What is an example of an object with great momentum? Why does it have great momentum?

Since momentum equals M*V, for a large momentum you need either a very large mass (M) or a very large velocity (V), or both.

How about a fired bullet or a moving freight train?

Oh, I see. Thank you!

An example of an object with great momentum is a moving car. The car has great momentum because it has a large mass and is traveling at a high velocity.

Momentum is defined as the product of an object's mass and velocity. The greater the mass of an object and the faster it is moving, the greater its momentum. In the case of a car, it typically has a significant mass due to its size and the materials used in its construction. Additionally, cars are designed to travel at high speeds, so they often have a considerable velocity.

To calculate the momentum of an object, you can use the equation:

Momentum = mass × velocity

By knowing the mass of the object and its velocity, you can determine its momentum. In the case of a car, due to its large mass and high-speed movement, it possesses significant momentum.
