graphic defining acceleration as a change in velocity over time

What is acceleration?

ACCELERATION IS THE CHANGE IN VELOCITY OVER TIME, JUST LIKE SPEED IS THE CHANGE IN DISTANCE OVER TIME.  Have you ever been on a roller coaster? They start off slow. You can move around and lean forward in your seat with almost no energy, but when they start to speed up, like at the first … Continue reading What is acceleration?

What is Momentum?

Changing speed is different for different things depending on their current speed and size, or their mass.  To understand this, we use something called momentum. MOMENTUM IS WHAT WE GET WHEN WE MULTIPLY THE MASS OF AN OBJECT BY ITS VELOCITY. A large semi-truck traveling at 60 mph will have more momentum than a small car at the … Continue reading What is Momentum?
