If the mass of an object is halved and its velocity remains the same, its momentum will be halved.
Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.
We can calculate the momentum of an object using the following expression.
p = m × v
where,
The initial momentum of the object is:
p₁ = m₁ × v₁
If its mass is reduced by half but its velocity remains the same, the new momentum is:
p₂ = m₂ × v₁ = 0.5 m₁ × v₁ = 0.5 p₁
If the mass of an object is halved and its velocity remains the same, its momentum will be halved.
