What are some facts about gravity?
Gravity is a force on earth that pull everything down. On the moon there is less gravity than on the earth
Is it true molten material in the asthenosphere rises in convection currents because heated materials become more dense?
Actually, hot, less dense material rises, and cold, denser material sinks. Denser material will be heavier (per unit volume) and gravity therefore pulls it down. Less dense material has buoyancy and rises. It's very logical.
A horizontal force acts a body that is free to move can it produce an acceleration if the force is less then the weight of that body?
Yes it can, and if less force is needed if you eliminate the possibility of friction. You can find many examples of this, but i think this is an excellent opportunity to devise an experiment and practice your scientific methods.
How could a toy rocket accelerate after takeoff?
As long as the thrust is more than the weight of the rocket (toy or otherwise) the rocket will accelerate. When the thrust matches the weight, the rocket will cruise. When the thrust is less then the rocket will slow.
How does a rocket work with refrence to Newton's laws of motion?
It works quite well. Here's how. 1. The rocket won't move until the engines are fired. That's the law of inertia. It's at rest, and it remains at rest until it's acted upon by an outside force. The opposite is true, too. If a body is in motion, it wants to remain in motion unless it's acted on by an outside force. 2. When the rocket motors are fired, the rocket takes off. It accelerates, and that's the law of acceleration. Force = mass x acceleration. The more mass it has for a given thrust, the less acceleration it has. The more thrust it has for a given mass, the more it accelerates. 3. The rocket motors inject hydrogen and oxygen (typical NASA "big rocket" fuel) into the throat of the motor where it burns quickly and hotly. Superheated combusted gas is rushing out the exhaust nozzle with tremendous force, and an opposite force is generated. That opposite force causes the rocket to be accelerated up (since the nozzles are pointed down). For each reaction there is an equal and opposite reaction, Newton's third law. Need a link? You got one to our friends at Wikipedia, where knowledge is free.
How does the force change on how high the rocket goes?
At high elevations, the force of gravity becomes less.
Why is it easier for a rocket to take off from the moon?
Gravity is weaker because the moon has less mass.
How is acceleration affected when a rocket travels higher?
It starts with the equation a=F/m. As fuel is burned, the mass of the rocket becomes less. As "m" decreases as "F" remains the same, "a" increases. There is less mass to be accelerated as fuel is consumed. There is also less external force acting upon the rocket (No major gravity or air resistance). As Newton's first law states that an object will continue moving at the same velocity until an external force acts upon it. It would be easier to accelerate because the rocket doesn't require much fuel to generate force in space (there's no force acting upon it in the first palce)
Would the force of of gravity on ganymede be more or less than the gravity on the moon?
less
What happens to the force of gravity of the distance increases?
At greater distances, the force of gravity becomes less.
Which force gives you weight?
The force of gravity. The gravity on the moon is less than on earth, and if you weighed yourself on the moon, you would weigh less.
Would a rocket leaving the moon surface require as great a speed or force as one leaving the earth surface?
No. There is less gravity on the moon, therefore the rocket would feel less of a pull towards it than the earth. It would be easier to leave the moon than the earth.
Why does it require less fuel to accelerate a rocket in outer space than in Earth's atmosphere?
Because there's less gravity therefore it takes less effort to push the rocket
Does steam resist gravity?
only in as much as whatever kinetic energy it has, or if it is less dense than the surrounding atmosphere. nothing really "resists" gravity, but it can work counter to it's force. steam rises not because it is resisting gravity, but because it is less dense than the air surrounding it, therefore causing it to be "pushed up"
Do less massive planets have less gravitational force?
Gravity is the pull from matter. Less matter means less gravity, so yes.
Is your weight your mass or force?
Your weight is a combination of your mass and the force of gravity. on the moon your weight is less because the force of gravity is less, however your mass remains constant no matter where it is measured.
How high would a rocket go on the moon compared to earth?
If a rocket is launched from the moon it will travel faster and longer, as it has less gravity.
