When a pendulum moves away from its resting position, gravity forces it to swing back. This force is a function of the earth's constant acceleration due to gravity, the pendulum bob's mass and the angle between the pendulum and the vertical.

اقرأ أكثرNote 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.

اقرأ أكثرMinimizing Impact Force. The process of minimizing an impact force can be approached from the definition of the impulse of force: . If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the time average of the impact force by the same factor. This principle is applied in many common-sense situations:

اقرأ أكثرEnergy is defined as the ability to do work. During an impact, an object's energy is converted into work. The energy of a moving object is called kinetic energy, and is equal to one half of the object's mass times the square of its velocity: KE = 0.5 × m × v^2.When thinking about the impact force of a falling object, you can calculate the energy of the object at its point of impact if you ...
