We know, Kinetic Energy=1/2 * mass * velocity2
Hence, velocity2 = (2*Kinetic Energy)/mass = (2*7.5joule)/(7.9gr)
=(2*7.5joule)/(.0079kg)=1898.73(m/sec)2
Hence, velocity = square root of 1898.73 i.e 43.57 m/sec.
KE = 1/2mass * v^2
so,
98 J =1/2 (mass) *(7 m/s)^2
98 = 1/2 m49
196 = m49
4 kilograms = mass
---------------------------
kinetic energy = (1/2)m(v^2), where m is the mass in kg and v is the speed in m/s. translational kinetic energy = (1/2)m(v^2), where m is the mass in kg and v is the speed in m/s.
KE = 1/2mV2
KE = 1/2(5.0 kg)(5.0 m/s)2
= 63 Joules
========
Kinetic energy = 1/2 X m X v2
So KE = 1/2 x 5/10 x 25 = 6.25 J
the kinetic energy is 1/2 mass x velocity squared, or 122.5 joules
122.5 joules
.75 kg.
kinetic energy is motion energy, therefore any object that is moving possesses kinetic energy.
An object has kinetic energy when it is moving and not when it is at rest. When it is at rest it has potential energy.
Mechanical energy is the energy associated with the motion and position of an object. Thermal energy is the energy due to temperature.
The kinetic energy is the energy an object has because it has motion or movement. For example, a person running is an example of kinetic energy because they are moving/ have motion.
Kinetic energy is the energy that an object has because of its motion. The energy depends on the speed and mass of the object.
kinetic energy is motion energy, therefore any object that is moving possesses kinetic energy.
An object has kinetic energy when it is moving and not when it is at rest. When it is at rest it has potential energy.
Kinetic energy is the energy of motion (of an object as a whole).
Energy related to motion is called "kinetic energy".
Energy due to motion is kinetic energy.
The energy of motion is called kinetic energy.
Mechanical energy is the energy associated with the motion and position of an object. Thermal energy is the energy due to temperature.
I think you mean kinetic energy. That is energy of a moving object.
The kinetic energy is the energy an object has because it has motion or movement. For example, a person running is an example of kinetic energy because they are moving/ have motion.
Kinetic energy is the energy produced or exerted by an object in motion. The three assumptions are, that there is matter (the object exists), it is moving (in motion), and it is producing or exerting energy.
kinetic energy is the energy an object has by virtue of its motion- therefore any object that is moving possesses kinetic energy ( and the kinetic energy is proportional to both the mass of the object and the object's velocity, according to the equation KINETIC ENERGY= 1/2 mv2)
Kinetic energy is the energy that an object has because of its motion. The energy depends on the speed and mass of the object.
