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 does a spacecraft need to overcome?
it needs to overcome the gravity of the earth lol
Why do the aircraft need a force from their engines to fly at a steady speed?
To overcome drag. The four forces always acting on an airplane in flight are: Lift, thrust, gravity, and drag.
What are two forces that planes need to overcome in order to fly?
Gravity and aerodynamic resistance.
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 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.
When traveling uphill with the driver need to use high gears to overcome the pull of gravity?
True
Why does a rocket need a large thrust on take off from the earth?
The rocket has to overcome the pull of gravity.
Why does rocket taking off from the earth needs much more fuel than the same rocket taking off from the moon?
dunno and it need answer gravity is very strong on earth as the rocket gets higher gravity gets weaker they have to overpower gravity to lift of
Why does a shuttle need thrust?
To lift off the earth against the force of gravity. To go up.
Why moment of inertia is important in weight lifting machines?
Because you need to overcome inertia before you can lift anything
