Momentum is a measure of an object's motion, calculated by multiplying its mass by its velocity.
Momentum is directly proportional to both the mass and velocity of an object. This means that as either the mass or velocity increases, so does the momentum.
To calculate the momentum of a 15 ton train, you will need to know its mass (15 tons) and its velocity. Once you have this information, you can use the formula p = mv, where p is momentum, m is mass, and v is velocity, to calculate the momentum of the train.
Yes, momentum can change. This can occur if the mass or velocity of an object changes. For example, if a 15 ton train is traveling at a constant speed, its momentum will remain the same. However, if the train starts to slow down or speed up, its momentum will change.
Momentum is important because it helps us understand how objects move and interact with each other. It also helps us predict the behavior of objects in motion and is a key concept in many fields of science, including physics and engineering.
