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 if your mass is 75kg. You stand on a scale in an elevator that is about to go down. Starting from rest the elevator accelerates at 2.0ms squared for 2.0s then travels at a constant speed. What do?
While the elevator accelerates downward, you will experience a greater force than your actual weight, resulting in a higher reading on the scale. Once the elevator reaches a constant speed, the scale will show your actual weight, as the net force on you is then equal to your weight.
Zach whose mass is 80 kg is in an elevator descending at 10 ms the elevator takes 3 s to brake to a stop at the first floor?
The force required to stop the elevator can be calculated using the equation F = m*a, where m is the mass of the person (80 kg) + mass of the elevator and a is the acceleration of the elevator (which is the velocity change divided by time). Once the force is calculated, it can be converted to the braking force needed by dividing it by 2, as each braked object resists the deceleration force equally.
When your mass increases what happens to your weight?
If your mass increases, your weight also increases.
Do things weigh more when moving in elevators?
Yes objects do weigh more whilst moving in elevators. This is due to energy mass equivalence that Einstein detailed through the well-known e=mc2 equation. An object in an elevator is moving and therefore has kinetic energy, which translates into more mass. This increase, however, is extremely minute and not measureable with normal scales (even down to .000001 of a pound) because the mass increase is the amount of energy divided by 8.98755179 × 1016 (the speed of light squared).
What happens to mass when density decreases?
The density goes down.
What heppens to density when mass goes down?
The density goes down.
What happen to gravitational pull of Earth if mass of the object increase or decrease?
The FORCE, or Gravitational Pull of the Earth on an Object is DIRECTLY PROPORTIONAL to the Object's Mass. Force = Mass x Acceleration of Gravity So, if Mass goes up, Pull goes up, If the Mass goes down, the Pull goes down.

What happens to the atomic mass as you go from down a group in the periodic table and why?
The atomic mass generally increases as you go down a group in the periodic table. This is because as you move down a group, the number of protons and neutrons in the nucleus of the atoms increase with the addition of more energy levels or electron shells.
What type of erosion includes relatively rapid mass movements of soil from high elevation to low elevation?
when you press up or down a piston will move the elevator up or down
How does gravity affect the weight of matter?
It's a very direct relationship; weight is caused by gravity. weight = mass x gravity Therefor, if gravity goes up and mass stays constant weight, goes up. And the reverse is true if gravity goes down and mass stays constant, weight goes down.
What happens when warm air mass goes over a cold won what is the condition?
It would be a windstorm
How a liquid changes to become a solid?
As temperature goes up density goes down. As volume goes up density goes down. As mass goes up (or increases) density also increases, or in other words, it freezes.
What is the new element formed after the alpha decay occurred?
AlphaThe atomic number goes down by two and the atomic mass number goes down by four.Beta-The atomic number goes up by one and the atomic mass number stays the same.Beta+The atomic number goes down by one and the atomic mass number stays the same.
What is formulae for elevator's counter weight calculation?
The mass must be greater than the mass of the elevator including the maximum amount of cabling that it has, plus the carrying capacity plus a safety margin.
