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 gravity affect the balanced and unbalanced force?
gravity is definitely a balanced force
How does the force change on how high the rocket goes?
At high elevations, the force of gravity becomes less.
When a rocket lifts off the ground the net force is in an upward direction. Is the upward pushing force greater or less than the downward pull of gravity?
The upward pushing force is greater than the downward pull of gravity in order for the rocket to lift off the ground. This excess force allows the rocket to overcome the force of gravity and accelerate upwards.
Why is it easier for a rocket to take off from the moon?
Gravity is weaker because the moon has less mass.
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.
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 a rocket leaving the moon surface require as great a speed or force as one leaving the earth surface?
No, a rocket leaving the moon's surface would not require as great a speed or force as one leaving the Earth's surface. This is because the moon has lower gravity than Earth, so the escape velocity required to overcome gravity and leave the moon is lower than that required to leave Earth.
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"
The moon has no gravity but the rocket lands on it How?
The moon does have gravity, just less than Earth's. When a rocket lands on the moon, it is pulled towards the moon's surface by its gravity, similar to how objects are pulled towards Earth. The rocket's engines are used to slow down its descent and land safely on the moon's surface.
Do less massive planets have less gravitational force?
Gravity is the pull from matter. Less matter means less gravity, so yes.
Why does a rocket need a large thrust on take off from the earth?
A rocket needs a large thrust on takeoff from Earth to overcome the force of gravity pulling it down. The large thrust is necessary to generate enough speed to reach escape velocity and break free from Earth's gravitational pull. Once the rocket is in space, it needs less thrust to maintain its course.
