Physics

If you double mass and double velocity, you get eight times the kinetic energy, no matter what your first energy is. As an object’s kinetic energy increases, and momentum is mass x velocity.

The unit of the physical quantity “Jerk” is meter per second cube.

They are single to naked eye because they are far from us. But, if we see with telescope We can observe that there are two or double stars.

When an object falls through a fluid, it attains a constant velocity through its subsequent motion. This happens because the net force on the body due to gravity and fluid becomes zero. This constant velocity is termed as terminal velocity.
