Well it is a question of Projetile Motion. Whenever you project an object at some angle with horizontal it traces a curved path. Suppose 'x' be the angle with horizontal, 'm' be its mass, 'u' be its initial velocity. You might be knowing that any vector can be resolved into horizonal and vertical component. Here horizontal component of velocity will be ucosx and vertical will be usinx. At highest point the vertical component of the velocity will become zero. Hence it will have no velocity in vertically upward direction. It will only have velocity in horizontal direction which will be 'ucosx'.(The horizontal component of initial velocity will not affected by force of gravity and hence it will be constant throughout the motion.) So kinetic energy at highest point is: KE=0.5*m*(ucosx)^2 KE=0.5*50*(200*cos60)^2=25*10000=250000 J
KE = 1/2 m V2 = 1/2 (50) (80)2 = 25 x 6400 = 160,000 joules.
The direction of the shot doesn't matter.
Kinetic Energy = 1/2 M V2 = (25) (80)2 = 160,000joules.
To measure kinetic energy:Let us suppose an object of mass m moving wtih velocity vKinetic Energy of that object= mv2/2
The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.
The unit of Kinetic Energy is Joule. So, 125 KE can be written as 125 Joules.
The bike's kinetic energy is 45 joules.
As the object falls, it PEG or potential gravitational energy becomes kinetic energy. Before falling, it has for example 10 joules of PEG and 0 joules of Kinetic energy. As it falls, the PEG decreases and the kinetic energy increases, until it hits the ground, when all the energy is dispersed as sound, heat, etc.
Joules, all energy is measured in joules.

No, kinetic energy is measured in Joules (J), as this is the SI unit for energy.
The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.
Energy related to motion is called "kinetic energy".
The joule is the unit associated with kinetic energy
The SI unit of kinetic energy is joules(j)
joules
The object's kinetic energy is 2,500 joules.
They are both measured in Joules
