Elevator slowing down weight
WebThe tension must be greater than the weight, because the difference in these forces will provide the acceleration. It is clear, that since the elevator is going down and slowing down, the acceleration points upwards. Therefore, the greater force is the tension force. WebFeb 25, 2012 · In choice A, the elevator is moving downward, and slowing down. That means the hanging weight is being exposed to a changing velocity, or acceleration, in …

WebTwo forces act on the block, its weight and the normal force exerted by the surface of the table. Newton's third law plays an important role in connection with the normal force. In Figure 4.13, for instance, the block exerts a force on the table by pressing down on it. Consistent with the third law, the table exerts an oppositely directed force ... WebSo for a short time, we are pushed into the floor more and our weight goes up. The same thing works when the elevator starts moving. Our body is happy to be standing still. But …
