The mass is just sitting there motionless. There is no acceleration and it is in equilibrium. What does this mean? This means that the net force in the y-direction (vertical direction) must be zero. I ...

Forces may change the shape of an object. An elastic object, such as a spring, stores elastic potential energy when stretched or squashed. The extension of an elastic object is directly proportional ...

There are different ways to investigate the relationship between force and extension for a spring. In this practical activity it is important to: measure and record length accurately measure and ...

We investigate Hooke's Law and explore the concept of spring potential energy. Segment 4G: Spring Potential Energy We investigate Hooke's Law as we explore the concept of spring potential energy. We ...

A new study suggests that researchers have achieved the most realistic robotic implementation of human walking dynamics that has ever been done, which may ultimately allow human-like versatility and ...
