Question

What happens to the kinetic energy of a particle if
(a) The speed v of the particle is made 2v.
b) The mass m of the particle is made m/2 ?​

Answer 1

$\huge\bigstar\underline\pink{Answer}$

Kinetic Energy = 1/2 × mv²

a) if speed changes from v to 2v

k.E = 1/2 × (m4v²)

b) If mass of the particle changes from m to 2m

new, K.E will be 1/2 × 2mV²
