An object, experiencing no friction, keeps moving at a constant speed. What can we say about the net force on the object? a) the net force keeping the object going is the same as the force that would be required to stop it
b)the net force is in the same direction as the object's velocity
c)the object is not changing its speed but its velocity might be changing in Direction so if there is a net force it is that right angles to the velocity
d)since the object has no acceleration there is no net force
e)the net force is equal to the weight of the object ​

Explanation:

Let's look at a mathematical representation of this. The equation for tis is just a souped up version of Newton's 2nd Law:

F - f = ma. It an object is moving at a constant speed, the acceleration of that object is 0. That changes this equation to

F = f which states that the applied Force equals the frictional force, choice a.

Hello 18huntsprea 


Question: Where might water be found on the moon?

Near The Poles (C)

Reason: Water is most likely to be discovered near the poles. The South pole is the most likely one.

Hope This Helps!
