Lifting a person into the air requires a force greater than their weight, which is determined by their mass and the acceleration due to gravity (approximately 9.81 m/s²). This can be achieved through physical strength, such as lifting by hand or using equipment like a hoist, or by utilizing mechanical means, such as an aircraft or a drone. Additionally, factors like balance, stability, and safety measures must be considered to ensure a safe lift.

How many flies does it take to lift a person?
About 3.
What If You are pregnant and take care of an elderly person Is it safe to lift and how much?
No it is not safe to lift heavy weights when pregnant especially not another grown up person. All the best to you!
How much hot air does it take to lift 30 lbs?
To lift 30 lbs, you would need approximately 13.6 cubic feet of hot air. This calculation is based on the fact that hot air balloon systems typically require about 2 cubic feet of hot air to lift 1 lb of weight.
What properties of air affect lift?
The properties of air that affect lift include its density (less dense air generates more lift), temperature (warmer air is less dense and can affect lift), pressure (lower pressure can decrease lift), and humidity (moist air is less dense and can reduce lift).
What to do when the person you like is not giving lift to you?
Take the hint and direct your attention to someone else.
Can air hold a person up?
No, air on its own cannot hold a person up. The lift required to overcome gravity and support a person's weight typically comes from other sources such as buoyancy (in the case of balloons or aircraft) or lift generated by wings (in the case of airplanes).
How much hot air does it take to raise a hot air balloon?
It typically takes around 65,000 cubic feet of heated air to lift a hot air balloon, depending on its size and weight. The burner heats up the air inside the balloon, causing it to become less dense than the air outside the balloon, which creates lift.
Does it take more than one person to operate a car lift?
Yes one person can physically operate a car lift as it works simply on hydraulics. However it is essential to have a second person present in the preparation for using a lift to guide the car onto the lift ramps successfully and for safety's sake having a second person present while you are working under the ramp. But in essence it is physically possible to operate a lift with one person, just not advisable.
What keeps a plane in the air?
Lift keeps an airplane in the air because drag is a counteract. Drag is what makes the plane crash. To have to much drag you need something like a flap pointing toward the front of the plane. If you take off the flap, you have more lift. Plane wings are tilted upward so that whenyou take off, the air is pushing the most downward part up, therefore causing lift, keeping the plane in the air.
How do airplanes take flight?
They increase speed until the wings gain 'lift' from the air flowing over them.
How much force is needed to lift 78 pounds person into the air?
To lift a 78 pound person into the air with a constant velocity, you would need to exert a force equal to 78 pounds (the weight of the person) in the upward direction. This force is required to counteract the force of gravity acting on the person.
How do you help an elderly person get up from a chair?
You take their arms and elbows and help lift them to their feet.
