How strong is one newton in force when exerted from a rocket?
One newton of force exerted from a rocket is equivalent to the amount of force needed to accelerate a mass of one kilogram by one meter per second squared. It is a small force relative to the forces produced by rockets required for space travel.
What determines the magnitude of the normal force?
The normal force if the force of one object holding up anothe. Ex. a block of wood on the ground. The normal force is the force applied to the wood to prevent it from sinking. In other words, it is the objects weight. W=mg, where W=weight, m=mass, g=force of gravity.
When an object is said to be heavy what are the two things being considered?
When an object is said to be heavy, two things being considered are its mass and the force of gravity acting on it. The mass of an object is the amount of matter it contains, while the force of gravity pulling it towards the Earth's center contributes to its weight.
What conditions must be met for work to be done?
1. A force is needed 2. The point of application of the force is to be displaced. 3. If the displacement is in the direction of the force then work is said to be done by the force and if the direction of displacement is opposite to the force then work is done against the force.
How does the weight of a body vary with its position on earth?
Weight is measure of the product between the body's mass and acceleration due to gravity acting on it. This acceleration due to gravity is different at different locations on earth. And hence is the weight. Poles are said to have higher acceleration of gravity.
A locomotive has broken through the wall of a train station As it did what can be said about the force exerted by the locomotive on the wall Does the wall exert greater eqaul or less force than train?
The force exerted by the locomotive on the wall would be equal and opposite to the force exerted by the wall on the locomotive, according to Newton's third law of motion. The wall exerts an equal force back on the train to cause it to come to a stop.

Example of Balanced Force?
A body is hanging. The forces on it are well balanced. The weight of the body is the force acting downward and the tension in the string acting upward.Same way a body placed on a tableAdd: One example is a book sitting on a table. The book does not move because the gravitational force acting on it in a downward direction is equal but opposite to the upward normal force that the table exerts on the book.The same can be said for a person standing still on a floor. She doesn't move because the downward gravitational force acting on her is equal but opposite to the upward normal force exerted on her by the floor.

What is the magnitude of the buoyant force?
the simplest and the easiest method to find buoyant force is ................ just take a mug and dip it down to the bottom and now u will exert a vertically upward force this force is buoyant force. ---------------------------------------------------------------------------------------------- When you have a body immersed in a liquid, the buoyant force the body will experience is equal to the weight of the liquid displaced by the body which in place is equal to the volume of the body times the specific weight of the liquid. If the body floats on the surface of the liquid, the buoyant force equals the weight of the body and is equal to the weight of the liquid displaced by the body. That's why when it is said that a given ship "displaces 500 tons" it means the ship weights 500 tons which at the same time is the weight of sea water the ship's hull displaces (when in sea water).
Why is weight of an object almost zero?
The weight of an object can be almost zero in space or during free fall because weight is the force of gravity acting on an object's mass. In the absence of gravity or when experiencing weightlessness, objects do not feel the gravitational force, resulting in a weight close to zero.
If you add together all of the forces exerted on an object and get a non-zero value this is called?
This is called a net force. The net force is the combined effect of all forces acting on an object, and it determines the object's acceleration according to Newton's second law of motion.
Is pushing a box until it moves a balanced or unbalanced force?
This is unbalanced force. Whenever a greater force is acting upon a smaller force, it is clearly unbalanced. I'm pretty sure this is the right answer because if you have the same science questions from a science textbook then my science teacher said it was unbalanced.
Will magnets have pulling capacity?
magnets have potential energies associated with them and whatever object they are interacting with (must have charge to interact...). this energy does work as the force is exerted on said object, the direction being dependent on the charge. so yeah magnets can pull stuff
