Which of newtons laws is in control of a spacecraft cruising through space at constant speed without using any fuel?
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?
When a spacecraft takes off, the main forces involved are thrust and gravity. Thrust is generated by the spacecraft's engines pushing it upwards, while gravity pulls the spacecraft back toward Earth. Other forces, such as aerodynamic drag and lift, may also be present depending on the specific design of the spacecraft.
How does newtons law and inertia in space?
Newton's first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. In space, where there is very little friction or air resistance, objects will continue moving in a straight line at a constant velocity once set in motion, exhibiting inertia. This is why spacecraft can maintain their trajectory once launched and do not require constant propulsion to keep moving.
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 calculated by dividing the weight of the object (29 N) by the distance it stretches the spring (11 cm). First, convert 11 cm to meters by dividing by 100 (0.11 m), then divide the weight by the stretch distance to get the spring constant: 29 N / 0.11 m = 263.6 N/m.
What are the units for the constant k in physics?
The units for the constant k in physics depend on the specific equation it is used in. Some common units for the constant k include N/m (newtons per meter) for spring constants and J/molK (joules per mole per kelvin) for Boltzmann's constant.
What is the difference in 200 newtons and 20 newtons?
The difference between 200 newtons and 20 newtons is 180 newtons.
When they are in orbit can a spacecraft carry on for years without firing a rocket?
newtons third law
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

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 .
What are the units of the Coulomb constant k which appears in Coulomb's law?
newtons * meters squared / coulombs squared
How is mass and acceleration related if force is constant?
Both mass and acceleration will remain constant but speed will increase. Its explained in Newtons second law, in short: F=m*a
What does pressure times volume equal?
As pressure is force per unit area (Newtons/m2) and volume is m3, then PV would simplify to Newtons*meters which is joules.

What is Isaac Newtons theory called?
Well he fundamentally proposed a few theories. But he is eminently known for introducing the 'Mathematical Principles of Natural Philosophy'. These principles include Newtons 3 laws of motion and his Gravitational Constant. If you want to know what they are, google, Newtons 3 laws. He was quite smart!
