Step 2: Now click the button "Calculate the Unknown" to get the time period.

### Simple pendulum via Lagrangian mechanics

where q signifies generalized coordinates and F signifies non-conservative forces acting on the mechanical system. For the simplify pendulum, we assume no friction, so no non-conservative forces, so all F i are 0. The aforementioned equation of motion is in terms of as a coordinate, not in terms of x and y. So we need to use kinematics to get ...

### Impact Force from Falling Object - HyperPhysics Concepts

Note that the above calculation of impact force is accurate only if the height h includes the stopping distance, since the process of penetration is further decreasing its gravitational potential energy.. The average impact force calculated here is the average over distance, which can be presumed to be proportional to, but not the same as, the average over time.

### Impact Force - Engineering ToolBox

The impact on a human body can be difficult to determine since it depends on how the body hits the ground - which part of the body, the angle of the body and/or if hands are used to protect the body and so on. For this example we use an impact distance of 3/4 inch (0.0625 ft) to calculate the impact force: F avg = (800 ft lb) / …

### Piezoelectric sensor - Wikipedia

A piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated) A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo- is Greek for 'press' or 'squeeze'.
