How would you work out the kinetic energy of an object when you are only given its weight and how far it has moved?

The value for kinetic energy is given by the formula (mass * velocity^2)/2. Since we have weight (not the same as mass) and distance moved rather than velocity we can't calculate the kinetic energy.
You should note that weight and mass are not equivalent. Weight is measured in Newtons, while mass is measured in kilograms.

What term describes the amount of energy a moving object has?
An object's kinetic energy is energy entirely due to its motion. The kinetic energy of an object, at some given speed, is the work needed to accelerate that body from rest to the given speed.

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 is an object's kinetic energy if air resistance is not a factor and weighs 0.6 kg and its potential energy is 27 joules?
The object's kinetic energy can't be determined from the given information. Kinetic energy = (1/2) (mass) (speed)2 The question gives the object's mass, but we need its speed too.
What equation use for kinetic energy?
Kinetic energy for a moving object is given as KE=mv 2 where KE is the kinetic energy, m is the mass and v the velocity.
What is the difference between momentum and kinetic energy and why is it that kinetic energy can be changed in to other forms of energy but momentum cant?
Firstly, momentum is not a form of energy; the question seems to imply so. Kinetic energy is the energy possessed by a moving object. That energy is provided by a source, and can be removed from the object because energy possessed by an object is not an inherent part of that given object. Momentum is a property of mass; momentum is inherent in the mass of the object, and cannot be removed or put somewhere else, only altered.
How do you find force while given kinetic energy and distance?
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
What two factors determine an object kinetic energy?
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
When is kinetic energy transfered from object to object?
kinetic Energy. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. For the blue ball to move to the position of the green ball, energy must be given to the blue ball.
What kind of energy does a skate board have?
In physics, the kinetic energy of an object is the energy that the object possess, due to the fact that the object is moving. When the object/skateboard isn't moving it has no kinetic energy. However when it is given energy such as a push, it would move and keep going until it is stopped by another force, such as a wall.
What two points do Kinetic energy increase the most?
Kinetic energy depends on mass and speed. For a given object (whose mass will normally not change much), it will be greatest when the speed is greatest.
Why is potential energy greater than kinetic energy?
It isn't so. Potential energy can be greater, or less, for a given object, depending on its position and its speed.
