Solution

Kinetic Energy

  1. The kinetic energy of an object is the measure of the work it does as a result of its motion.
  2. Kinetic energy is used in everyday activities such as walking, jumping, throwing, and falling.
  3. The work that an object can produce as a result of its motion is measured by its kinetic energy.
  4. Kinetic energy is a scalar quantity that can only be defined in terms of magnitude.
  5. The kinetic energy of a positive charge increases as it goes down the potential gradient.
  6. When a positive charge is moved in an electrostatic field from a point at a high potential to a low potential, its kinetic energy increases.

The equation for kinetic energy is as follows:

K.E.=12mv2

Where,

K.E is the kinetic energy.

m is the body’s mass.

v is the body’s velocity.
