If a rocket exerts a greater downward force than the force with which gravity pulls on, it will accelerate upwards.

What are the four forces on an aircraft and how do they act on an aircraft?
For an airplane to fly, it must always engage in a tug of war between the opposing forces of lift versus weight and thrust versus drag. For a moment, think of an airplane moving from right to left and the flow of air moving from left to right. The weight or force due to gravity pulls down on the plane opposing the lift created by air flowing over the wing. Thrust is generated by the propellor and opposes drag caused by air resistance to the airplane. During take off, thrust must be greater than drag and lift must be greater than weight so that the airplane can become airborne. For landing thrust must be less than drag, and lift must be less than weight. Hope this helps
How much thrust does a rocket need to take off?
i would suppose that it's because the incline is greatest then..but i suppose rocket means "something unmanned lol". the idea i have in my head says something along the lines of, the object has a path of of travel and when its moving it has a projected path of travel. so if the propellant was to be cut off when the rocket is traveling 100mph, it's not just going to stop..it has energy yet to be released. also i believe that things weigh more the faster they are going, according to Einsteins theory of relativity. but when things aren't moving they don't have a projected path of travel that is anywhere else other than where it is, then. so probably because motion must be established, and once it is, the forward motion of the object aids the propellant, if you will..or is less resistance for the propellant.
What is aerodynamic?
Aerodynamics is the study of the way in wich objects move through the air. If something such as a car has an aerodynamic shape or design, it goes faster and uses less fuel than other cars because the air passes over it more easily. The form of a aerodynamic is used as a modifier.
Why do you need to have esp to calculate the u trap size for condensate drain in ahu?
Because the weight of the water in the trap must be greater than the esp or the trap will be ineffective,and the trap size dictates how much water it can hold thus determining the weight.
What is power-to-weight ratio of steam turbine and gas turbine?
there is a mathematical formula to figure the actual power measured in Inchpounds of torque for both types of turbine engines. due to the light weight of the engine and the very high speeds in which they operate they are very efficient compared to other type of power plants generally the rough power to weight ratio of a typical aircraft turbine engine is around 85 to 95% output power compared to the actual weight of the type engine used.the exception to this would be a turbo-fan engine used on high speed aircraft which the power output is measured in footpounds of thrust
Which must be overcome by a rockets thrust?
The payload's weight, and the weight of the rocket itself.
What must airplanes and rockets do to fly through the air?
They must have sufficient thrust from their engines and lift from their wings to overcome their weight and the aerodynamic drag forces. Most rockets do not have sufficient wings to lift them but their engines provide a thrust force that is greater than their weight and it keeps pushing them vertically in the air.
During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?
thrust of the rocket engine
What happens to the four forces in order to make an airplane fly?
The four basic forces acting on an aircraft are Lift, Weight (Gravity), Thrust, and Drag. In order for an aircraft to ascend, Lift must be greater than Weight, and Thrust must be greater than Drag.
How much thrust does a rocket need to get to outer space?
Any amount of thrust greater than the total weight of the complete vehicle is enough to do the job, if the thrust lasts long enough and points in the right direction.
What will happen if the weight of an object is greater than the weight of the water that it displaces?
It will sink.
What is required for a rocket to lift out of space?
Thrust . i mean a force required to overcome the gravity of earth and which is greater than its weight.
How much force a rocket needs to take off?
That depends on its weight. Minimally it must exert a thrust greater than or equal to its own weight, or it will just sit there.
What are some advantages and dis advantages of the rocket?
rockets have more disadvantages than advantages rockets are extremely inefficient they consume enormous amounts of fuel, and most still use liquid propellant which is hard to find in space, they do however have a huge thrust to weight ratio
If the weight of an object is greater than the weight of the water that it displaces what will happen?
It will sink, because it has a greater density (the same volume weighing more)
What are the four forces that act on an airplane in flight?
Lift, weight, thrust and drag.
What is the difference between thrust and weight?
force applies perpendicularly is called thrust force which earths exerts on objests is weight
