What will be the ratio of position energy and kinetic energy relative to the ground at maximum height of projected motion?
If the velocity at the top most point of the projectile motion is v and the radial distance from the center of the earth to this point is r then the centrepetal force acting on the body of mass m is equal to the gravitational force acting on the body. Ratio of potential energy to kinetic energy = 2h(R+h)/R^2.
What is the ratio of potential energy and kinetic energy?
According to the virial theorem, the kinetic energy is half of the negative of potential energy. The potential energy is the double of the negative of kinetic energy. The total energy is equal to the negative of the kinetic energy. The total energy is equal to half of the potential energy.
Is there kinetic energy at the top of a projectile?
Therefore, at the highest or at maximum height, the net velocity is u= vocosθ. So, we can say that at the maximum height, the kinetic energy is minimum as the vertical velocity is zero.
What is the ratio of potential energy?
P.E:T.E = 2:1.
What is highest point Pe?
Gravitational and elastic potential energy
| Gravitational P.E. | Kinetic E. | |
|---|---|---|
| (3) Highest Point | 2mgypull | 0 |
| (2) Equilibrium | mgypull | 12mv2 |
| (1) Lowest Point | 0 | 0 |
What is the relation between kinetic energy and height?
As the height increases, there is an increase in the gravitational potential energy P and a decrease in the kinetic energy K. The kinetic energy K is inversely proportional to the height of the object.
What is ratio of KE and PE of electron?
The ratio of kinetic energy and potential energy of an electron in a Bohr orbit of a hydrogen-like series is -1/2. Hence, the correct option is B.
What is the ratio of kinetic energy and potential energy of an electron in an orbit?
Ratio = kinetic energy / potential energy = [13.6/ n²] / [-2× 13.6/n²] = 1/(-2) = 1 : -2.
What is the ratio of kinetic energy potential energy and total energy of an electron in Bohr’s atomic model?
The ratio of kinetic energy to the total energy of an electron in a Bohr orbit of the hydrogen atom, is. 1:1.
