Momentum is basically a way of measuring how hard it is to stop something that's moving.
In physics terms, momentum is the product of an object's mass and its velocity. The formula looks like this:
Momentum=mass×velocityorp=m⋅v\text{Momentum} = \text{mass} \times \text{velocity} \quad \text{or} \quad p = m \cdot vMomentum=mass×velocityorp=m⋅v
Mass (m): how much stuff is in the object.
Velocity (v): how fast and in what direction it's moving.
Momentum (p): how much motion it has.
So a truck going fast has a lot more momentum than a bike going at the same speed, because the truck has more mass.
Momentum is also vector-based, which means direction matters. If two things crash into each other, their momentums can cancel out or add up depending on which way they’re going
If something is heavy and fast, it has a lot of momentum.
If it’s light and slow, it has a little momentum.
So…
A bowling ball rolling fast? 💥 Hard to stop — lots of momentum.
A feather drifting slowly? 🪶 Easy to stop — barely any momentum.
It’s like “motion power.” The more momentum, the more it keeps going unless something stops
