Force and Acceleration
... For example, when we are traveling in a bus, and bus is going at fast speed. The driver suddenly applies the brake and we are unable to control ourselves and our body plunges forward. It is because the bus and our body are moving at constant velocity. That is why in cars etc. we use seat belts. So t ...

... • Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or which can cause a flexible object to deform. A force has both magnitude and direction, ...

... • Tidal forces arise from the differences between the gravitational forces at Earth’s near surface, center, and far surface. • As the distance (r) between two bodies increases, the tidal force decreases as 1/r3. For this reason, the sun, which has a greater mass than the moon does, has less effect o ...
