... What happens if you are standing on a skateboard or a slippery floor and push against a wall? You slide in the opposite direction (away from the wall), because you pushed on the wall but the wall pushed back on you with equal and opposite force. Why does it hurt so much when you stub your toe? When ...

... The rate at which velocity changes with time is called acceleration. When a car rounds a comer at a constant speed, its acceleration is zero. As a ball falls freely, the distance it falls each second is the same. If you slide a hockey puck across a frictionless ice rink, there must be a horizontal f ...
