The work (energy) done on an object is Force x Distance. If there is no friction, and the object started at rest, then this will also be the kinetic energy that the object has.
Then the kinetic energy, Ek = F * d, so F = Ek / d

A net force of 22 N accelerates a 4-kg mass over a distance of 18 m. What is the work done by this net force What is the increase in kinetic energy of the mass?
Work done by a force (W) = Force (F) x distance (m) W = 22 x 18 = 396 Joules According to the law of conservation of Energy, the total energy of a closed system is constant, but can change from one type to another. Therefore, the work given to the object must be converted into the kinetic energy of the object. So, Increase in Kinetic energy = work done = 396 Joules
How do you find mean kinetic energy when given only mass and horizontal distance traveled?
You don't have enough information in this case. Kinetic energy depends on mass and speed. Speed can be calculated as distance / time - and no time is given, nor is there any other information that allows you to calculate the time. Note that even if time is given, you can calculate the average (mean) speed, but that will only give you a rough idea of the mean kinetic energy. In this problem, if the speed changes a lot, the average kinetic energy (averaged over time) will be greater than in the case of a constant speed. This is because kinetic energy is proportional to the square of the speed.
How do you find kinetic energy if no final velocity is given?
Kinetic energy is equal to potential energy during the change
What is the capacity of a body or system to do work called?
In Physics, the capacity or ability to do work is called ENERGY. The two main forms of Mechanical energy are KINETIC (related to motion) and POTENTIAL (related to a field of force). Kinetic energy is given by: 1/2 x mass x velocity squared Potential energy is given by mass x gravitational force x height If SI units are used, the answer is in Joules. 1 Joule of energy = 1 Newton.metre of work
What is average kinetic energy of the particles of matter in a given space?
Temperature
A cart pushing ten bricks or a cart pushing twenty bricks using the same force and going the same distance which has greater kinetic energy?
The same force could not be applied to travel the same distance if there is a larger mass in one instance. Applied force will accelerate a given mass twice as much as a mass half as large. If both are moving the same distance, the 20-brick cart had more kinetic energy when in motion.

What is the relationship between kinetic energy and work?
Relationship between work and kinetic energy. Work is defined as the result of a force moving an object a distance and is stated by the equation W=Fd. But the result of the force being applied on the object also means that the object is moving with some given velocity, according to the equation for force as F=ma. From those two equations, it can be shown that work is equivalent to kinetic energy Kinetic Energy =1/2mv2
Is kinetic energy a force motion or energy?
Kinetic energy is energy. It can be transformed to other types of energy. And as energy it can be applied to do work. If an elastic ball is dropped from a given height, it will develop kinetic energy at the expense of its potential energy. An instant before collision with the floor, its kinetic energy amounts to the original potential energy of the ball with respect to the floor. (if we can neglect air resistance).
What is the name given to energy?
kinetic energy
What is zonal kinetic energy?
Zonal kinetic energy is the amount of kinetic energy distributed by a zonal wind at a given latitude.
When kinetic energy is the heighest?
Kinetic Energy is given by,KE = 1/2mv2 So, Kinetic energy is highest when velocity is highest..

How do you calculate force when only given distance and power?
You can't because you need the time involved. Force x distance shifted in the direction of the force = energy. But power is energy per unit time (seconds etc)
How do you find kinetic energy if no final velocity is given?
Kinetic energy is equal to potential energy during the change
Which of the quantitative properties would double if you doubled the mass of an object?
-- weight -- momentum when moving -- kinetic energy when moving -- force on it needed to produce a given acceleration -- potential energy at a given height
What are two factors of work?
The technical definition of 'work' in Physics is (force) times (distance).So I suspect the factors you're fishing for are force and distance.
