Correct Answer - Option 4 : All of the above can change the momentum of the object
CONCEPT:
-
Momentum: A property of a body in motion that is equal to the product of the body's mass and velocity is called momentum.
\(\overrightarrow{P}=m\overrightarrow{v}\)
where P is the momentum of the body, m is the mass of the body, and v is the velocity of the body.
EXPLANATION:
-
Option 1: Momentum is calculated by \(\overrightarrow{P}=m\overrightarrow{v}\).
- If we change the mass of the object m, the linear momentum P will also be changed.
-
Option 2 and 3: If we change the velocity of the object \(\overrightarrow{v}\), the linear momentum will be changed.
-
Velocity is a vector quantity. It means by changing the direction or by changing the magnitude (speed), we can change the velocity.
- So, the Linear momentum of an object can be changed by changing the mass, velocity (speed, and direction) of the object.
- Hence the correct answer is option 4.
