Although the mass of the bullet is less its high speed renders double the amount of kinetic energy. As you can see from the formula if the object has no speed then its kinetic energy is zero.
Falling would also seem to be a.
An object that has kinetic energy must be. An object that has kinetic energy must be moving A cannonball has more kinetic energy than the recoiling cannon from which it is fired because the force on the ball. An object that has kinetic energy must be a moving. D at an elevated position.
E none of these. An object that has kinetic energy must be. In physics we know that the kinetic energy of an object is the energy that it possesses due to its motion.
It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Hence An object that has kinetic energy must. Kinetic energy is the energy of motion so the object must be moving.
Falling would also seem to be a. An object that has kinetic energy must be moving. The formula for an objects kinetic energy is.
KE 12 the objects mass the objects speed². As you can see from the formula if the object has no speed then its kinetic energy is zero. A bullet fired from a gun has very high kinetic energy and so it can easily penetrate any object.
This is because of a large amount of velocity possessed by the bullet. Although the mass of the bullet is less its high speed renders double the amount of kinetic energy. Kinetic energy is the energy that is associated with motion.
So what you have to have is an object that is in motion but still has more energy that it has yet to convert into kinetic energy. Examples of Kinetic Energy. The kinetic energy of falling water is used to run the turbines.
A fast-moving car possesses a lot of KE due to its mass and velocity. Flowing water possesses kinetic energy due to its motion. A strong windstorm blows off the leaves from its tree due to KE.
Find an answer to your question An object that has kinetic energy must have _____. C a force applied to maintain it. An object that has kinetic energy must be A moving B falling C at an elevated Course Hero An object that has kinetic energy must be a moving b School Santa Monica College Course Title PHYSIC 14.
An object that has kinetic energy must a. At an elevated position. If an object has kinetic energy then it must also have a.
Acceleration 1 See answer DaneGil1996 DaneGil1996 The answer is impulse Because Where m is mass v is velocity a is acceleration New questions in Physics. The kinetic energy is an important component of energy that a particle or a system of particles has due to its motion. The magnitude of this energy is directly proportional to the mass and the.
An orange rolling down an incline has its maximum kinetic energy at the bottom When a drawn bow of potential energy 60 J fires an arrow the arrow will ideally have a kinetic energy. Kinetic energy form of energy that an object or a particle has by reason of its motion. If work which transfers energy is done on an object by applying a net force the object speeds up and thereby gains kinetic energy.
Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. Any object that is freely falling due to gravity has kinetic energy. The kinetic energy of air is used to run the windmills.
The earth revolving around the sun has kinetic energy. An Electron revolving around the nucleus has kinetic energy etc. A piece of zinc was lying outside and had a temperature of 26 o C.
Later that day the sun came out and the temperature increased to 36 o C. If the piece of zinc is only 015 kg find the thermal energy. Specific heat of zinc is 380 Jkg o C.
