Down ward force is greater than upward force because everything on earth, obeys the laws of gravity, and for a rocket to take off from earth it needs more energy in other to fight the earths gravitational force but despite fighting the gravitational force it still doesnt take off with a full speed, But for a body of mass to fall from the atmosphere its falls with a great speed due to the force of the earths gravity.

∙ 9y agoIt depends entirely on the situation.
If the object is resting, the upward and downward forces must be equal. On a planet, like Earth, this would make the normal force (upward) and gravitational force (downward) the same quantity. In outer space, it would simply be inertia. If the object is falling, the upward force is less than the downward force. If the object is rising, the upward force is greater than the downward force.

What is effect of the weight of the helicopter on the terminal speed?
When an object falls in the air, the air resistance opposing its motion increases as its speed rises, so reducing its acceleration. Eventually air resistance acting upwards equals the weight of the object acting downwards. The resultant force on the object is then zero since the two opposing forces balance. The object falls at a constant velocity, called its terminal velocity, whose value depends on the size, shape and weight of the object. This is just like Newton's laws, an object will accelerate if the forces acting upon it are unbalanced; and further, the amount of acceleration is directly proportional to the amount of net force (unbalanced force) acting upon it. Falling objects initially accelerate (gain speed) because there is no force big enough to balance the downward force of gravity. Yet as an object gains speed, it encounters an increasing amount of upward air resistance force. In fact, objects will continue to accelerate (gain speed). Or summat like that...

What are the terms for rolling motions of the foot?
Rolling motions of the foot are described as inversion (rolling with the big toe initially lifting upward) and eversion (rolling with the big toe initially moving downward).
What forces must an engineer consider when designing a barge?
The forces are BIG Farts. The air is just so strong. People love the smell of it. They love to sniff the air like a wolf so much. And the activies that are carried are... SHITING! -Shandi.
