This truck has a lot of mass. Mass is a measure of the number of atoms in an object combined with the density of those atoms. Usually people measure mass in kilograms. You can tell how much mass something has by measuring how hard it is to get that thing to change directions or slow down. If you're driving a [...]

Tegla Loroupe, Kenyan runner Acceleration is how much your speed changes in a certain amount of time. Picture yourself standing in front of your house. When you stand still, your acceleration is zero. When you begin to walk, your speed is changing - that's what acceleration is - it measures how fast your speed [...]

How hard will the ball hit the catcher's glove? It depends how big the ball is. how fast the pitcher throws it, and how far away the catcher is. Like the First Law of Motion, the Second Law of Motion started out with work in the medieval Islamic Empire, about 1000 AD in [...]

Gravity is an important cause of acceleration Newton's Second Law of Motion tells us that force equals mass times acceleration. You can try this out for yourself. Here's a website with a good experiment you can do. More about the Second Law of Motion More about Ibn Sina Bibliography and further reading about Newton's [...]

Pedaling will make her accelerate. So will going downhill. Acceleration is a way to measure how fast something is speeding up. Suppose you are riding your bike. You start out going very slowly, hardly pedaling at all. Now you begin to pedal as hard as you can, to speed up - you are [...]
