Which has the most kinetic energy a 1000 kg car traveling 30 ms or a car traveling 45 ms?
RoxanneFox
WOW, 5 MILES PER SECOND. I guess that I would have to calculate the miles per hour. To do this, we must multiply 5 miles per second times 3600(the number of seconds in an hour). That is 18000 miles per hour. I like to work in the SI system, so by converting this to meters per second, we get 8.04672E3 meters per second. Kinetic energy is defined as one half mvsquared. The Kinetic Energy is equal to 3.2374E10 Joules.

∙ 9y agoI suggest you calculate the kinetic energy for each case, then compare. The formula for kinetic energy is (1/2) m v squared.

For having the same mass for both velocities, the car moving with velocity 45 meter per second will be having higher kinetic energy as the kinetic energy is directly proportional to the square of the velocity for equal mass.

What If you have four balls all traveling at 5 meters per second which one has the most kinetic energy?
If several objects have the same speed and the same velocity,then each has the same kinetic energy.
When an object loses kinetic energy due to a force of kinetic friction is the loss of kinetic energy transformed primarily into potential or thermal energy?
Kinetic friction is associated with thermal energy (and sound or light).
Formula for mechanical energy?
potential energy+kinetic energy=mechanical energy
As a rocket rises its kinetic energy changes. At the time the rocket reaches its highest point most of the kinetic energy of the rocket has been and mdash?
When an object - rocket or otherwise - rises, its kinetic energy gets converted to gravitational potential energy. At its highest point, if it rises directly upwards, all the kinetic energy will be converted to gravitational potential energy. However, its movement may also have a sideways component; in that case, not all the kinetic energy is converted to potential energy.
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?

As rocket rises its kinetic energy changes at the time the rocket reaches its highest point most of the kinetic energy in the rocket has been?
Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.
Thermal energy is comprised of?
kinetic energy
Which state of energy has the most kinetic energy?
Gaseous State
Can you give some types of kinetic energy?
There are many different forms of kinetic energy, but there are three that are most common. Linear Kinetic Energy (straight line motion) Rotational Kinetic Energy (Like a spinning top) Spring Kinetic Energy (A spring oscillating back and forth)
Describe a stone falling off the tabletop in terms of both kinetic energy and potential energy?
Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.
What kind of energy is it when a big fan blows down a row of dominoes?
Its called kinetic energy. Most energy that involves movement is kinetic energy.
When do molecules have the most kinetic energy?
When they are moving.
Does kinetic energy have chemical energy?
no, kinetic energy is the energy below so if u hold a ball up in the air it has most potential energy but if u drop the ball the potential energy goes down and the kinetic energy goes up.
How kinetic energy and potential energy vary?
Well, the most potential energy is when your going slow or your stopped. The most kinetic energy is like at the bottom of a hill over the first hump in a rollarcoaster, when your going your fastest. Your speed and probably friction will affect it.
How does kinetic energy change with each state of matter?
When any substance goes from solid to liquid to gas, the kinetic energy of the molecules increases.Molecules in the gaseous state have the most kinetic energy.Molecules in the solid state have the least kinetic energy.
Which phase of matter do particles have the most energy and the least energy?
Particles of matter have their least kinetic energy in the solid phase and their greatest kinetic energy in the gas phase.
