Apparent weight of moving car over a convex or concave bridge is the amount of Normal Reaction the car recives while travelling over the bridge. Here the system consists of the car, the bridge which is either convex or concave and the motion of the car along the curvature. So to start off we can

Torque formula and Torque definition in physics: These are the pointers for our discussion in this post. To start off, let’s see what is torque. Torque is the rotational equivalent of force. As force gives a push and pull for the translational motion domain, torque provides a twist in rotational motion. In other words, as

Weightless astronaut-Weightlessness in Orbiting Satellites In this post we will discuss how does an astronaut feel weightless in a nearby orbit and what is the secret behind this weightlessness in a satellite? To start with lets see how we feel this weight. If an object rests on a surface, its weight acts downwards on the

Angular Momentum – definition When an object moves with an angular speed ω along the circumference of a circular path of radius r, then we say that it has an angular momentum. Angular momentum is the rotational equivalent of linear momentum and is defined as the moment of Linear momentum. It depends on 2 quantities,
