between the wheels and the ramp and also friction between the body of the car and the air (unless the car and ramp are in a perfect vacuum) There will be additional friction in the bearings or ball race of the wheel / axle too
How does the speed of a ball change with the different ramp surfaces?
It depends on the ramp surfaces because some ramp surfaces have less friction than others and some have more friction than others.
Is a crate resting on a loading ramp an example of static friction or fluid friction?
me
How far can a toy car go on a ramp?
The distance a toy car can travel on a ramp depends on factors like the incline of the ramp, the initial velocity of the car, and any friction present. In general, a toy car on a ramp can roll for a distance equivalent to the length of the ramp if there is no significant friction or obstacles in its path.
A block of wood is at rest on a wooden ramp. When wheels are attached to the block of wood it moves down the ramp. Explain each situation in terms of friction.?
In the first situation without wheels, the block of wood is at rest due to static friction between the wood surfaces of the block and the ramp, which resists motion. When wheels are attached, rolling friction replaces static friction, allowing the block to move more easily down the ramp since rolling friction is typically lower than static friction.
Is the ideal mechanical advantage of the ramp is it's mechanical advantage with friction?
No, the ideal is without friction.
The Ramp controller is responsible for what?
A ramp controller is responsible for the loading/unloading sequence of passenger and cargo aircraft on the tarmac (ramp). I was a ramp controller when I was in the Air Force and worked as an Air Freight/Air Transportation Supervisor.
What terms of friction would I use to describe a block of wood when it is at rest on a wooden ramp then when I add wheels to the block of wood to make it go down the ramp?
at rest it is static friction while on wheels it is rolling friction
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 does friction affect the mechanical advantage of a simple machine?
friction opposes the mechanical advantage of a simple machine. for example, if you had a inclined plane that gave you an advantage of 3:1 (3 times longer then it is high) the frictional force cause by an object being pushed up the ramp would be in the direction opposite to the direction of motion equal to u*N (mu times the normal force of the object) so for a 10 kg object being pushed up the ramp, under normal gravity = 9.81 N and a coefficent of friction = .3, the frictional force would be equal to 3 N. if you were pushing the object on flat ground with a force of 15N, you would actually need 18 N to maintain the same speed of having no friction appling this to the ramp, if 15N is needed to push on flat ground, only 5 N would be needed to push the object up a 0 friction ramp, and 8 N would be needed to push it up a ramp with friction to maintain the same speed. this is true for all simple machines, and it only depends on where the friction is being created, weather it be friction between a screw and wood, a rope and the pulley, or the fulcrum and a lever

If you grease a ramp to make a box slide more easily the ramp and mechanical advantage increases because has been reduced.?
Greasing a ramp reduces friction between the ramp and the box, making it easier for the box to slide. This reduction in friction increases the mechanical advantage of the system, allowing the box to move with less effort.
