Unfortunately, the answer which [I think] is required is incorrect.
I expect that the answer that you are required to provide is Newton's law of Inertia. A part of this states that a body in motion remains in constant motion in a straight line unless it is acted upon by an external force. However, there are very few place in space where this can happen. Even at points in space where the gravitational force of the Sun is exactly matched by that of the Earth, as soon as the spacecraft moves from that point, the forces will be in imbalance and the spacecraft will experience an external force which will affect its speed.

What are the forces when a spacecraft takes off?
Thrust is the force that propels a rocket or spacecraft and is measured in pounds, kilograms or Newtons.
A spring stretches 11 centimeters from its equilibrium position when an object weighing 29 newtons is hung from it. What is the spring constant?
The spring constant is 263.6363... repeating Newtons per metre.
An aircraft taxiing at a constant speed is an example of what law?
Newtons first law
What is the constant force of gravity here on earth?
9.8 newtons per kilogram of mass.
Why does more mass equal more gravity?
it doesn't...gravity on earth is constant...9.8 Newtons

When they are in orbit can a spacecraft carry on for years without firing a rocket?
newtons third law

The spring constant is 263.6363... repeating Newtons per metre.
What will the weight of a ball in water be if its weight in air is 2 newtons?
Weight in a constant gravitational field is also constant, regardless of any surroundings. The weight will be two newtons underwater as well.
What is si unit of spring constant k?
It is Newtons per metre.

How many kilo-newtons in 195kg?
195 kg of mass weighs 0.312 kilo-newtons on the moon, 0.686 kilo-newtons on Mars, 1.911 kilo-newtons on earth, and zero newtons while coasting at constant speed in space from any one of them to either other.
What theory states that heat comes from constant motion?
newtons 1 law of motion
What is the constant force of gravity here on earth?
9.8 newtons per kilogram of mass.
What is the force between the earth and a body on earth?
The gravitational constant on Earth is 10 Newtons per kg (well exactly about 9.81 Newtons)
How do you find the spring constant?
Measure how many newtons of pull you need in order to stretch the springtwo centimeters longer. Then the spring constant is1/2 of (that number of newtons) per centimeter, or50 x (that number of newtons) per meter.======================================US, Liberian, and Burmese version:Measure how many ounces of pull you need in order to stretch the springone inch longer.Then the spring constant is (that number of ounces) per inch .
