Question:
A 120-lb pilot flies a jet trainer in a half vertical loop of 3600-ft radius so that the speed of the trainer decreases at a constant rate. Knowing that the pilot??s apparent weights at points A and C are 380 lb and 80 lb, respectively, determine the force exerted on her by the seat of the trainer when the trainer is at pointB.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
