Why do you have to use force to lift objects?
To lift objects, you have to overcome the force of gravity acting on them. By applying an upward force greater than the force of gravity, you are able to lift the object against gravity's pull. This force is necessary to provide the object with the acceleration needed to move it upwards.
What is the greater mass of an object is the force of lift?
If the mass of an object is greater than the force of lift, the object will not be able to overcome gravity and will not be able to lift off the ground. It is important for the force of lift to be greater than or equal to the mass of the object for it to be able to achieve lift.
What vehicle can overcome earth's gravity because it expels a gas with a force equal to the pull of gravity?
That sounds like a "hovercraft", which doesn't rise or fall, but just exactly hangs there.If the vehicle expels a gas with a force GREATER than the pull of gravity ... like a rocket for example ...then it can actually rise.
If gravity pulls things down how come plans fly and not get puuled down?
Planes are able to fly because they generate lift by moving air over their wings through propulsion from engines. This lift force counteracts the force of gravity, allowing the plane to overcome the downward pull and stay in the air.
How are magnets rated in terms of their strength and performance?
Magnets are rated based on their magnetic field strength, which is measured in units called gauss or tesla. The higher the gauss or tesla rating, the stronger the magnet's performance. Magnets with higher ratings are able to attract or repel objects with greater force.

When an object is less dense than the liquid is in and is able to overcome the force of gravity?
Technically, nothing other than a rocket, or plane, or any flying vehicle, can overcome the force of gravity. Liquids and solids, have weight which gravity pulls down. Only gas will rise as the particles are too far from each other to create any form or liquid or solid, therefore it has no weight.

What forms interstellar gases condense due to gravity?
Any type of gas can do that. The only condition is that there be a sufficient amount of gas - otherwise, the gravity won't be able to overcome the pressure of the gas.
How are magnets attracted to another?
Magnets have both a north pole and a south pole. One of the laws of magnets is "like forces repel, unlike forces attract." So, if you bring the north pole of one magnet towards the south pole of another, there will be a strong attractive force between them. With very strong magnets, you may not be able to force two north poles together - they will just slide away.
What force makes the coilgun work?
the force of objects being attracted by magnets. the coils or solenoids act as magnets and the projectile (which must be able to attract to magnets, often iron or steel is used) is attracted to the coils. but when the projectile reaches the coil the coil must be turned off so the projectile keeps going instead of stopping at the coil.
How are magnets the same?
Magnets are able to attract magnetic objects.
How are magnets rated in terms of their strength and performance?
Magnets are rated based on their magnetic field strength, which is measured in units called gauss or tesla. The higher the gauss or tesla rating, the stronger the magnet's performance. Magnets with higher ratings are able to attract or repel objects with greater force.
What force pulls a tractor back?
friction and gravity , gravity keeps the tractor down so you can even be able to touch it . frictionhelps objects glide , be pushed
Why does gravity my pencil not let my fly into the air?
Gravity is a force of attraction that pulls objects toward each other based on their mass. In this case, the Earth's gravity is pulling your pencil towards the ground, preventing it from floating in the air. The force of gravity is much stronger than any force you could exert to make the pencil fly upwards.
