What noncontact forces act on an object that are balanced

Physics
1 answer:
Firlakuza [10]3 years ago
3 0

Answer:

I can give you a list of noncontact forces off of my head, if that is what you need.

Explanation:

First, gravity. It acts everywhere and pulls down every object that is in the air towards the ground, unless they have an equal and opposite force that counters it.

Second, wind. I don't think this will count because wind is a physical thing, but it can be used in the same way as we did with gravity. If the force counteracting it is larger, equal, and opposite of the force it is countering, then it will move forward, through the wind.

What three things might influence a slide when conditions are right? What types of material can make up a flow?
Diano4ka-milaya [45]
The three things that can affect a condition to enforce a slide is friction, weight, and slope of an area. Solutions that can make flow easily are those that can create less friction depending on the condition of an environment where it is present. Some of these materials are water, oil, and dense liquids.

A 2-kg object is initially at the bottom of a long 50° inclined plane, and is beginning to slide up this inclined plane. The ini
Over [174]

Answer:

Explanation:

Given

mass of object m=2 kg

inclination \theta =50^{\circ}

\mu _k=0.3

\mu _s=0.4

initial velocity u=3 m/s

acceleration of block during upward motion

a=g\sin \theta -\mu _kg\cos \theta

a=g(\sin 50-0.3\cos 50)

a=5.617 m/s^2

using relation

v^2-u^2=2a\cdot s

where s=distance\ moved

v=final\ velocity

v=0 because block stopped after moving distance s

0-(3)^2=2\cdot (-5.617)\cdot s

s=\frac{4.5}{5.617}

s=0.801

If block stopped after s m then force acting on block is

F=mg\sin \theta =friction force f_r=\mu mg\cos \theta

F>f_r therefore block will slide back down to the bottom
