If an object is sliding down a frictionless ramp will the force on the object by the ramp just be 0?
or will it be equal to the normal force?
Thanks

Thre will be no force by the ramp on the object along the incline, but perpendicular to the incline, yes, the ramp will exert a normal force on it.mybrohshi5 said:If an object is sliding down a frictionless ramp will the force on the object by the ramp just be 0?

The normal force of the block on the hamster would be equal and opposite to the normal force of the hamster on the block, per Newton's 3rd law... It's magnitude must be determined using trig and one of the other of Newton's laws.mybrohshi5 said:So for this case...

While the hamster is sliding down, what is the magnitude of the force on the hamster by the block? The block is frictionless.
would it just be the normal force of the hamster which is perpendicular to the block?
Jebus_Chris said:Only part of the hamster's weight is measured on the scale. Part is directed down the ramp which doesn't measure on the scale but the other part pushes the ramp down and is measured on the scale.
The block weight and parallel comp of the hamster act in different directions, so adding them together doesn't give you anything at all to work with.. You should be adding the block weight and the vert comp of the Normal force between the hamster and ramp to solve for the scale reading.. The key is to find the vert comp of the normal force betwen the ramp and hamster. The hamster is accelerating in the y direction, so you must use Newton 2 when looking at the forces acting on the hamster in the y direction. It's a bit of trig involved,and a bit tricky.mybrohshi5 said:so the answer ended up being 9.47
Im not sure how its exactly that because i got 9.6 for my answer.
i added the weight of the block plus the component force of the hamster that is parallel to the slope of the ramp so
9.8(.82) + (.25)(9.8)sin(40) = 9.6
anyone know why its 9.47
did i do it right and the online homework just rounded differently or something like it usually does?
thanks
The steeper the angle of the ramp, the faster an object will slide down due to the force of gravity pulling it downwards.
Yes, the material of the ramp can affect the speed of sliding. A smoother surface will result in less friction and a faster slide, while a rougher surface will create more friction and a slower slide.
The weight of an object affects its acceleration down the ramp. The heavier the object, the more force of gravity it will experience, resulting in a faster slide. However, air resistance may also play a role in the overall speed.
Yes, the longer the ramp, the more time an object has to accelerate and gain speed. However, other factors such as angle and material can also affect the speed, so the length of the ramp alone may not determine the speed of sliding.
Yes, there is a maximum speed an object can reach while sliding down a ramp. This is due to air resistance and other factors that can balance out the force of gravity. The exact maximum speed will depend on the specific conditions and variables of the ramp and object.
