Gravity friction and air resistance
WebFriction and air resistance are negligible. Is the tension in the cable greater than, less than, or equal to the gravitational force on the elevator? Explain. Include a free-body diagram as part of your explanation. The tension must be greater than the weight, because the difference in these forces will provide the acceleration. WebAnswer (1 of 2): it is easier to explain it by example. On earth, gravity is the force an object feels pulling it towards the center of the earth. Air resistance is the force an object feels …

Experiment with friction as a force between surfaces which slows moving objects and may prevent them from starting to move. Be sure to complete the accompanying lab sheet!
WebThe gravitational force pulls the parachute in a downward direction, whereas an air resistance force is applied to the parachute in an upward direction. Hence, the air resistance force helps the person to land smoothly on the ground. 3. Walking in Storm It is often difficult to walk in stormy weather. The value of g is 9.8 meters per square second on the surface of the earth. The gravitational acceleration decreases with the square of the distance from the center of the earth. But for most practical problems in the atmosphere, we can assume this factor is constant. If the object were falling in a … See more An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object, and the second force is the … See more The motion of any moving object can be described by Newton’s second law of motion, force F equals mass m times acceleration a: See more The drag force depends on the square of the velocity. So as the body accelerates its velocity and the drag increase. It quickly reaches a point … See more
Webspeed). Air friction and internal friction losses were assumed as nonsignificant in order to focus the study on the rolling resistance phenomena. To dispense the force of gravity component in ... WebThe second effect to be considered is the rotation of the Earth. If you are standing on the equator, you appear to weigh less because part of the force of gravity is needed to keep you rotating with the earth; while you think …
