How do you calculate the force of an elevator?

The normal force is equal to your apparent weight….Consider the normal force acting on you from the elevator:

1. N = mg if the elevator is at rest or moving at constant velocity.
2. N = mg + ma if the elevator has an upward acceleration.
3. N = mg – ma if the elevator has a downward acceleration.

What is the tension in the elevator cable causes the elevator to rise?

An elevator is a box that moves up and down a building with the help of strong cables. The tension in the cables enables the elevator to move heavy weights upward and downward. The counterweights provide tension for the cables to hold the elevator. The entire movement is controlled by intelligent electronic systems.

What is the tension in the cable that supports the elevator?

To keep the elevator from accelerating upward or downward (basically to keep it at a constant velocity), the tension force MUST be equal to the force of gravity of the elevator. In essence, the cable is providing an upward acceleration of 9.8 m/s2 to balance out the downward acceleration of gravity.

Would you weigh less in an elevator that moves downward at constant velocity?

At constant velocity, acceleration is zero. Therefore,there is no change in weight. When the lift accelerates downwards at 9.8m/s^2,the person(astronaut) experiences weightlessness. if the elevator is moving with a constant velocity (in whichever direction), the weight will not change.

How do you find tension with upward acceleration?

What is the acceleration of the elevator and the person inside of it if the cable of the elevator breaks?

You Feel “Weightless” If the Elevator Cable Breaks Different sensations of apparent weight can occur on an elevator since it is capable of zero or constant speed (zero acceleration) and can accelerate either upward or downward. If the elevator cable breaks then both you and the elevator are in free fall.

Is the acceleration of the elevator upward downward or zero?

We have to find the acceleration of an elevator is upward, downward or zero. Thus, Since, Hence, the acceleration is upward.

When a lift is accelerating downwards?

So, when a lift accelerates upwards, the apparent weight of the person inside it increases. So, when a lift accelerates downwards, the apparent weight of the person inside it decreases. R = m(g – g) = 0. Thus, the apparent weight of the man becomes zero.

What is tension equation?

Tension formula is articulated as. T=mg+ma. Where, T= tension (N or kg-m/s2) g = acceleration due to gravity (9.8 m/s2)

How do you calculate the force acting on an elevator?

The combined system of you + elevator has two forces, a combined force of gravity and the tension in the cable. Consider the normal force acting on you from the elevator: N = mg if the elevator is at rest or moving at constant velocity. N = mg + ma if the elevator has an upward acceleration.

What is the acceleration of an elevator when it slows down?

IF the elevator is going up, and the apparent acceleration in the cab is less than 9.8 m/s/s, then the elevator is at that moment slowing down. If an object is being pulled up at a constant velocity, then there is zero acceleration because forces are balanced (specifically, the tension in the cable balances the weight).

What is the elevator problem in physics?

Elevator Problem. Elevator Problem. This is an application of Newton’s second lawto the forces felt in an elevator. If you are accelerating upward you feel heavier, and if you are accelerating downward you feel lighter.

What would happen if the elevator cable broke in the elevator?

If you are accelerating upward you feel heavier, and if you are accelerating downward you feel lighter. If the elevator cable broke, you would feel weightless since both you and the elevator would be accelerating downward at the same rate.
