Question

If the speed of a moving object doubles what else doubles

Answer 1

Momentum, kinetic energy and acceleration doubles when the speed of a moving vehicle doubles.

Answer 2

The linear momentum doubles.

• Let's assume that an object of mass m is moving along a straight line with a velocity of v.

So, the initial linear momentum is

$P_{i} = m \times v = mv$

Now, when velocity is doubled (i.e. 2v), the linear momentum becomes:

$P_{f} = m \times (2v) = 2mv = 2P_{i}$

Similarly, the distance covered in equal time interval also doubles.

• Initially, let the distance covered in time t be D

$D = v \times t = vt$

Now, after doubling of velocity, the new distance covered in same time will be :

$d = (2 v) \times t = 2vt = 2D$
