normal reaction force/slope question?

Question

If two identical objects slide down slopes of different steepness, will their normal reaction force still be equal?

Answer 1

No, the normal force will vary by the angle of the slope by the cosine.

where N=m*g*cos(a)
where a is the angle of the slope with respect to horizontal.

Answer 2

No. The normal reaction force is the component of the object's weight that the slope supports.

(Yes, it equals mgcos a, where m = mass of object in kilograms; g = 9.8 to convert your mass unit on earth to its weight force in newtons; and a = the acute angle the slope makes with the horizontal.)

As angle a gets closer to a rt angle, the slope supports less and less of the object's weight; i.e. the object is supported less and less by the slope. At perpendicular the object's weight is no longer supported by the slope, and all the object's weight is directed parallel to the slope; your normal reactive force would be zero.

Answer 3

No, they are not. The Normal force will depend on the angle of the steepness.

Answer 4

helpful sweetie a particularly extensively used reaction for a 14 3 hundred and sixty 5 days previous. what isn't is people who're now no longer virgins and for those fool boys to be rude adequate to ask you. Be proud which you are the form you ensue to be and don't enable each guy or woman mock you into dropping what's yours ie your virginity. in case you'll be able to pluck up the braveness - the subsequent time, you'll be able to declare decrease back: do you recognize it is illegitimate to ask a woman of my age that with the intention to have intercourse with them? i'm getting exhilaration from you very lots for now no longer being in a hurry to lose this efficient present day you have.

Answer 5

no because normal reaction depends on the angle of the slope.normal reaction is directly proportional to tan theta(-), where theta is the value of the slope in degrees.
