Right after you let go of the string and send it flying.
At the moment of release, all the energy stored in the bow (100J) is converted to the kinetic energy of the arrow. So, the kinetic energy of the arrow at that moment is 100J.
When you stretch a bow , the work done by you in stretching the bow is stored in the form of potential energy . This potential energy get converted in to kinetic energy of the bow when released.
40 Joules. This would also mean that the ideal included zero mass or elasticity in the "string" of the bow, friction is non-existent, and it is accomplished in a vacuum.
The potential energy of the mass of the sky diver is transformed into kinetic energy during the free fall. The kinetic energy of the free fall is transformed into kinetic energy and heat of the air when the parachute is deployed.
The gain in kinetic energy can be calculated using the equation: ΔKE = KE_final - KE_initial, where KE is the kinetic energy. Simply subtract the initial kinetic energy from the final kinetic energy to determine the gain.
Yes, a flying arrow has kinetic energy. Kinetic energy is the energy an object possesses due to its motion, and since the arrow is in motion, it has kinetic energy. The amount of kinetic energy depends on the mass and velocity of the arrow.
The kinetic energy of the arrow will also be 50 J, assuming that all the potential energy was converted into kinetic energy when the arrow was shot.
It has, or possesses, Kinetic Energy: the Energy of Motion.
At the moment of release, all the energy stored in the bow (100J) is converted to the kinetic energy of the arrow. So, the kinetic energy of the arrow at that moment is 100J.
no
When an archer releases an arrow, the potential energy stored in the bow is converted into kinetic energy as the arrow accelerates forward. This transfer of energy allows the arrow to travel towards its target with speed and force.
They will both have the same kinetic energy if fired from the same bow. the heavy arrow will shoot slower but hit harder while the light arrow would shoot fast but wont impact as hard. the difference wouldnt be noticible.
The kinetic energy of the arrow is dependent on its weight and the speed at which it is launched. if you use one bow to fire two different sized arrows, they will both have the SAME kinetic energy. a heavy arrow will shoot slower but hit harder while the light arrow will fly faster but wont impact as hard.
When you stretch a bow , the work done by you in stretching the bow is stored in the form of potential energy . This potential energy get converted in to kinetic energy of the bow when released.
I think you mean bow and arrow. In this case, when you pull back an arrow on a bow, you apply kinetic energy (the energy of motion) to the bow and arrow to give it potential energy (energy that can be turned into kinetic energy at a later time). Anyway, the laws of conservation of energy state that energy cannot be created or destroyed; therefore all energy in the world is only changed to other different forms. As I said above, your kinetic energy (coming from your body) applied action to the bow and arrow, making the kinetic energy change into potential energy. Of course, when you let go of the arrow, the potential energy changes back into kinetic energy, allowing to arrow to fly off.
The energy conversion that takes place as an arrow is shot from a bow is from potential energy stored in the bent bow to kinetic energy of the arrow in motion. When the bowstring is released, the potential energy is rapidly transformed into kinetic energy as the arrow accelerates forward.
Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.
