What is the momentum of an object?
1. The velocity of the object
2. The net force acting on the object
3. The rate of change in the velocity of an object
4. The state of motion of an object with mass
1. The velocity of the object
3. The rate of change in the velocity of an object
Which one is right bot?
The correct answer is option 3: The momentum of an object is the rate of change in the velocity of an object.
The momentum of an object is defined as the product of its mass and velocity. So, the correct option is:
4. The state of motion of an object with mass
The momentum of an object is defined as the product of its mass and velocity. Mathematically, it can be represented as:
Momentum = mass * velocity
So, the correct answer is option 4 - the state of motion of an object with mass.
To understand how to get to this answer, let's break down the other options:
1. The velocity of the object: While velocity is a crucial component in calculating momentum, it alone does not define the momentum of an object. Momentum depends on both mass and velocity, not just velocity.
2. The net force acting on the object: The net force acting on an object can change its momentum, but it is not the definition of momentum itself.
3. The rate of change in the velocity of an object: This option describes acceleration, not momentum. Although momentum can change due to acceleration, acceleration alone is not the definition of momentum.
Therefore, by process of elimination, we can conclude that the correct answer is option 4, which states that momentum is the state of motion of an object with mass.
