What is drag? In what situations might it act on the force of gravity?

2 answers:

7 0

Drag is passive, therefore it does not act on gravity. Drag is a mechanical resistance to motion. If the motion in question was induced by gravity drag it can impede that motion, but has no effect on the gravity.

hope this helps!

Answer:

Drag is a force of resistance that acts in fluid motion. When there is relative motion with respect to a fluid, a drag force acts in the opposite direction to the motion. Drag depends on viscosity, compressibility of the fluid and mass of the object.

When the sum of drag force and buoyant force are equal to the downward force of gravity, the object falls with a constant velocity known as terminal velocity.

Amanda [17]

Answer:

60000 J

Explanation:

Assuming the force is applied parallel to the displacement of the elephant, the work done to move it across the floor is

$W=Fd$

where

F = 2000 N is the force applied

d = 30 m is the displacement of the elephant

Substituting the numbers into the formula, we find

$W=(2000 N)(30 m)=60,000 J$

An empty beaker is placed on a top-pan balance. Some water is now poured into the beaker.What is the weight of the water? A. 0.0

mario62 [17]

Answer:

A. 0.044 kg

Explanation:

We need to subtract the sum of (beaker+water - empty beaker) which is 0.106 kg - 0.062 kg = 0.044 kg. The answer will not be written in Newton because this unit is used for force only and in this question w have to find the weight.

Hope it is enough.
