The kinetic energy of an object of mass, m moving with a velocity of is , What will be its kinetic energy when its velocity is doubled? What will be its kinetic energy when its velocity is increased three times?
Step 1: Given data
The kinetic energy of an object (K.E) =
The velocity of the object (V) =
Mass of the object = m
Step 2: Formula used
For the mass of the object
Step 3: Calculation
Case 1:
When velocity is doubled, then
So
So its kinetic energy is when its velocity is doubled.
Case 2:
When its velocity is increased three times, then
So
So its kinetic energy is when its velocity is increased three times.
