Question

As a car increases velocity, does its kinetic energy or momentum increase faster? Explain.

Answer 1

Step-by-step explanation:

The kinetic energy of an object is associated with its motion. Mathematically, it is given by :

`E_k=(1)/(2)mv^2`........(1)

Where

m is the mass of the car

v is the velocity of the car

And the momentum of an object is equal to the product of mass and velocity i.e.

`momentum(p)=mass(m)* velocity(v)`..........(2)

From equation (1) and (2) it is clear that the kinetic energy and the momentum is directly proportional to the velocity of the object. As a car increases velocity, its kinetic energy or momentum increase faster.
