To overcome gravity, an object must generate lift equal to or greater than its weight. This means that the lift force must be at least equal to the gravitational force acting on the object, which is calculated using the formula ( F = m \cdot g ), where ( F ) is the weight, ( m ) is the mass, and ( g ) is the acceleration due to gravity (approximately 9.81 m/s² on Earth). For example, if an object weighs 1000 N, it would need at least 1000 N of lift to ascend.
What else can I help you with?
Why does an airplane need more lift then weight?
Obviously so it can overcome gravity and take off.
Why are magnets able to overcome force of gravity?
You don't specifically need a magnet to overcome the force of gravity; ANY force that is stronger than gravity can "overcome" it, at least temporarily. For example, if you lift an object up, you are "overcoming" the force of gravity.
What are two forces that planes need to overcome in order to fly?
Planes need to overcome both gravity, which tries to bring them down, and drag, which is the resistance caused by the air they are moving through. By generating lift through their wings and thrust through their engines, planes can overcome these forces and achieve flight.
What does a spacecraft need to overcome?
it needs to overcome the gravity of the earth lol
How much force is needed to lift a 45 kg mass?
To lift a 45 kg mass, you would need to apply a force equal to the gravitational force acting on the mass, which is approximately 441 Newtons (45 kg * 9.81 m/s^2). This force would need to be greater than the weight of the mass to overcome gravity and lift the object upward.
How do you go against gravity?
To go against gravity, you need a force stronger than gravity pulling you upwards. This could be achieved by using a propulsion system like a rocket or thrusters. Alternatively, you could also use lift generated by wings, rotors, or engines to overcome the force of gravity.
Would it be easier to lift a truck on the moon or on the earth?
It would be easier to lift a truck on the moon because the moon has weaker gravity compared to Earth, approximately 1/6th of Earth's gravity. This means you would need to exert less force to lift the same truck on the moon than on Earth.
How do you make an elephant fly in halo 3 with a hornet?
You cant do it with a hornet you need a gravity lift and 2 drop pods put the gravity lift by the moniter so its under the roof sort of thing. Then put the drop pods on the gravity lift then it will fly !! Have fun
What kind of force is needed to launch rocket ships?
Rocket ships are launched by a combination of forces, including the thrust generated by the rocket engines and the force needed to overcome gravity. The thrust from the rocket engines propels the rocket forward, while the force needed to overcome gravity allows the rocket to lift off the ground and enter into space.
Why can you not lift a bucket of water without holding it?
You cannot lift a bucket of water without holding it because you need to apply a force to overcome the weight of the bucket and the water inside it. If you do not hold it, the force of gravity will cause it to fall back down. Holding the bucket allows you to apply the necessary force to lift it.
What forces need to be overcome to get to the moon?
If you want to get out of the earth, say for example you want to get to the moon, then you will need to escape gravity.
How much force will be required to lift a weight if it weighs 300 pounds?
If the weight is 300 pounds, you will need to apply a force of at least 300 pounds to lift it against the force of gravity. This force is known as the weight of the object.
