How the tension can be greater than gravity yet the elevator is moving downwards?

The extra tension depends not on the velocity of the elevator, but on its acceleration.

How do you draw an elevator free body diagram?
Draw an arrow pointing upwards for the tension force and an arrow pointing downwards for the weight of the elevator which will be its mass times gravity (mg). Also, draw another arrow pointing downwards for any mass that may be inside the elevator (another mass times gravity arrow but for a separate weight) and add that value to that of the weight of the elevator. Depending on the direction that the elevator is moving (up or down) draw another arrow respectively and label it "a" for acceleration.
What has surface tension greater than water?
Cold custard has a greater surface tension than water, Hence the reason you can run on it.
Why needle with grease float on water surface?
Surface tension. Translated that means that the attraction between the water molecules (to each other) is greater than the force (gravity) pushing the needle down.
What can be a centripetal force Friction tension gravity or all?
all of the above.. all of the above..
How do forces acting on rock cause tension?
gravity and moons forces pulls it up

What two forces act on you while you are in a moving elevator?
Gravity and tension

Gravity and tension
What forces did you recognize in the activity?
In the activity, I recognized the force of gravity acting downwards on the objects, the force of tension in the strings holding the objects, and the forces of friction between the objects and the surfaces they were placed on.
What is the magnitude of the tension in the cord?
Tension = mass(acceleration) + force of gravity Force of gravity equals mass times gravity (9.8m/s2)

Does Tension stress creates folded mountains compression stress creates fault-block mountains and the third type of mountain is volcanic?
First understand that in GEOLOGY there can be no such thing as a "tension stress". Gravity ensures that all things are in compression. The only change is in the direction of maximum stress. When gravity (downwards) is the direction of maximum stress and one or other of the horizontal stresses decays slightly, fault block mountains form. When gravity (downwards) becomes the lowest stress, reverse faults (thrusts) and fold mountains are formed. When a hydraulic fluid (magma) penetrates a rheologically solid medium this will crack the medium an rise towards the surface. If the magma contains gas this will fizz and cause a volcano.- Is the Answer True or False?-Olivia
What are the five forces that act upon bridges?
1.compression 2.tension 3.torsion 4.shear 5.gravity
What forces do you feel on a swing set?
You feel gravity and the normal force from the seat of the swing which is applying a force due to the tension from the chains of the actual swing. The tension and normal force is greater than your weight which is why u don't go through the seat and break it. Since u are going in a circular fashion when u swing u also feel centripetal force which is due to the tension of the swing overpowering gravity and keeping u swinging.
Why needle with grease float on water surface?
Surface tension. Translated that means that the attraction between the water molecules (to each other) is greater than the force (gravity) pushing the needle down.
What happens if droplets of condensation become to big?
The force of gravity from the growing mass of the droplet will overcome the force of tension between the droplet and the surface the water tension is "holding" it to. Once gravity is larger than tension, the droplet falls to the ground.
What causes a pendulum to continue swinging?
Gravity and the tension in the string.
