Momentum: The Measure of Motion

Movement is a big deal in physics. It's all about how much motion an thing's got. It's just the weight of the thing times its velocity.

It's like how hard it would be to attempt to stop it if it's already moving. Say, a large heavy vehicle moving slow, it's got the same amount of movement as a small sports vehicle going really fast. And it's because it's all about both how much material the thing is (weight) and how fast it's going (velocity).

Impulse: The Change in Momentum

Impulse is all about how much movement changes within a period of time. It's mostly just how we calculate how forces affect objects.

The formula of impulse? Extremely simple: it's just the change in movement. This this indicates that if you exert a force onto an object for a specific duration, you can determine the impulse and, hence, the change in movement.

Collisions: The Interactions of Objects

Impacts are when two things hit each other and change their movement. And there are two kinds of Impacts: elastic and inelastic.

In an perfectly elastic collision, you preserve all of your momentum conservation and kinetic energy lost. So, if you release a ball on a rigid surface, it'll rebound at the same speed it came down at. But in an inperfectly elastic collision, you only keep your momentum conservation. Some energy might turn into heat or sound and be lost.

Test Review: Preparing for Success

So, you're getting the hang of momentum conservation, impulse, and Impacts now, right? It's time to take them for a test run! Prepping for a physics exam can be kind of intimidating, but just hit the correct approach, and you'll do great!

First thing's first, just revisit those important concepts and formulas in your head. After that, attempt to solve some practice problems. And last but not least, do a couple of rehearsals to become familiar with the format and timing.
