Why does space probe need very little fuel?
In space there is no friction, so once the space craft gets moving it will stay in motion until it runs into something. The lack or resistance (friction) means it doesn't have to keep pushing to continue moving. It only needs enough fuel to get it up to speed then it will continue on by itself.
What is angle period of satellite?
The angle of the satellite period, depends on where the satellite is positioned. When you figure out where the satellite is you position the angle to be where and what you need.
Why do engineers need to keep the mass of a spacecraft as low as possible?
The heavier it is the stronger the engine has to be. And the stronger the engine the more fuel will it burn. And the more fuel it burns the more fuel has to be carried in the rocket. And the more fuel the rocket has to lift the stronger the engine has to be.
How much fuel will be needed in a rocket?
How much fuel will be needed in a rocket will depend on the size of the rocket and where it is going. A rocket that will be traveling into space burns a lot of fuel and will need enough to keep it in orbit for teh desired time.
Why are old satellites brought back from space?
Unless they are especially valuable or designed to be returned, they aren't "brought back". They simply fall back as their orbit slows relative to the earth due to drag from gravity, magnetic fields, dust and gas. To keep a satellite in orbit permanently it would have to be moved up periodically (some can do this on their own). Sometimes satellites run out of the fuel they need to have their orbits adjusted to keep them in the right place. Geostationary satellites need to be moved every two weeks.
Why doesn't a satellite need fuel to keep moving?
A satellite needs fuel to keep moving because when it's in space there is no air resistance and the gravitational pull and friction won't effect it.
Why do cars need to be lightweight or weigh less?
Heavy cars are not economical. Lightweight cars use less fuel to get them moving and keep them moving.
Why is urbanization good?
Urbanization can lead to economic growth, innovation, and increased access to services such as healthcare and education. It also promotes cultural exchange and diversity, as people from different backgrounds come together in cities. Additionally, urban areas tend to be more environmentally efficient compared to rural areas in terms of resource use and emissions per person.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
Is moving around better when you have the flu?
You need to keep warm and stay indoors not moving around.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.

What does the body need to keep the food moving through the body?
liquid
Why the satellite dish doesn't need moving once it's set up?
Because it has established a firm connection with the Alien base on the moon.
The group that captured Rowlandson is forced to keep moving because of its .?
need for food
What machine reduces the force you need to apply to a bicycle to keep it moving?
The lever.
Why does a car need a forwards force to keep moving?
Resistance from air and friction.
