An object that has kinetic energy must have momentum, velocity, and speed. Momentum is mass times velocity. Kinetic energy is mass times velocity squared. Speed is distance divided by time. Kinetic energy is the energy of the object's motion. An object that has kinetic energy must have momentum because is the force or speed of movement. For example the ball gained momentum as it rolled down the hill. An object that has kinetic energy must have momentum, velocity, and speed because if an object is in motion (has kinetic energy) it must be either gaining, losing, or at a constant momentum, it must have a velocity (basically speed) and speed because when an object is in motion, it MUST have a certain velocity or speed.

∙ 15y agoNot necessarily. Look at this explanation. Kinetic energy is energy posessed by moving objects. Therefore it would not be wrong to say that an object which has velocity has kinetic energy. However, I recently learned in my physics class that a stationary object (at any temperature above absolute zero, of course) can possess kinetic energy in the form of internal energy. The atoms and molecules within the substance will be constantly vibrating/ constantly in motion, so they will possess kinetic energy. You can check the following website for a really cool animation (or at least I think it's cool)... http://www.s-cool.co.uk Check under A-level physics in the section that says "Power and internal energy"......hope that cleared up your confusion! ;-)

If an object has kinetic energy then it must also have potential energy?
FALSE
Which factors must be known to calculate an object's gravitational potential energy?
To calculate an object's gravitational potential energy, the following factors must be known: Mass of the object: The gravitational potential energy of an object depends on its mass. The greater the mass of the object, the greater the gravitational potential energy. Height or distance: The gravitational potential energy of an object also depends on its height or distance from the reference point. The greater the height or distance of the object from the reference point, the greater the gravitational potential energy. Acceleration due to gravity: The gravitational potential energy of an object also depends on the acceleration due to gravity at the location of the object. The acceleration due to gravity is a constant value on the surface of the Earth, approximately equal to 9.8 meters per second squared. The formula for gravitational potential energy is: PE = mgh Where PE is the gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height or distance of the object from the reference point.
If an object's mechanical energy is equal to its potential energy how much kinetic energy does it have?
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.
An object that has linear kinetic energy must be?
Moving. Linear kinetic energy is basically the same thing as regular kinetic energy. hope that helps!
Why is it hard to stop fast moving cars?
A fast moving object has a lot of kinetic energy that must be taken away to stop the car.
If an object has kinetic energy then it must also have potential energy?
FALSE
How does kinetic energy and potential energy switch?
work=change in kinetic energy, doing work on an object by moving it up increases that object's potential energy because it has the POTENTIAL to fall due to gravity. kinetic energy is lost in the movement of the object. However, throughout an entire closed system, the total energy in joules (or kinetic enery plus potential energy) does remain constant. this is useful because the initial energy and the final energy most be equal, and if thats true, then initial kinetic energy plus initial potential energy must equal final kinetic energy plus final potential energy. does that help?

Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.
When calculating gravitational potential energy you must use?
the distance between the object and the center of the Earth
Can an object have no either potential energy and kinetic energy?
Yes. Potential energy is energy that has not yet been released. Kinetic energy is energy or an object already in motion.Think of a ball 1 mile up in the air that begins to fall. After it has fallen 10 feet, releasing some, but not all of its potential energy, it has built up some kenetic energy as well from the motion of falling 10 feet, but still has 5270 feet worth of potential energy to go. What happens as the ball falls is that it gradually changes all of its potential energy into kinetic energy.co

How do objects acquire potential energy?
For an object to require potential energy a force must be acting on it in a certain direction. Even though the object doesnt move doesnt mean it has potential energy. The most common force of otential energy is Gravity. When an object is lifted off the ground gravity becomes stronger. For a formula of proof then use E=FxD (Energy=Force applied x Distance travelled). If a ball has been lifted by 10 Meters with a force of 500 Newtons then it has a Potential Energy of 5000 Newton Meters,
What two properties does the amount of potental energy depend upon?
Weight and height. The potential energy of an object is its weight times its height. The potential energy is turned into kinetic energy as the object is dropped. Potential energy is weight times height, kinetic energy is one half mass times velocity-squared. Mgh = ½ M V^2 To reach a speed of 10 m/s this equation can be solved to show that the object must be dropped through a height of 5.1 metres.
