How is the force of earths gravity overcome when an object is launched into space?
When on Earth, you can escape if you move away from the Earth at the "escape" speed. Gravity will slow you down and you will reach zero speed at an infinite distance.
What speed does the space shuttle have to reach to escape earths gravity?
17,500 miles per hour puts the shuttle in orbit. BUT the gravity is still there. I'm fact there is about 90% of the gravity while the shuttle is on the ground. That great rate of speed is required to keep the shuttle from falling back to earth. At that speed the shuttle is basically falling around the planet.
An engine with a speed that can escape earth's gravity?
space probe
Why must a spacecraft reach escape velocity to be able to go to space?
A rocket needs to travel at 7 miles-per-second or about 25,000-miles-per-hour to leave the pull of earth's gravitational force, and reach outer space. This speed is known as escape velocity.
How does gravity effect earths rotation and revolution?
The Earth's rotation on its axis is not directly affected by gravity except that gravity holds Earth together as a sphere.Earth's revolution round the Sun is an "orbit" which obeys the laws of gravity.There is also a slight transfer of the rotational energy of the Sun to Earth's revolution speed. The Sun's spin is slowing and Earth is moving away form the Sun a little. {Note, this effect is far more pronounced between the Earth and the Moon].
What is the speed necessary to escape the earths gravity?
The speed at which a rocket must travel to escape the gravitational pull of the earth is 25,000 miles per hour.
What is the earth greatest speed of earths rotation?
The speed of rotation is greatest at the equator; 1038 miles per hour.
Did the recent earthquake in japan speed up the earths rotation?
No.
What is escape volocity?
Escape velocity is the speed you would have to go to escape gravity.
What is Rocket speed per sec to escape from earth gravity?
the rocket speed required to escape out of the earth's gravity is known as escape velocity which is numerically equal to 11.2 km per sec.

To escape from a planets gravity an object must reach a speed called the?
Escape Velocity
An engine with a speed that can escape earth's gravity?
space probe
Why you must study escape velocity?
You don't. "Escape velocity" is a meaningless number. "Escape velocity" is the speed at which a CANNON SHELL must be fired in order to escape from the Earth's gravity well. With a powered rocket, you can "escape" from the Earth's gravity at ANY speed - as long as you have enough fuel.
In order to escape the gravity of earth a space vehicle near earth must have a speed of about?
about 25,000 mph to completely escape earth's gravity
Why does escape speed decrease with altitude?
I think it's because of gravity.
