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

To find force using kinetic energy and distance, you need more information. You also need the time taken to cover the distance or the speed at which the object is moving. With this additional information, you can apply the work-energy principle, which relates the work done on an object to its change in kinetic energy to calculate the force.

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?
To find the mean kinetic energy with only mass and horizontal distance traveled, you would also need to know the initial and final velocities of the object. Once you have these values, you can calculate the mean kinetic energy using the formula: KE = 0.5 * m * ((v_final)^2 - (v_initial)^2), where m is the mass and v is the velocity.
Work-kinetic energy theroem expression?
The work-energy theorem states that the work done on an object is equal to its change in kinetic energy. Mathematically, the expression for the work-energy theorem is given as: W = ΔKE, where W is the work done on the object and ΔKE is the change in kinetic energy of the object.
What is the coefficient of kinetic friction between the 13.0kg wooden crate and the horizontal force of 31N of the floor?
The coefficient of kinetic friction can be calculated using the formula: coefficient of kinetic friction = force of kinetic friction / normal force. The force of kinetic friction can be found using the formula: force of kinetic friction = coefficient of kinetic friction * normal force. Given the force of 31N and normal force equal to the weight of the crate (mg), you can calculate the coefficient of kinetic friction.
A body of mass 5 kg initially at rest is subjected to a force of 20N What is kinetic energy acquired by the body at the end of 10s?
The kinetic energy acquired by the body can be calculated using the work-energy principle. The work done by the force is given by W = F * d, where d is the distance moved by the body. If the body was initially at rest, then the work done is equal to the change in kinetic energy, which can be calculated as KE = 1/2 * m * v^2. Given the force and time, you can calculate the final velocity of the body using the equation F = m * a and then find the kinetic energy acquired.
What is the transfer of energy that occurs when a force makes an object move?
The transfer of energy that occurs when a force makes an object move is called kinetic energy. Kinetic energy is the energy possessed by an object due to its motion. The amount of kinetic energy an object has depends on its mass and velocity.
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
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 cart pushing twenty bricks will have greater kinetic energy because kinetic energy is directly proportional to both the mass and the square of the velocity of an object. In this case, the increased mass of twenty bricks will contribute more to the kinetic energy than the increased force.
What does a force moving an object through a distance transfer?
The work done by the force transfers energy to the object in the form of kinetic energy, increasing its speed or changing its direction.
What if A man pushes a sled across the snow using a force of 300 N over a distance of 2 m. What is the kinetic energy of the sled after he pushes it Assume there is no friction.?
The kinetic energy of the sled can be calculated using the formula KE = 0.5 * mass * velocity^2. Since no velocity is given, we can find it using the work-energy principle: Work done = Change in kinetic energy. The work done by the man is 300 N * 2 m = 600 J, which equals the change in kinetic energy of the sled. Given that initial kinetic energy is 0 J, the final kinetic energy of the sled is 600 J.
What is the relationship between kinetic energy and work?
Work is the transfer of energy, and kinetic energy is the energy of motion. The work done on an object can change its kinetic energy by either increasing it (by doing positive work) or decreasing it (by doing negative work). The relationship between kinetic energy and work is that work done on an object can change its kinetic energy.
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
How do you find mean kinetic energy when given only mass and horizontal distance traveled?
To find the mean kinetic energy with only mass and horizontal distance traveled, you would also need to know the initial and final velocities of the object.

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)
When kinetic energy is the heighest?
Kinetic Energy is given by,KE = 1/2mv2 So, Kinetic energy is highest when velocity is highest..
What is kinetic energy versus square velocity?
Kinetic energy is the energy possessed by an object due to its motion, given by the formula KE = 0.5 * mass * velocity^2. Square velocity refers to the squared value of the velocity of an object. Since kinetic energy is directly proportional to the square of velocity, a small increase in velocity can result in a larger increase in kinetic energy.
