... Out of common experience, we know that any change in velocity must be due to an interaction between an object (a body) and something in its surroundings. An interaction that can cause an acceleration of a body is called a force. Force can be loosely defined as a push or pull on the body. The r ...

... A block is pushed across a rough horizontal surface from point A to point B by a force (magnitude P = 5.4 N) as shown in the figure. The magnitude of the force of friction acting on the block between A and B is 1.2 N and points A and B are 0.5 m apart. If the kinetic energies of the block at A and B ...

... the law of inertia is shown in Figure 3.2-1. The vehicle and the cooler on the roof were traveling at a certain velocity, until the vehicle experienced the unbalanced force from the wall. The force from the wall is great enough to drastically change the velocity of the vehicle, causing it to stop. A ...
