What are the forces?

Lift,thrust ,drag ,and gravity

What does airfoil?

a structure with curved surfaces designed to give the most favorable ratio of lift to drag in flight, used as the basic form of the wings, fins, and horizontal stabilizer of most aircraft.

What is Bernoulli's principle?

It explains how the faster moving has lower air pressure than slower moving air.

How do airplanes fly?

They first collects momentum by thrusting(using a jet or propellers). In order to get off the ground the wings tilt allowing the air to move upward. When it gets to the height that it wants and needs it can decrease the angle of attack. Gravity weighs it down but lift raises it up making is straight while rushing through the air with propellers and jets.

What are the forces that always work against trying to take flight?

gravity and drag

How do helicopters fly?

Unlike airplanes, helicopters feature spinning wings called blades or rotors on top. As a helicopter's blades spin, they create a force called lift that allows the helicopter to rise into the air. ... For example, helicopters can move straight up or down and hover in the air without moving.

What does mass mean?

Mass is a combination of the total number of atoms, the density of the atoms, and the type of atoms in an object.

What is the second law of Newton explained?

Acceleration of an object or thing depends on the mass of the object or the force applied.

Explain inertia in the laws of newton.

Object will remain at rest or in a uniform motion unless acted upon by an external unbalanced force.

who is Issac Newton?

The founder of The Laws of Motion.

What is the last Newton law?

For every action there is an equal and an opposite reaction.

Why are some living things able to fly?

The forces that work in favor of them(lift and thrust) outway the ones working against them(gravity and drag).
