Solution
If you push an object in the opposite direction of its motion, the kinetic energy of the object will decrease.
Here's why:
-
Kinetic energy is the energy of an object due to its motion. It is given by the formula KE = 1/2 mv^2, where m is the mass of the object and v is its velocity.
-
If you push an object in the opposite direction of its motion, you are applying a force against its direction of motion. This is known as a retarding force.
-
This retarding force will cause the object to slow down, reducing its velocity.
-
Since the velocity (v) is squared in the formula for kinetic energy, even a small decrease in velocity will result in a significant decrease in kinetic energy.
-
Therefore, pushing an object in the opposite direction of its motion will decrease its kinetic energy.
