Your ideal scenario describes the near-perfect vacuum and weightlessness of space. As you said, a one-kilogram mass will accelerate at one meter per second squared if a net force of one newton is applied to it. But you wish to know what happens under real-world conditions, such as the existence of friction (air resistance, rolling friction, and sliding friction) and gravity. If the motion is in the horizontal plane and at low speeds, air resistance is negligible. Friction between surfaces and rolling friction are significant, however, and will act against any force used to accelerate an object. Gravity plays a role in the consideration of friction, as well, inasmuch as the frictional force is proportional to the Normal Force, which is related to the object's weight.1 For motion in two directions, such as the path of a kicked ball or the trajectory of a bullet fired from a gun, air resistance plays a large role as does the acceleration of gravity. Friction and the effects of gravity play a major role in calculations involving the motion in the vertical direction, whereas the acceleration of gravity plays no role in the calculations of the motion in the horizontal direction.2Basically, keep in mind that weight is a force directed downward. When determining the net force acting on an object, its weight is just one of the forces acting on it. 1. For an object resting on a flat surface with zero incline, the Normal Force is equal and opposite to the object's weight (W = mg). The frictional force is calculated to be uN, where u (the Greek letter mu) is the coefficient of friction. The frictional force opposes the direction of motion. For objects on an inclined plane, the Normal force is equal to W*cos(theta), where theta is the angle of incline. 2. Weight is a force perpendicular (orthogonal) to horizontal motion and, hence, can have no effect upon it.
Not enough information. But basically, you need to use Newton's Second Law: you need to divide the force by the mass of the yo-yo.
A measured value is one that is directly obtained from the environment, such as using a scale to weight something. To calculate a value is to figure it out using other values. For example, if you know the distance something traveled and the time it took, you can calculate its speed.
You can calculate the sum of numbers by adding numbers together. You can calculate the product of numbers by multiplying those numbers.

Since , V = u + at, we get , a = v - u /t = 402.3 - 0 /9.013 = 44.6355264617 ms-2 Therefore, acceleration = 44.6355264617 ms-2

The answer would be 80kg/ms or 80N because: force= mass x acceleration = 20kg x 4ms =80kg/ms =80N
Because unit costs are computed by departments or processes at fixed time intervals.
Some electrical devices that protect our environment include solar panels and computers. Solar panels collect power from the sun while computers help calculate efficient ways to operate equipment.

force is mass x acceleration which for orbit is mass (m) x velocity squared (v^2)divided by radius (R) above center of earth. Since there is also acceleration of gravity (g) then g = v^2/R. You can now calculate velocity of satellite to stay in orbit - it is about 17.500 mph
